Abstract
Lipolytic and proteolytic psychotrophs were isolated from raw and pasteurized goats'' milk, which had been stored at 5.degree. C for 7 d. The 241 strains isolated and 20 reference stains were examined by 149 biochemical, physiological, and morphological tests. The results yielded 195 characters suitable for taxonomic analysis. Computer-assisted complete linkage analysis, using the Jaccard coefficient, producted 22 phenons at 75% S. The results showed that Pseudomonas fluorescens was the predominant psychrotrophic bacterium, but that Pseudomonas fragi was dominant in some milk samples. Strains of Serratia liquefaciens and Flavobacterium balustinum were also identified.This publication has 45 references indexed in Scilit:
