Microbial penicillinase in soft types of cheese.

Penicillinase activity was found in commercial samples of Limburger, Liederkranz, and Brick, as well as in Roquefort and Danish Blue cheeses. The numbers of penicillinase-producing bacteria in the cheese flora were estimated by use of the most probable numbers technique coupled with penicillinase determinations on the individual cultures. Although streptococci constituted the predominant flora ...

Microbial interactions in cheese: implications for cheese quality and safety.

The cheese microbiota, whose community structure evolves through a succession of different microbial groups, plays a central role in cheese-making. The subtleties of cheese character, as well as cheese shelf-life and safety, are largely determined by the composition and evolution of this microbiota. Adjunct and surface-ripening cultures marketed today for smear cheeses are inadequate for adequa...

Microbial interactions within a cheese microbial community.

The interactions that occur during the ripening of smear cheeses are not well understood. Yeast-yeast interactions and yeast-bacterium interactions were investigated within a microbial community composed of three yeasts and six bacteria found in cheese. The growth dynamics of this community was precisely described during the ripening of a model cheese, and the Lotka-Volterra model was used to e...

Evaluation of chemical and microbial properties of Iranian white cheese using kefir, yogurt and commercial cheese culture as a starter

In this research, the chemical and microbiological characteristics of white brined cheeses produced with five different starter cultures, namely: traditional kefir grain, commercial kefir, commercial yogurt, traditional yogurt and commercial cheese starter culture, were examined during 60-day ripening period. Results of statistical analysis showed that the type of starter culture had a signific...

Occurrence of various types of penicillinase plasmid among 'hospital' staphylococci.

The type of penicillinase plasmid carried by penicillin-resistant cultures of Staphylococcus aureus isolated from eight London hospitals has been determined. Among ;endemic' hospital staphylococci, cultures resistant to mercury salts and producing large amounts of A-type penicillinase, a high proportion of which is extracellular, are most common. C-type penicillinase is rarely associated with r...
