Strain lactobacillus

A Lactobacillus strain was recently shown to inhibit competitively adhesion of enteropathogenic E. coli to pig ileum and interfered with bacterial attachment to the mucosal layer of ileal conducts (Blomberg et al., 1993). Although L. acidophilus inhibits the adhesion of several enteric pathogens to human intestinal cells in culture, when pathogen attachment preceded L. acidophilus treatment, no inhibitory interference occurred indicating that steric hindrance of site occupation is important in the inhibition of adhesion. Thus, therapeutic use is likely to be limited to preventive application of probiotics.

Enzyme-catalyzed syntheses of enantiomeric pure hydroxy acids use lactate dehydrogenases (LDH E.C. 1.1.1.27) or hydroxyisocaproate dehydrogenases (HicDH). Both kinds of enzymes are available as D- or L-specific catalysts. L-specific [5, 6] LDHs as well as D-specific [7-10] LDHs favorably catalyze the reduction of pyruvate, HicDHs (and mandelate dehydrogenase, too) convert keto acids with longer aliphatic or aromatic side chains. These enzymes can be isolated from Lactobacillus strains [11-14].

When screening a large number of Lactobacillus strains for lactate production using hemicellulose hydrolysate, strains L. pentosus CHCC2355 and L. brevis CHCC2097 were selected and evaluated further (Garde et al, 2002). Each strain produced lactate with 88% (for L. pentosus) and 61% of the theoretical yield (L. brevis), respectively, from wheat straw hydrolysate without visible inhibition. The operation of the phosphoketolase pathway in these... 

Nair and Pradeep (2002) have reported that common Lactobacillus strains found in buttermilk, when challenged with silver and gold ions, assisted the growth of microscopic gold, silver, and gold silver alloy crystals of well-defined morphology within the bacterial cells. However, the exact reaction mechanism leading to the formation of silver nanoparticles by this species of silver-resistant bacteria was not...

In bacteria, insensitivity to kirromycin and pulvomycin is restricted to certain Lactobacillus strains [169], Unlike bacteria, the archaea are systematically insensitive to kirromycin [128,165] but exhibit a distribution in their response to pulvomycin [165] (Table 9). To summarize, two features, insensitivity of EF-la to kirromycin and sensitivity of EF-2 to ADP ribosylation by diphtheria toxin, are systematic of archaea. Two others (the sensitivity of EF-la to pulvomycin and the sensitivity of EF-2 to fusidic acid) are unevenly distributed amongst the archaea in a manner that reflects only vaguely the phylogenetic placements of the organisms inferred from similarities in 16S rRNA sequences. 

Jin et al. (1996) demonstrated that a combination of Lactobacillus strains isolated from chicken intestine were able to inhibit growth of five strains of Salmonella, including S. enteritidis 94/448, S. typhimurium, S. pullorum, S. blockley, and S. enteritidis 935/79, and three serotypes of E. coli, viz. E. coli 01 K1, 02 K1, and 078 K88.

L-lactic acid has long been used as a food additive and has recently received great attention because it can be used as an important feedstock for the production of other chemicals such as polylactic acid (PLA), acetaldehyde, polypropylene glycol, acrylic acid, and penta-dione. Among them, PLA is the most important product as it can be used to manufacture thermo-formed containers, packaging, nonwovens, paper-coated articles, and film products. Lactic acid can be produced from sucrose, whey (lactose), and maltose or dextrose from hydrolyzed starch using Lactobacillus strains.
