The Pantothenic Acid Requirements of Lactic Acid Bacteria

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...

Some Mineral Requirements of the Lactic Acid Bacteria*

Although the requirements of several lactic acid bacteria for organic nutrients are known in considerable detail (1,2), knowledge of the mineral nutrition of this same group of bacteria is scanty. In chemically defined media, the mineral mixture most commonly used has been that of Speakman (3), which contains K+, Naf, Mg++, Mn++, Fe++, PO,“, S04* and Clions. Of these, previous investigations ha...

Lactic Acid Bacteria

Lactic acid bacteria comprise an ecologically diverse group of microorganisms united by formation of lactic acid as the primary metabolite of sugar metabolism (Davis et al., 1985b; 1988; Lonvaud-Funel, 1999; Carr et al., 2002; Liu, 2002). These bacteria utilize sugars by either homoor heterofermentative pathways (Section 2.4.1) as well as l-malic acid, a major acid present in grape must (Sectio...
