The induction of the heat shock response in Lactococcus lactis subsp. cremoris strain MG1363 was analysed at the RNA level using a novel RNA isolation procedure to prevent degradation. Cloning of the dnaJ and groEL homologues was carried out. Northern blot analysis showed a similar induction pattern for dnaK, dnaJ and groELS after transfer from 30 degrees C(More)
Indigenous fermented food products play an essential role in the diet of millions of Africans. Lactic acid bacteria (LAB) are among the predominant microbial species in African indigenous fermented food products and are used for different applications in the food and biotechnology industries. Numerous studies have described antimicrobial susceptibility(More)
The Bifidobacterium animalis subsp. lactis BB-12 gene BIF_00092, assigned to encode a β-d-xylosidase (BXA43) of glycoside hydrolase family 43 (GH43), was cloned with a C-terminal His-tag and expressed in Escherichia coli. BXA43 was purified to homogeneity from the cell lysate and found to be a dual-specificity exo-hydrolase active on(More)
The food industry is constantly striving to develop new products to fulfil the ever changing demands of consumers and the strict requirements of regulatory agencies. For foods based on microbial fermentation, this pushes the boundaries of microbial performance and requires the constant development of new starter cultures with novel properties. Since the use(More)
A 3,165-bp chromosomally integrated transposon, designatedTn3692, of the gram-positive strain Lactobacillus crispatus CHCC3692 contains an erm(B) gene conferring resistance to erythromycin at concentrations of up to 250 micrograms/ml. Loss of this resistance can occur spontaneously, but the rate is substantially increased by heat shock treatment. Heat shock(More)
In Salmonella typhimurium, different conformations of the pyrC and pyrD leader transcripts are produced as a result of nucleotide sensitive selection of the transcriptional start site. The CTP-initiated transcripts, synthesized at high intracellular CTP/GTP pool ratios (repressing conditions), have the potential of forming a stable secondary structure at(More)
The Bacillus sonorensis L12 draft genome sequence is approximately 4,647,754 bp in size with a G+C content of 45.2%. Over 86% of the genome contains protein-encoding genes, including several gene clusters for de novo biosynthesis of the nonribosomal lipopeptides iturin, bacitracin, and fengycin, which could mean that the strain exhibits antifungal effects.
