- Enzymatic and antagonistic potential of bacteria isolated from typical fruit of Cerrado in Minas Gerais State, Brazil Cristina Ferreira Silva Kelly Cristina dos Reis Noelly Alves Lopes Mariana Dias Luis Roberto Batista Rosane Freitas Schwan Agrociencias Microorganism Psychotria hoffmannseggiana biotechnological application Brazil has great biodiversity, which is obse rved in the Cerrado biome of the tropical Brazilian savanna. The objectives of this stud y were to isolate and identify bacteria from Psychotria hoffmannseggiana with potential cellulase and pectinase produc tion and with antagonistic activity against Aspergillus carbonarius , an Ochratoxin A (OTA) producer. Ripe frui t were collected in the region of Passos City in the preserved Cerrado area in Minas Gerais St ate, Brazil. Serial dilution s were performed, and the bacteria isolated were biochemically characterized and identified by sequencing. To analyze the production of enzymes, the bacteria were cultivated in CMC an d pectinase media. The better enzyme producers were optimized for production. Assays on the antagonistic activity for growth and sporulation were carried out in co-culture (bacteria and filamentous fungi). TLC was performed to verify the mycotoxin production. The predominant microbiota were Gram-negative bacteria belonging to the Enterobacteriaceae family. Some isolates showed potential for enzymatic and antagonist ic activity, especially the isolate identified as Lysinibacillus fusiformis . This species was a better producer of cellulases (maximu m activity: 103.1 mg glucose min. -1 mg -1 protein). In conclusion, the bacteria isolated from Psychotria hoffmannseggiana showed biotechnological potential for agro-industry and the environmental aspect. 2015 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303041016013 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
