Enhancement in cell mass concentration of lactic acid bacteria with fed-batch preculture technique.

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...

Cell wall composition of lactic acid bacteria.

After the discovery of methods for the isolation of bacterial cell walls (l), it was established that walls of gram-positive organisms contain relatively few amino acids. The most frequently occurring and abundant of these are alanine, glutamic acid, aspartic acid, lysine, and diaminopimelic acid. Walls of grampositive organisms also contain large amounts of sugars and amino sugars and are rela...

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...
