Guide for Authors
Our journal publishes different types of documents: research and review articles; short communications; technical notes; Biotechnology Issues for Developing Countries; book reviews;commentaries; and correspondence.
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 greather 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.
First page of the article:
It should contain the following information:
Authors must include the financial support received for research.
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.
Authors should provide their present address in case it is different than the affiliation described at the Title page.
The abstract of the manuscript should not exceed 350 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 Please minimize the use of abbreviations and do not cite references in the abstract.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.
The acknowledgments of the contributions of colleagues can be stated in this section. Acknowledgments for financial support must be cited on the corresponding section.
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. Citations from thesis, personal communications, and unpublished data are not allowed.
a) In the text:
References must be cited in the text mentioning the last name of the author and year between parenthesis. In case of two authors, both should be mentioned. When there are three or more authors, mention only the first author followed by et al. When two or more references are cited in the same parenthesis, the authors should be in chronological order. And if they have the same year, they should be in alphabetical order. Moreover, if there is more than one reference of the same author and the same year, they should be indicated with letters.
b) In the References section:
At the end of the paper, in the References section the literature should be arranged in alphabetical order. If they have the same author, they should be in chronological order. They must be presented according to the following examples:

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) in order to make formal changes (colour, fonts, size, etc.).
Digitalized photographs must be sent using a TIFF format, with a minimum of 300 dpi. Also GIF and JPG formats can be used.
Special care on the maximum definition of the photographs is required.
Drawings and graphs
For line art, the following software can be used: Excel, Power Point, Adobe Illustrator 8 EPS, Freehand 8, Canvas 6, and Postcript Level 2.
We accept digitized videos using mpg format.
Nucleotide and Aminoacid Sequences
New sequence data referred to in a manuscript should also be reported with their accession number assigned in the DDBJ/EMBL/GenBank sequence data libraries. A manuscript can be submitted while sequence data is being entered into the data libraries with the intent of including accession numbers once the manuscript is approved for publication.
Accession numbers are best presented in a separate paragraph at the end of the Materials and Methods section.
