NOTICE: Electronic Journal of Biotechnology is being published through EES (Elsevier Editorial System) since the beginning of January 2014.
The Journal will continue being an Open Access publication and its articles will be additionally available -free for the readers-, through the ScienceDirect web site (www.sciencedirect.com).
Guide for Authors
Contributions falling into the following categories will be considered for publication: Original research papers, reviews and short communications.
For more information please see Content Types
All manuscripts should be prepared in English with Microsoft Word or WordPerfect and sent through Online Submissions. Figures , graphs and tables should be included in the manuscript file. Figures greater than 5.0 MB, must be send as complementary files.
Receipt of each article is acknowledged by e-mail to the contacting author upon receipt. Preliminary articles will not be considered for publication. The manuscript is read and examined for conformity to the Guide for Authors by the editor. Failure to meet the criteria outlined may result in return of the manuscript for corrections before evaluation.
The guidelines for manuscript evaluation are available here.
A galley proof is provided to the contacting author for the HTML. Upon acceptance of this version the PDF will be done and no further changes will be accepted.
1. Use of wordprocessing software
It is important that the file be saved in the native format of the wordprocessor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do use bold face, italics, subscripts, superscripts etc. The electronic text should be prepared in a way very similar to that of conventional manuscripts. Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text. See also the section on Electronic illustrations.
To avoid unnecessary errors you are strongly advised to use the "spell-check" and "grammar-check" functions of your wordprocessor.
If the LaTeX file is suitable, proofs will be produced without rekeying the text. The article should preferably be written using Elsevier's document class "elsarticle", or alternatively any of the other recognized classes and formats supported in Elsevier's electronic submissions system, for further information see http://www.elsevier.com/wps/find/authorsview.authors/latex-ees-supported.
The Elsevier "elsarticle" LaTeX style file package (including detailed instructions for LaTeX preparation) can be obtained from the Quickguide: http://www.elsevier.com/latex. It consists of the file: elsarticle.cls, complete user documentation for the class file, bibliographic style files in various styles, and template files for a quick start.
3.1. Subdivision - numbered sections
Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to "the text". Any subsection may be given a brief heading. Each heading should appear on its own separate line.
For details on structure revise section Content Types.
3.2. Essential title page information
- Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
- Short title. Provide a short title having no more than 80 characters including spaces. This will be used for metadata.
- Author names and affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name, and, if available, the e-mail address of each author.
- Contacting author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. If possible indicate an alternative e-mail for contact. Indicate if the contacting author is different from the corresponding author.
Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. Contact details must be kept up to date by the corresponding/contacting author.
- Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a "Present address" (or "Permanent address") may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
Changes to authorship
Modifications to authorship are not allowed, this policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts.
3.3. Abstract
The abstract of the manuscript should not exceed 250 words and must be structured into separate sections: Background, the context and purpose of the study; Results, the main findings; Conclusions, brief summary and potential implications. Please minimize the use of abbreviations and do not cite references in the abstract.
In case of review articles, the abstract should be submitted as one section.
3.4. Keywords
Authors must provide between three and six keywords, which must not be part of the title of the paper. Phrases and general or broad words such as "pH" or "growth" are not allowed.
3.5. Abbreviations
Define abbreviations that are not standard in this field in a footnote to be placed on the first page of the article. Such abbreviations that are unavoidable in the abstract must be defined at their first mention there, as well as in the footnote. Ensure consistency of abbreviations throughout the article.
3.6. Authors’ contributions
All persons designated as authors should qualify for authorship, and all those who qualify should be listed. Each author must have participated sufficiently in the work to take public responsibility for appropriate portions of the content. Those who contributed to the work but do not qualify for authorship, as for example only providing samples, reagents or analysis tools should be listed in the acknowledgments.
