High‐level production of melanin by a novel isolate of Streptomyces kathirae
Abstract
Forty‐five bacterial strains that produced diffusive pigments were isolated from 40 soil samples. Maximum pigment production was from a Streptomyces kathirae strain designated SC‐1. The diffused pigment was characterized by UV–visual and infrared spectroscopy, MS and 1H nuclear magnetic resonance imaging, and was confirmed as melanin. This may be the first report of melanin production by S. kathirae. To enhance melanin production, the culture medium was optimized by conducting a series of batch fermentations in a defined medium, and the results were analysed statistically using a response surface method. Th...

Deinococcus radiodurans can interfere with quorum sensing by producing an AHL‐acylase and an AHL‐lactonase
We report here the presence of a member of each group of enzymes in the extremophile bacterium Deinococcus radiodurans. Co‐occurrence of both enzymes in a single species increases the chance of inactivating foreign AHL signals under different conditions. We demonstrate that both enzymes are able to degrade the quorum‐sensing molecules of various pathogens subsequently affecting virulence gene expression. These studies add the quorum‐quenching enzymes of D. radiodurans to the list of potent quorum‐quenchers and highlight the idea that quorum quenching could have evolved in some bacteria as a strategy to gain a comp...

Role of protease maturation lipoprotein in osmoadaptation of Streptococcus mutans
In this study, we showed that S. mutans utilizes K+ for osmoadaptation, in which protease maturation lipoprotein (PrtM) plays an important role. Although growth of the wild‐type strain was impaired in a hyperosmotic medium [brain heart infusion (BHI) containing 0.3 M NaCl] compared with that in an unmodified BHI, the prtM mutant grew much more poorly in 0.3 M NaCl BHI. Comparison of growth behavior in the hyperosmotic medium supplemented with different osmoprotectants revealed that only the addition of K+ allowed the bacteria to overcome the impairment of growth caused by the high osmolality. These results suggest tha...

The Cyclic AMP‐Binding Protein CbpB in Brucella melitensis and its role in cell envelope integrity, resistance to detergent and virulence
Abstract
Brucella melitensis possesses an operon with two components: the response regulator OtpR and a putative cAMP‐dependent protein kinase regulatory subunit encoded by the BMEI0067 gene. In the previous study, the function of OtpR has been studied, while little is known about the function of the BMEI0067 gene. Using a bioinformatics approach, we showed that the BMEI0067 gene encodes an additional putative cAMP‐binding protein, which we refer to as CbpB. Structural modeling predicted that CbpB has a cAMP‐binding protein (CAP) domain and is structurally similar to eukaryotic protein kinase A regulatory subunits. H...
