Abstract

GUTIERREZ-JIMENEZ, Javier et al. Organization, maintenance, and preservation of the Bacterial Culture Collection of the Biological Sciences Institute, University of Science and Arts of Chiapas (UNICACH), Mexico. Rev. Soc. Ven. Microbiol. [online]. 2015, vol.35, n.2, pp.95-102. ISSN 1315-2556.

Strain collections or bacterial culture collections are genetic resources whose purpose is the preservation of biological diversity, ensuring their availability for teaching, research and trade activities. In this work viability, purity and biological characteristics of bacteria from the bacterial collection of the Institute of Biological Sciences, University of Science and Arts of Chiapas were studied. Information was structured and organized in a virtual site, to promote academic cooperation. The strain bank includes 33 microorganisms, most of the genus Streptococcus and Escherichia (45.1 and 21.2%, respectively). For Streptococcus, the identification of S. pyogenes (40%) was confirmed, by determination of most DNAses encoding genes. For Escherichia 58.3% were taxonomically confirmed as E. coli. For this species, the collection includes typical strains that produce diarrhea and their genetic traits have been preserved for more than five years. This bacterial culture collection has stimulated teaching and research activities at local and international levels. Strain collections are important sources of biological material which can provide bacterial species, in order to encourage interaction with the academic community.

Keywords : organization; preservation; bacterial culture collection.
