lactobacillus paraplantarum 11-1 isolated from rice bran pickles activated innate immunity and improved survival in a silkworm bacterial infection model.lactic acid bacteria (lab) have high immune system-stimulating activity and are considered beneficial for human health as probiotics in the gut. the innate immune system is highly conserved between mammals and insects. microbe-associated molecular patterns (e.g., peptidoglycan and β-glucan) induce cytokine maturation, which, in silkworm larvae, leads to muscle contraction. the purpose of this study is to find a novel probiotic by using silkworm muscle contraction assay. in the present study, we ...201728373863
diversity and evolutionary aspects of mucin binding (mucbp) domain repeats among lactobacillus plantarum group strains through comparative genetic analysis.mucin binding protein (mub) of lactobacillus plantarum- group (lpg) is considered as a potential marker gene due to its diversity and adherence property to host intestinal layer. we recently observed strain specific diversity in mub gene of lpg strains (n=8) and grouped them into type i, ii and iii based on the insertion and/or deletion of mucbp domain repeats (devi et al., 2016). the mub gene expression pattern noted by real-time pcr revealed 67.64 increased fold change in mtcc 9483 with four m ...201728442158
in vitro antifungal, probiotic, and antioxidant functional properties of a novel lactobacillus paraplantarum isolated from fermented dates in saudi arabia.fermented foods produced using dates are used in gulf countries as beneficial and healthful foods. the beneficial microbial flora in fermented dates contributes to maintaining the nutritional properties of dates by preventing the growth of spoilage fungi. here, we examined the antifungal, probiotic, and antioxidant properties of the novel lactobacillus strain d-3 isolated from fermented dates.201728480570
complete genome sequence of lactobacillus paraplantarum l-zs9, a probiotic starter producing class ii bacteriocins.lactobacillus paraplantarum l-zs9 is a probiotic starter isolated from fermented sausage and it is a great producer of class ii bacteriocins. to the best of our knowledge, this is the first complete sequenced genome of l. paraplantarum deposited in genbank database. the size of the complete genome of l. paraplantarum l-zs9 is 3,139,729 bp. the genomic sequence revealed that this strain includes 19 genes involved in class ii bacteriocins production and regulation. the information fill the gaps of ...201626853479
capability of exopolysaccharide-producing lactobacillus paraplantarum bgcg11 and its non-producing isogenic strain nb1, to counteract the effect of enteropathogens upon the epithelial cell line ht29-mtx.the putative protective role of the exopolysaccharide (eps)-producing lactobacillus paraplantarum bgcg11, and its non-eps-producing isogenic strain nb1, was tested upon ht29-mtx monolayers challenged with seven opportunistic pathogens. the probiotic strain lactobacillus rhamnosus lmg18243 (gg) was used as a reference bacterium. tested lactobacilli were able to efficiently reduce the attachment to ht29-mtx of most pathogens. lb. paraplantarum nb1 and lb. rhamnosus gg were more efficient reducing ...201528411984
exopolysaccharide production and ropy phenotype are determined by two gene clusters in putative probiotic strain lactobacillus paraplantarum bgcg11.lactobacillus paraplantarum bgcg11, a putative probiotic strain isolated from a soft, white, artisanal cheese, produces a high molecular-weight heteropolysaccharide, exopolysaccharide (eps)-cg11, responsible for the ropy phenotype and immunomodulatory activity of the strain. in this study, a 26.4-kb region originating from the pcg1 plasmid, previously shown to be responsible for the production of eps-cg11 and a ropy phenotype, was cloned, sequenced, and functionally characterized. in this region ...201525527533
paraplantaricin l-zb1, a novel bacteriocin and its application as a biopreservative agent on quality and shelf life of rainbow trout fillets stored at 4 °c.paraplantaricin l-zb1 was produced by lactobacillus paraplantarum l-zb1, which was isolated from the traditional china fermented sausage. in this work, paraplantaricin l-zb1 was used to maintain quality of rainbow trout fillets at 4 °c. rainbow trout fillets were left untreated (ck) or treated with 200 activity units (au)/ml paraplantaricin l-zb1 (p1), 400 au/ml paraplantaricin l-zb1 (p2) or 200 au/ml nisin (n). the treated samples were stored at 4 °c for up to 10 days, and the quality changes w ...201425178418
role of plnb gene in the regulation of bacteriocin production in lactobacillus paraplantarum l-xm1.homologues of plnb gene have been shown to participate in regulation of bacteriocin production through quorum sensing system in other organisms, to investigate the possible role of plnb gene in lactobacillus paraplantarum l-xm1, we cloned and insertionally inactivated the plnb gene. the plnb knockout mutant δplnb21 showed loss of bacteriocin production, its bac⁺ phenotype could not be restored even after the addition of plna. furthermore, reverse transcription-pcr analysis from total rna prepara ...201323276644
