Lactobacillus plantarum strain B21 was isolated from Vietnamese sausage (nem chua) and demonstrated broad antimicrobial activity due to the production of bacteriocins. Here, we report the complete genome sequence of this strain (3,284,260 bp).
The esential role of -glutamine in microbial nutrition and metabolism has been well established (Waelsch, 1952). Recently Ayengar et al. (1951) have described in detail the stimulating effect of the amide on the utilization of i-glutamic acid by Lactobacillus arabinosus. However, almost no published data exist which deal with the influence of iisoglutamine on bacterial growth. We wish to descri...

AIM To determine whether Lactobacillus plantarum can modify the deleterious effects of tumor necrosis factor-alpha (TNF-alpha) on intestinal epithelial cells. METHODS Caco-2 cells were incubated with TNF-alpha alone or in the presence of L. plantarum. Transepithelial electrical resistance was used to measure epithelial barrier function. Interleukin 8 (IL-8) secretion by intestinal epithelial ...
The influence of pH on the type and concentration of metabolites produced from pyruvate by Lactobacillus plantarum ATCC 8014 was examined in pH-controlled fermentors at pH values of 4.5 to 6.5. Specific growth rates, cell dry weights, and diacetyl concentrations were highest at pH 5.5, with values of 0.78 h, 190 mg/liter, and 1.2 mM, respectively. While the conversion efficiency (millimoles of ...
کلبسیلا (klebsiella) باکتری گرم منفی و غیرمتحرکی هست که دارای کپسول پلی ساکاریدی می باشد. klebsiella pneumoniae از گونه های معروف آن و به دلیل خصوصیاتی مانند مقاومت آنتی بیوتیکی، از اهمیت بالایی برخوردار است. k. pneumoniae دارای پلاسمید های متعدد و حامل ژن های مقاومت به آنتی بیوتیک ها، بخصوص بتالاکتام ها، سفالوسپورین های نسل دوم و سوم می باشد. به کارگیری ترکیبات ضد میکروبی جدید که منجر به از بی...
Lactobacillus plantarum is one of the most versatile species extensively used in the food industry both as microbial starters and probiotic microorganisms. Several L. plantarum strains have been shown to produce different antimicrobial compounds such as organic acids, hydrogen peroxide, diacetyl, and also bacteriocins and antimicrobial peptides, both denoted by a variable spectrum of action. In...
Although it is clear that probiotics improve intestinal barrier function, little is known about the effects of probiotics on the aging intestine. We investigated effects of 10-week bacterial supplementation of Lactobacillus plantarum WCFS1, Lactobacillus casei BL23, or Bifidobacterium breve DSM20213 on gut barrier and immunity in 16-week-old accelerated aging Ercc1-/Δ7 mice, which have a median...
خمیرترش، یک قطعه خمیر از پخت قبلی میباشد که برای تولید نان با آرد، نمک و آب مخلوط و سپس ذخیره میشود. میکروارگانیسمهای اصلی خمیرترش، باکتریهای اسید لاکتیک و مخمرها هستند که نقش مهمی در بهبود طعم، بافت و ماندگاری فراوردههای نانوایی ایفا میکنند. در تحقیق حاضر، 7 نمونه خمیرترش از ییلاقهای ماسوله، همدان، نطنز، کیاسر، آمل، فومن جمعآوری و جهت انجام تحقیق استفاده گردید. باکتریهای اسید لاکتیک و...
In the past decade it has become clear that the lactic acid bacterium Lactobacillus plantarum occupies a diverse range of environmental niches and has an enormous diversity in phenotypic properties, metabolic capacity and industrial applications. In this review, we describe how genome sequencing, comparative genome hybridization and comparative genomics has provided insight into the underlying ...
