摘要：

This study explored the microbiota of Formaella, Kopanisti, Feta and Mana cheeses. A total of 133 wild lactic acid bacteria were isolated and classified phenotypically. Mesophilic lactobacilli were the most abundant group. Thermophilic lactobacilli and thermophilic cocci were the best milk acidifiers, whereas thermophilic lactobacilli were the most proteolytic isolates. Higher peptidolytic and esterolytic activities were obtained with thermophilic cocci. Only five isolates were lipolytic, whereas none was able to catabolize citrate. Fast gas chromatography-mass spectrometry analysis of the metabolites produced and subsequent principal components analysis revealed segregated groups of isolates in accordance with the phenotypic ones. Electronic nose analysis revealed similar results. Lactobacillus rennini and Lactobacillus acidipiscis were found to be the sole microbial species in Kopanisti cheese and Mana. These isolates produced alcohols and aldehydes as major volatile compounds, as a result of secondary amino acid catabolism. (C) 2009 Elsevier Ltd. All rights reserved.
