Ubiquitous late competence genes in Bacillus species indicate the presence of functional DNA uptake machineries [PDF]
, 2009 P>Natural competence for genetic transformation, i.e. the ability to take up DNA and stably integrate it in the genome, has so far only been observed in the bacterial kingdom (both in Gram-negative and Gram-positive species) and may contribute to ...

Metal ion activation and DNA recognition by the Deinococcus radiodurans manganese sensor DR2539
The FEBS Journal, Volume 291, Issue 15, Page 3384-3402, August 2024.The manganese sensor DR2539 from Deinococus radiodurans recognises the dr1709 promoter region, which consists of a 21 base pair pseudo‐palindrome binding two DR2539 monomers. Here, we identified four manganese binding sites and investigated protein‐DNA interactions, with critical nucleotides being probed.

Biotechnology and Bioengineering, Volume 121, Issue 4, Page 1365-1369, April 2024.Overexpression of endogenous multi‐copper oxidases mcoA and mcoC in Rhodococcus jostii RHA1 was found to enhance production of 2,4‐pyridine‐dicarboxylic acid from soda lignin by 2.5‐ and 3.5‐fold, respectively. This approach provides an opportunity to enhance titres of lignin‐derived bioproducts. Abstract To improve the titre of lignin‐derived pyridine‐

Isolation, purification, and characterization of xylanase produced by three species of bacillus under submerged fermentation conditions [PDF]
, 2016 This study focuses on the screening and identification of bacteria, which can produce alkaline xylanase at alkaline pH and high temperature. Bacterial isolates from enriched decaying soil, capable of hydrolyzing xylan were screened. Selected and purified

International Journal of Microbiology, Volume 2024, Issue 1, 2024.The goal of the study is to evaluate metabolic and morphological changes of the facultative alkaliphile Bacillus aequororis 5‐DB and the weakly alkali‐resistant B. subtilis ATCC 6633 in a wide pH range and at different NaCl concentrations. The alkaliphile B. aequororis 5‐DB is shown to have a broader general resistance to adverse factors (wide pH range,
