Antagonistic interaction between yeasts and lactic acid bacteria of oenological relevance

Analysis of cellular adhesion between lactic acid bacteria and yeasts

Antagonism between osmophilic lactic Acid bacteria and yeasts in brine fermentation of soy sauce.

Brine fermentation by osmophilic lactic acid bacteria and yeasts for long periods of time is essential to produce a good quality of shoyu (Japanese fermented soy sauce). It is well known that lactic acid fermentation by osmophilic lactic acid bacteria results in the depression of alcoholic fermentation by osmophilic yeasts, but the nature of the interaction between osmophilic lactic acid bacter...

Genetic screening of lactic acid bacteria of oenological origin for bacteriocin-encoding genes.

A total of 330 lactic acid bacteria isolated from South African red wines during alcoholic and malolactic fermentations and 9 commercial malolactic bacteria starter cultures were screened for antimicrobial activity. Of the entire screened isolates, 26 strains, belonging to the species Lactobacillus plantarum, Lactobacillus paracasei, Lactobacillus hilgardii and Oenococcus oeni, showed activity ...

Antimicrobial Effect of Lactic Acid Bacteria against Common Pathogenic Bacteria

Abstract       Background and Objective: Probiotics are living microorganisms that have beneficial effects on the health of digestive system. The aim of this study was to evaluate the antimicrobial ability of acidic and neutral supernatants (culture supernatant) of lactic acid bacteria against common bacterial pathogens.        Meth...

The interaction between yeasts and bacteria in dairy environments.

The general environment from which raw dairy products originate and the microbiological quality of the products in its processed state inevitably admit yeast growth and spoilage. Only part of the primary microflora survives under the selective pressures exerted by the intrinsic and extrinsic biotic factors present, processing procedures and preservatives. Yeasts that possess the proper physiolo...
