- Isolation and characterization of bacterial strains with a hydrolytic profile with potential use in bioconversion of agroindustial by-products and waste Cintia Anabela MAZZUCOTELLI Alejandra Graciela PONCE Catalina Elena KOTLAR María del Rosario MOREIRA Agrociencias bioconversion waste management Hydrolytic profile There is a trend towards the use of novel technologies nowadays, mainly focused on biological processes, for recycling andthe efficient utilization of organic residues that can be metabolized by different microorganisms as a source of energy. In thepresent study the isolation of bacterial strains from six different agro-industrial by-products and waste was performed with theobjective of evaluating their hydrolytic capacities and suitability for use in bioconversion of specific substrates. The 34 isolatedstrains were screened in specific culture media for the production of various hydrolytic enzymes (lipase, protease, cellulase, andamylase). It was found that 28 strains exhibited proteolytic activity, 18 had lipolytic activity, 13 had caseinolytic activity, 15 hadamylolytic activity, and 11 strains exhibited cellulolytic activity. The strains that showed the highest hydrolytic capacities withbiotechnological potential were selected, characterized genotipically, and identified asBacillus,Serratia,Enterococcus,Klebsiella,Stenotrophomonas,Lactococcus,andEscherichiagenera. It was concluded that the strain isolates have a high potential for usein the bioconversion of agro-industrial waste, both as a pure culture and as a microbial consortium. 2013 artículo científico 0101-2061 https://www.redalyc.org/articulo.oa?id=395940116013 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.2 Vol.33