In the manuscript (before the acknowledgments) the following list of responsibilities should be completed with the name of the authors: (it´s not necessary to complete all roles)
- Proposed the theoretical frame:
- Conceived and designed the experiments:
- Software development:
- Contributed reagents/materials/analysis tools:
- Wrote the paper:
- Performed the experiments:
- Analyzed the data:
3.7. Acknowledgements and financial support
Collate acknowledgements and financial support in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language or writing assistance, or proof reading the article, etc.).
The following fields should be completed:
- Agency/Institution Financial support:
- Program Financial support:
- Project number:
- Acknowledgments:
3.8. Nomenclature and units
Follow internationally accepted rules and conventions: use the international system of units (SI) (http://physics.nist.gov/Pubs/SP330/sp330.pdf). If other quantities are mentioned, give their equivalent in SI. Authors wishing to present a table of nomenclature should do so on the second page of their manuscript.
3.9. Math formulae
Present simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text) (for example: Equation 1).
3.10. Footnotes
Footnotes should be used sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many wordprocessors build footnotes into the text, and this feature may be used. Should this not be the case, indicate the position of footnotes in the text and present the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.
3.11. References
For original articles (research, short communications, technical notes, biotechnology issues for developing countries), at least 75% of the references must be from the Science Citation Index Expanded and at the same time from the last decade. Also the DOI number must be included at the end of each reference.
3.11.1. Citation in text
Please ensure that every reference cited in the text is also present in the reference list (and vice versa). References en abstract should be avoid. Unpublished results; personal communications and thesis are not allowed.. Citation of a reference as "in press" implies that the item has been accepted for publication.
3.11.2. Web references
As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.
3.11.3. References in a special issue
Please ensure that the words 'this issue' are added to any references in the list (and any citations in the text) to other articles in the same Special Issue.
3.11.4. Reference management software
This journal has standard templates available in key reference management packages EndNote (http://www.endnote.com/support/enstyles.asp) and Reference Manager (http://refman.com/support/rmstyles.asp). Using plug-ins to wordprocessing packages, authors only need to select the appropriate journal template when preparing their article and the list of references and citations to these will be formatted according to the journal style which is described below.
3.11.5. Reference style
Text: Indicate references by number(s) in square brackets in line with the text. The actual authors can be referred to, but the reference number(s) must always be given.
Example: '..... as demonstrated [3,6]. Barnaby and Jones [8] obtained a different result ....'
Reference section: Number the references (numbers in square brackets) in the list in the order in which they appear in the text.
Examples:
Reference to a journal publication:
[1] Van der Geer J, Hanraads JAJ, Lupton RA. The art of writing a scientific article. J Sci Commun 2000;163:51-9. Doi: http://dx.doi.org/doi.

4.1. Electronic artwork
General points
- Make sure you use uniform lettering and sizing of your original artwork.
- Save text in illustrations as "graphics" or enclose the font.
- Only use the following fonts in your illustrations: Arial, Symbol.
- Number the illustrations according to their sequence in the text.
- Use a logical naming convention for your artwork files.
- Provide captions to illustrations separately.
- Produce images near to the desired size of the printed version.
- Submit each figure as a separate file.
A detailed guide on electronic artwork is available at: http://www.elsevier.com/artworkinstructions.
4.2. Formats
Regardless of the application used, when your electronic artwork is finalized, please "save as" or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):
EPS: Vector drawings. Embed the font or save the text as "graphics".
TIFF: color or gray scale photographs (halftones): always use a minimum of 300 dpi.
TIFF: Bitmapped line drawings: use a minimum of 1000 dpi.
TIFF: Combinations bitmapped line/half-tone (color or gray scale): a minimum of 500 dpi is required.
If your electronic artwork is created in a Microsoft Office application (Word, PowerPoint, Excel) then please supply "as is".
Please do not:
- Supply files that are optimized for screen use (like GIF, BMP, PICT, WPG); the resolution is too low;
- Supply files that are too low in resolution;
- Submit graphics that are disproportionately large for the content.
4.3. Color artwork
Please make sure that artwork files are in an acceptable format (TIFF, EPS or MS Office files) and with the correct resolution. If, together with your accepted article, you submit usable color , then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., Science Direct and other sites) regardless of whether or not these illustrations are reproduced in color in the printed version.
