BACKGROUND Previous studies have revealed that the C-terminal region of the S-layer protein from Lactobacillus is responsible for the cell wall anchoring, which provide an approach for targeting heterologous proteins to the cell wall of lactic acid bacteria (LAB). In this study, we developed a new surface display system in lactic acid bacteria with the C-terminal region of S-layer protein SlpB ...

Normal-gravity (22 to 24 degrees Plato) wheat mashes were inoculated with five industrially important strains of lactobacilli at approximately 10(5), approximately 10(6), approximately 10(7), approximately 10(8), and approximately 10(9) CFU/ml in order to study the effects of the lactobacilli on yeast growth and ethanol productivity. Lactobacillus plantarum, Lactobacillus paracasei, Lactobacill...

Objective: An investigation of isolation of Lactic acid bacteria was carried out under low temperature for the preparation of Yogurt by using various food supplements like carrot, ground-nut and tomato juices. Methods: Various samples of Cow milk, Skimmed milk were processed along with nutrients like Carrot, ground nut and tomato juices with Tryptone glucose yeast extract agar (TGYA) at differe...

Pyruvate kinase (PYK) is a critical allosterically regulated enzyme that links glycolysis, the primary energy metabolism, to cellular metabolism. Lactic acid bacteria rely almost exclusively on glycolysis for their energy production under anaerobic conditions, which reinforces the key role of PYK in their metabolism. These organisms are closely related, but have adapted to a huge variety of nat...

BACKGROUND For some lactic acid bacteria higher biomass production as a result of aerobic respiration has been reported upon supplementation with heme and menaquinone. In this report, we have studied a large number of species among lactic acid bacteria for the existence of this trait. RESULTS Heme- (and menaquinone) stimulated aerobic growth was observed for several species and genera of lact...

Previous reports from this laboratory have shown that pantothenic acid is essential for the growth of every species of lactic acid bacteria tested (Snell et al., 1937). It has also been shown that while some species of lactic acid bacteria require riboflavin for growth, several do not (Snell and Strong, 1939). In a study of the activity of certain synthetic flavins, a close correlation was foun...

Lactic acid bacteria are among the powerhouses of the food industry, colonize the surfaces of plants and animals, and contribute to our health and well-being. The genomic characterization of LAB has rocketed and presently over 100 complete or nearly complete genomes are available, many of which serve as scientific paradigms. Moreover, functional and comparative metagenomic studies are taking of...

PURPOSE OF REVIEW Increasing knowledge, both experimental and clinical, supports the fact that early and aggressive enteral nutrition has the capacity to reduce superinflammation and prevent infections in severe acute pancreatitis. Clearly, the main role of enteral nutrition is to boost the immune system, and not, at least initially, to provide calories. Whereas enteral nutrition improves, pare...
