Species from the Burkholderia cepacia complex (Bcc) share a canonical LuxI/LuxR quorum sensing (QS) regulation system named CepI/CepR, which mainly relies on the acyl-homoserine lactone (AHL), octanoyl-homoserine lactone (C8-HSL) as signaling molecule. Burkholderia ambifaria is one of the least virulent Bcc species, more often isolated from rhizospheres where it exerts a plant growth-promoting ...

More than 30 years ago microbiologists found a way to induce luminescent bacteria to emit light prematurely. By adding cell-free culture fluid from a bright bioluminescent culture at high cell density to a nonluminous low-cell-density culture, they were able to eliminate the characteristic lag in bioluminescence (5, 12, 16). Nealson et al. proved that the “light switch” that controls the biolum...

in view of the fundamental role of genetics in development of obesity, the present study aimed to investigate the single nucleotide polymorphism of some obesity-related genes among a subset of obese women living in tabriz, iran. for this purpose, 70 eligible obese women (aged 18-45 years) were genotyped for the uncoupling protein-1 (ucp-1) -3826a>g, ß3-adrenergic receptor (ß3adr) trp64arg, lept...

The Pandian deposit is a newly discovered contact metasomatic skarn magnetite found in the Cainozoic super-thick overburden on northwest margin of Luxi Uplift (LXU). Presently, horizontal scale delineated by potential field (gravity and magnetic method) has shown giant for ore deposits, mapping ore-controlling structures vertical becomes primary task metallogenic prediction. In our study, wide-...
