The acid-stress response in Lactobacillus sanfranciscensis CB1
Article Abstract:
The acid-stress response in Lactobacillus sanfranciscensis CB1, an important sourdough lactic acid bacterium, is discussed. Attention is given to isolation of constitutively acid-tolerant mutants and improved growth properties of mutant and acid-adapted cells in restrictive environmental conditions. Modification of protein levels after acid adaptation is covered as is identification of mutants of DnaJ, SnaK, GroES, and GrpEproteins, the N-terminal sequencing of proteins and their homology with previously identified stress proteins, and use of mutants to improve sourdough fermentation in certain conditions.

A mutation that affects fibril protein, development, cohesion and gene expression in Myxococcus xanthus
Article Abstract:
A study was conducted on a mutation that influences fibril protein, development, cohesion and gene expression in the social prokaryote, Myxococcus xanthus. The findings indicate that the extracellular matrix fibrils may not play a role in later developmental gene expression. Moreover, the results show that intact fibrils may act early in development to promote close cell proximity for signal exchange.

Characterization and production of amylovorin L471, a bacteriocin purified from Lactobacillus amylovorus DCE 471 by a novel three-step method
Article Abstract:
Amylovorin L471, a bacteriocin purified from Lactobacillus amylovorus DCE 471 is discussed with information about its purification by a novel three-step method with only one chromatographic step. Adsorption of the bacteriocin molecules to the producing cells is prevented by ethanol.
