AÇÃO INIBITÓRIA DE MICOCINAS PRODUZIDAS POR WICKERHAMOMYCES ANOMALUS EM SALMONELLA MINNESOTA ISOLADAS DE CARNES DE FRANGO

Abstract

The export and consumption of chicken meat in Brazil have been progressively increasing, demanding rigorous microbiological analyses to ensure food safety. Among the most relevant pathogens is Salmonella minnesota, a serovar associated with antimicrobial resistance and frequently detected in poultry products. This study aimed to evaluate the production of β-1,3-glucanases by the yeast Wickerhamomyces anomalus and its antimicrobial activity against S. minnesota strains isolated from chicken meat. A total of 73 Salmonella spp. isolates were typified, of which 27 were confirmed as S. minnesota. The antimicrobial action of the mycocins was assessed through solid media and microdilution assays, with complete inhibition of all 27 strains observed at a concentration of 0.11 U/mg of β-glucanases present in the supernatant of the W. anomalus WA40 strain. The results indicate that the mycocins have potential as biocontrol and biopreservation agents in the poultry industry.
