Gentlyase is a bacterial extracellular metalloprotease that is widely applied in cell culture and for tissue dissociation and that belongs to the family of thermolysin-like proteases. The structure of thermolysin has been known since 1972 and that of Bacillus cereus neutral protease since 1992. However, the structure determination of other Bacillus neutral proteases has been hindered by their t...

The diversity of dinitrogenase reductase gene (nifH) fragments in Paenibacillus azotofixans strains was investigated by using molecular methods. The partial nifH gene sequences of eight P. azotofixans strains, as well as one strain each of the close relatives Paenibacillus durum, Paenibacillus polymyxa, and Paenibacillus macerans, were amplified by PCR by using degenerate primers and were chara...

Diversity among 130 strains of Bacillus polymyxa was studied; the bacteria were isolated by immunotrapping from nonrhizosphere soil (32 strains), rhizosphere soil (38 strains), and the rhizoplane (60 strains) of wheat plantlets growing in a growth chamber. The strains were characterized phenotypically by 63 auxanographic (API 50 CHB and API 20B strips) and morphological features, serologically ...

2,3-butanediol (2,3-BDO) is a platform chemical that can be converted to wide array of products ranging from bio-based materials sustainable aviation fuel. This produced by variety microorganisms in fermentation processes. Challenges remain for high titer 2,3-BDO production during due several parameters, but controlling oxygen one the most relevant processing parameters ensure viable product ou...
