چکیده

The complete nucleotide sequence (2389 bp) of the cryptic plasmid pLF1311 from Lactobacillus fermentum VKM1311 was determined. DNA sequence analysis revealed the putative coding regions for a replicative protein (RepB), its repressor (RepA) and double-stranded (dso) and single-stranded (sso) origins. pLF1311 belongs to the pE194 family of rolling circle-replicating plasmids. A derivative of pLF1311 that contains the cat gene of plasmid pC194 of Staphylococcus aureus and the oriT of RP4 was constructed and transferred by conjugative mobilization from Escherichia coli to various Gram-positive bacteria. The stable maintenance of this derivative was shown in some strains of Lactobacillus, Lactococcus, Enterococcus and Bacillus under non-selective conditions.

Expression of bacillar glutamyl endopeptidase genes in Bacillus subtilis by a new mobilizable single-replicon vector pLF.

The pLF1311 natural plasmid from Lactobacillus fermentum 1311 was used to construct a single-replicon vector suitable for rapid cloning in a wide range of gram-positive hosts and Escherichia coli. The new vector is capable of conjugative mobilization from E. coli to various hosts by conjugal transfer. The final vector (3.4 kb) showed a high segregational and structural stability and a high copy...

Expression of a streptococcal glucosyltransferase as a fusion to a solute-binding protein in Lactobacillus fermentum BR11.

BspA is a non-covalently anchored cystine-binding protein from Lactobacillus fermentum BR11. It has previously been used to present antigens derived from infectious organisms on the L. fermentum BR11 cell surface. In this study, the capacity of BspA to present a very large polypeptide was tested. A temperature sensitive plasmid was constructed that encodes a 175-kDa chimeric protein consisting ...

Protective Effect of Lactobacillus fermentum on Lead-induced Hematological and Body Weight Alterations in Rats

Background: Lead is known to be a highly toxic heavy metal which has a wide range of effect on human health. It has been proven that probiotics are able to bind heavy metals and remove them from the environment. In this study, the effect of Lactobacillus fermentum (L. fermentum) and its cytoplasmic extract were investigated on the hematological and body weight parameters in lead exposed rats. ...
