- Bacterial ecology of tilapia fresh fillets and some factors that can influence their microbial quality Cleube Andrade BOARI Gisele Inocêncio PEREIRA Carolina VALERIANO Belami Cássia SILVA Vinicíus Mendes de MORAIS Henrique Cesár Pereira FIGUEIREDO Roberta Hilsdor PICCOLI Agrociencias tilapia quality fillets aquaculture Microbiology The purpose of research was to investigate the bacterial ecology of tilapia (Oreochromis niloticus) fresh fillets and some factors that can influenceits microbial quality. Samples of fish cultivation water (n = 20), tilapia tegument and gut (n = 20) and fresh fillets (n = 20) were collected in anexperimental tilapia aquaculture located in the city of Lavras, Minas Gerais, Brazil.Staphylococcusspp.,Aeromonasspp.,Enterococcusspp. andEnterobacteriaceae were quantified using selective plating. For the enumeration ofPseudomonasspp., the most probable number technique(MPN) was utilized. Bacterial colonies (n = 198) were identified by Gram strain and biochemical tests.Aeromonasspp.,Pseudomonasspp.,Enterococcusspp. and Enterobacteriaceae were found in the cultivation water (water from a fishpond cultivation), tegument, gut, and freshfillets.Staphylococcusspp. was not isolated in the cultivation water.Salmonellaspp. was not detected. The count variable of 10 to 103CFU orMPN.(g or mL)–1. Associated to freshwater tilapia fillet processing, there is a large variety of microorganisms related to foodborne illnessesand fish products deterioration. 2008 artículo científico 0101-2061 https://www.redalyc.org/articulo.oa?id=395940089015 en http://www.redalyc.org/revista.oa?id=3959 Ciência e Tecnologia de Alimentos application/pdf Sociedade Brasileira de Ciência e Tecnologia de Alimentos Ciência e Tecnologia de Alimentos (Brasil) Num.4 Vol.28
