Quorum Sensing in Microbial Virulence
Cell-to cell communication occurs via a signaling pathway referred to as quorum sensing. There are four main types of these systems according to the chemical nature of signal molecules used by microorganisms to elicit expression of target genes in response to environmental stimuli or need of microbial communities. Type I system acts by using acyl homoserine lactones as signals to trigger the ex...
متن کاملHow Quorum Sensing Connects Sporulation to Necrotrophism in Bacillus thuringiensis
Bacteria use quorum sensing to coordinate adaptation properties, cell fate or commitment to sporulation. The infectious cycle of Bacillus thuringiensis in the insect host is a powerful model to investigate the role of quorum sensing in natural conditions. It is tuned by communication systems regulators belonging to the RNPP family and directly regulated by re-internalized signaling peptides. On...
متن کاملGenome and transcriptome analysis of surfactin biosynthesis in Bacillus amyloliquefaciens MT45
Natural Bacillus isolates generate limited amounts of surfactin (<10% of their biomass), which functions as an antibiotic or signalling molecule in inter-/intra-specific interactions. However, overproduction of surfactin in Bacillus amyloliquefaciens MT45 was observed at a titre of 2.93 g/l, which is equivalent to half of the maximum biomass. To systemically unravel this efficient biosynthetic ...
متن کاملIdentification of a quorum-sensing signal molecule in the facultative intracellular pathogen Brucella melitensis.
Brucella melitensis is a gram-negative alpha2-proteobacterium responsible for abortion in goats and for Malta fever in humans. This facultative intracellular pathogen invades and survives within both professional and nonprofessional phagocytes. A dichloromethane extract of spent culture supernatant from B. melitensis induces bioluminescence in an Escherichia coli acyl-homoserine lactone (acyl-H...
متن کاملDifferential Proteomics Analysis of Bacillus amyloliquefaciens and Its Genome-Shuffled Mutant for Improving Surfactin Production
Genome shuffling technology was used as a novel whole-genome engineering approach to rapidly improve the antimicrobial lipopeptide yield of Bacillus amyloliquefaciens. Comparative proteomic analysis of the parental ES-2-4 and genome-shuffled FMB38 strains was conducted to examine the differentially expressed proteins. The proteome was separated by 2-DE (two dimensional electrophoresis) and anal...