Ensure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.
The figures (photographs, drawings) must be numbered with Arabic numerals. Footnotes can be included below the figure.
Figures that include more than one image should be labeled as a, b, c, etc. (lower case, use black or white bold according to the figure).
Example:
They should be cited as figures and must be numbered with Arabic numerals. Footnotes can be included below the figure.
Graphs that include more than one image should be labeled as a, b, c, etc. (Arial lower case). They must be in 2D and have a title. In case they have legend, it must be placed below the image. They should be built with Arial font and in the colour palette called "Trek" (warm earth colours). See page layout in MS Office 2007. For the Spanish version the colour palette is called "Viajes". Graphs must be send in editable formats (MS excel if possible. We also accept Sigma plot and Origin) in order to make formal changes (colour, fonts, size, etc.).
Examples:
Colum chart:
Line Chart:
Tables must be numbered with Arabic numerals in the order in which they are cited in the text. They should have a brief descriptive title placed at the top. A short description is also accepted. Avoid vertical rules. Place footnotes to tables below the table body and indicate them with superscript lowercase letters. Tables must be sent in Microsoft Word and have no links to the main document or other archives. Provide files at approximately the correct size they are to be printed (letter size).
When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns.
Example:
Elsevier accepts video material and animation sequences to support and enhance your scientific research. Authors who have video or animation files that they wish to submit with their article are strongly encouraged to include links to these within the body of the article. This can be done in the same way as a figure or table by referring to the video or animation content and noting in the body text where it should be placed. All submitted files should be properly labeled so that they directly relate to the video file's content. In order to ensure that your video or animation material is directly usable, please provide the files in one of our recommended file formats with a preferred maximum size of 50 MB. Video and animation files supplied will be published online in the electronic version of your article in Elsevier Web products, including ScienceDirect: http://www.sciencedirect.com.
AUTHOR INFORMATION PACK 9 Oct 2013 www.elsevier.com/locate/jbiotec 12
Please supply 'stills' with your files: you can choose any frame from the video or animation or make a separate image. These will be used instead of standard icons and will personalize the link to your video data. For more detailed instructions please visit our video instruction pages at http://www.elsevier.com/artworkinstructions. Note: since video and animation cannot be embedded in the print version of the journal, please provide text for both the electronic and the print version for the portions of the article that refer to this content.
4.8. Nucleotide and Aminoacid Sequences
DNA sequences and GenBank Accesion numbers: Many Elsevier journals cite "gene accession numbers" in their running text and footnotes. Gene accession numbers refer to genes or DNA sequences about which further information can be found in the database at the National Center for Biotechnical Information (NCBI) at the National Library of Medicine. Elsevier authors wishing to enable other scientists to use the accession numbers cited in their papers via links to these sources, should type this information in the following manner:
For each and every accession number cited in an article, authors should type the accession number in bold, underlined text. Letters in the accession number should always be capitalised. (See Example 1 below). This combination of letters and format will enable Elsevier's typesetters to recognize the relevant texts as accession numbers and add the required link to GenBank's sequences.
Example 1: "GenBank accession nos. AI631510, AI631511, AI632198, and BF223228, a B-cell tumor from a chronic lymphatic leukemia (GenBank accession no. BE675048), and a T-cell lymphoma (GenBank accession no. AA361117".
Authors are encouraged to check accession numbers used very carefully. An error in a letter or number can result in a dead link. In the final version of the printed article, the accession number text will not appear bold or underlined (see Example 2 below).
Example 2: "GenBank accession nos. AI631510, AI631511, AI632198, and BF223228, a B-cell tumor from a chronic lymphatic leukemia (GenBank accession no. BE675048), and a T-cell lymphoma (GenBank accession no. AA361117)".
In the final version of the electronic copy, the accession number text will be linked to the appropriate source in the NCBI databases enabling readers to go directly to that source from the article.
