Partial purification and characterization of a bacteriocin produced by Lactobacillus acidophilus

مجلة مركز بحوث التقنيات الاحيائية, 2013
Bacteriocin produced by Lactobacillus acidophilus was partially purified by ammonium sulfate precipitation 60% saturation. The bacteriocin exhibited activity of 320AU/ml against Serratia marcescens. Characterization of bacteriocin showed that its active

Aptamer‐mediated outer membrane destabilization overcomes low permeability resistance in Pseudomonas aeruginosa

The FEBS Journal, EarlyView.
DNA aptamers, Apt 60 and Apt 173, target the BamA protein to compromise outer membrane integrity in Pseudomonas aeruginosa, making it susceptible to Azithromycin, an antibiotic that is otherwise poorly effective due to the low‐permeability membrane.

Comprehensive and Comparative Transcriptional Profiling of the Cell Wall Stress Response in Bacillus subtilis

Molecular Microbiology, EarlyView.
Transcriptional profiling of the primary cell envelope stress response (CESR) of Bacillus subtilis exposed to a range of cell wall‐targeting antimicrobials, combining RNAseq and high‐resolution tiling arrays. We revealed the complexity of the CESR, the contribution of extracytoplasmic function sigma factors (ECFs) and two‐component signal transduction ...

Quorum sensing-controlled gene expression in lactic acid bacteria [PDF]

, 1998
Quorum sensing in lactic acid bacteria (LAB) involves peptides that are directly sensed by membrane-located histidine kinases, after which the signal is transmitted to an intracellular response regulator. This regulator in turn activates transcription of
