Carotenoid production in Lactobacillus plantarum.

The effects of Lactobacillus plantarum on chemical composition, rumen degradability, in vitro gas production and energy content of whole-plant corn ensiled at different stages of maturity

This study was carried out to determine the effects of Lactobacillus plantarum on chemical compositionand nutritive value of whole-plant corn (WPC) ensiled at different stages of maturity. Based on local routinepractice, WPC was harvested at three stages of maturity as follows: (1) two weeks before routine harvestingtime; (2), one week before routine harvesting time and (3), routine harvesting ...

Studies concerning the Production of Lactobacilli Acid in Lactobacillus Plantarum

Coculture with specific bacteria enhances survival of Lactobacillus plantarum NC8, an autoinducer-regulated bacteriocin producer, in olive fermentations.

Bacteriocin production in Lactobacillus plantarum NC8 is activated by coculture with specific bacteriocin production-inducing bacterial strains. The system is further regulated by a three-component regulatory system involving a specific autoinducer peptide (PLNC8IF). We have used L. plantarum NC8 as a starter culture in Spanish-style green olive fermentations and examined the influence of cocul...

A selective differential medium for Lactobacillus plantarum.

The quantification of exogenous lactobacilli in faecal samples is frequently required for the evaluation of the intestinal colonization by probiotic bacteria. In this study, a selective and differential medium, designated LPSM, was developed for the culture of exogenous Lactobacillus plantarum. In quantitative assays, LPSM showed a sensitivity similar to those of enriched and Lactobacillus-adap...

Induction of plantaricin production in Lactobacillus plantarum NC8 after coculture with specific gram-positive bacteria is mediated by an autoinduction mechanism.

Plantaricin NC8 (PLNC8), a coculture-inducible two-peptide bacteriocin from Lactobacillus plantarum NC8, has recently been purified and genetically characterized. Analysis of an 8.1-kb NC8 DNA region downstream of the PLNC8 operon revealed the presence of at least four operons involved in bacteriocin production, showing high homology to the plantaricin cluster in L. plantarum C11. However, we f...
