CRUZ-LEYVA, María Concepción de la et al. Studies and importance of microbial communities in fishery resources and products. Ecosistemas y recur. agropecuarios [online]. 2015, vol.2, n.4, pp.99-115. ISSN 2007-901X.

Microorganisms are an essential part of life in the planet. The bacterial flora is an crucial component of trophic webs in marine ecosystems, both in activity and quantity of biomass, contributing to nutrient recycling and establishing complex interactions with a wide range of organisms. To understand its role in specific niches, it is essential to identify and quantify each of the members who make up these communities, then to infer the taxonomic and genetic diversity in the analyzed sample. For food products, these analyses may bring information on possible effects on the health of the consumer or may allow the isolation of microbial strains or metabolites useful in biotechnological processes. Health of the consumer. Furthermore, this knowledge can provide, the use of strains or microbial metabolites in biotechnological processes. An efficient alternative for the investigation of bacterial communities in complex samples has been the analysis of the 16S rRNA gene by fingerprinting methods as RAPD, TRFLP and DGGE. In this context, several authors indícate that fish stocks have an abundant associated bacterial flora bearing biotechnological potential or that may help, prevents damages to the fishery resource and final consumers.
