Název v původním jazyce

Detection of psychrotrophic bacilli in raw and pasteurized milk using microbiological and PCR methods

Popis výsledku v původním jazyce

Aerobic spore-forming bacteria of the genus Bacillus are commonly present in raw milk. Their spores can survive pasteurization and UHT temperature and can be causative agent of some alimentary diseases. Therefore the microbiological control of milk quality includes monitoring of this genus. In this work, the detection of bacteria of the genus Bacillus in raw and pasteurized milk samples was carried out. All milk samples collected showed good hygienic quality. All presumptive strains isolated on selective MYP agar were classified to be of genus Bacillus using PCR (Wu et al., 2006). The results show, that this PCR metod is suitable for rapid screening of the presence of Bacillus spp. in raw and pasteurized milk. Except mesophilic Bacillus isolates, fourpsychrophilic bacilli strains were isolated from raw milk samples and two from pasteurized milk. These psychrophilic strains schould assist in microbial proteolysis and lipolysis of pasteurized milk during storage and deteriorate the milk
