The experiment aimed to specifically monitor the passage of lactobacilli in vivo after oral administration. The green fluorescent protein (GFP) gene was cloned downstream from the constitutive p32 promoter from L. lactis subsp. cremoris Wg2. The recombinant expression vector, pLEM415-gfp-p32, was electroporated into Lactobacillus plantarum (L. plantarum) isolated from goat. Green fluorescent pr...

Fumonisin B1 (FB1), a mycotoxin produced by Fusarium species is a predominant Group 2B carcinogen occurring in maize and maize-based poultry feeds. It is shown to be nephrotoxic, hepatotoxic, neurotoxic, and immunosuppressing in animals. In this study, we report the ameliorating effects of a probiotic strain, Lactobacillus plantarum MYS6 on FB1-induced toxicity and oxidative damage in broilers....

BACKGROUND Probiotics can be used to stimulate or regulate epithelial and immune cells of the intestinal mucosa and generate beneficial mucosal immunomodulatory effects. Beneficial effects of specific strains of probiotics have been established in the treatment and prevention of various intestinal disorders, including allergic diseases and diarrhea. However, the precise molecular mechanisms and...

Introduction: Anticancer effects of Lactobacillus acidophilus, as a probiotic bacterium, have been indicated in several studies. There are common therapeutic options for bladder cancer treatment; however, their side effects and recurrence of disease are considerable. Therefore, complementary medication is essential and it must be safe and effective. In the present research, we assessed the anti...

As a rational approach to the genetic development of a stable lysine overproducing strain of Lactobacillus plantarum for the fermentation of 'ogi', a Nigerian fermented cereal porridge, regulation of lysine biosynthesis in this species was investigated. Spontaneous lysine overproducing mutants of Lact. plantarum were obtained and their aspartokinase activities compared with those of wild-type s...

Lactobacillus plantarum is frequently found in the fermentation of plant-derived food products, where hydroxycinnamoyl esters are abundant. L. plantarum WCFS1 cultures were unable to hydrolyze hydroxycinnamoyl esters; however, cell extracts from the strain partially hydrolyze methyl ferulate and methyl p-coumarate. In order to discover whether the protein Lp_0796 is the enzyme responsible for t...

the ability of uropathogenic e. coli (upec) to cause symptomatic uti is associated with the expression of a variety of virulence factors. biofilm formation enables upec to resist the flow of urine and increases its tolerance to antimicrobials and the host immune response. the measurement of biofilm formation in vitro is affected by the type of culture medium used. the aim of this study was to e...
