Optimization of nutritional and non - nutritional factors involved for production of antimicrobial compounds from Lactobacillus pentosus SJ65 using response surface methodology
Bacteriocins from lactic acid bacteria are ribosomal synthesized antibacterial proteins/peptides having wide range of applications. Lactobacillus pentosus SJ65, isolated from fermented Uttapam batter (used to prepare south Indian pan cake), produces bacteriocin having a broad spectrum of activity against pathogens. Optimization studies are of utmost important to understand the source of utiliza...
متن کاملFermentation of ribose-C14 by Lactobacillus pentosus.
In studies (l-3) on the synthesis in vivo of ribose by the tracer technique, it was desirable to have a rapid means of degrading the pentose for determination of the Cl4 distribution. The fermentation of pentose by Lactobacillus pentosus 124-2 seemed suitable for this purpose. Fred et al. (4) showed that this organism produces 1 mole each of lactic and acetic acids per mole of pentose utilized....
متن کاملSafety assessment of a new strain of Lactobacillus pentosus (IBRC=11143) as a candidate probiotic
Background: It is believed that the consumption of an adequate amount of live lactic acid bacteria (as probiotic) may improve the health of their host. Many strains of lactic acid bacteria are generally considered to be safe. However, some strains of these bacteria have shown some adverse effects. Objectives: This study aimed to investigate the safety of a new strain of Lactobacillus pentosus ...
متن کاملRegulation of expression of the Lactobacillus pentosus xylAB operon.
The xylose cluster of Lactobacillus pentosus consists of five genes, two of which, xylAB, form an operon and code for the enzymes involved in the catabolism of xylose, while a third encodes a regulatory protein, XylR. By introduction of a multicopy plasmid carrying the xyl operator and by disruption of the chromosomal xylR gene, it was shown that L. pentosus xylR encodes a repressor. Constituti...
متن کاملFunctional expression in Lactobacillus plantarum of xylP encoding the isoprimeverose transporter of Lactobacillus pentosus.
The xylP gene of Lactobacillus pentosus, the first gene of the xylPQR operon, was recently found to be involved in isoprimeverose metabolism. By expression of xylP on a multicopy plasmid in Lactobacillus plantarum 80, a strain which lacks active isoprimeverose and D-xylose transport activities, it was shown that xylP encodes a transporter. Functional expression of the XylP transporter was shown...
