Highly alkalophilic Bacillus species, such as Bacillus clausii and Bacillus halodurans, produce more highly alkaline stable enzymes used in heavy-duty detergent formulations, such as Esperase produced by Novo Nordisk.

2011年5月6日 · Among the B. halodurans -specific genes are 10 sigma (σ) factors that may have a role in adaptation to alkaline environments. Moreover, the B. halodurans genome bears a very large number of transposase and recombinase genes (112 compared to 12 in B. subtilis).

A mannanase with interesting properties for the paper and detergent industry was characterized from Bacillus halodurans (Table 1). This enzyme displayed highest activity at 70 °C and pH 11.0 and was extremely resistant to detergents and high salt concentrations [ 22 ].

In this report we characterize the regulation of the tryptophan biosynthetic genes in B. halodurans and demonstrate that, as seen in B. subtilis, both the trpEDCFBA operon and pabA ( trpG) are regulated by TRAP in response to changes in tryptophan levels.

Historical synonyms: Bacillus alcalophilus subsp. halodurans Boyer et al., 1973 (the type strain), Bacillus lentus type lll Gordon and Hyde 1982. Rods, 0.5-0.6 x 3.0-4.0 µm, occuring in long chains even when sporulated.

2020年7月7日 · The OapB protein from B. halodurans binds the P13 region of OLE RNA with an affinity in the mid-picomolar range. This strong interaction is required for cells to exhibit the most severe sensitivity phenotypes when exposed to cold, short-chain alcohols, or slightly elevated Mg 2+ concentrations.

"A phylogenomic and comparative genomic framework for resolving the polyphyly of the genus Bacillus: Proposal for six new genera of Bacillus species, Peribacillus gen. nov., Cytobacillus gen. nov., Mesobacillus gen. nov., Neobacillus gen. nov., Metabacillus gen. nov. and Alkalihalobacillus gen. nov."

2000年11月1日 · Bacillus halodurans C-125 requires Na + for growth under alkaline conditions. The presence of sodium ions in the surrounding environment has been proved to be essential for effective solute transport through the cytoplasmic membrane of C-125 cells.

Bacillus halodurans is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Bacillus.

Haloduracin is a two-component antibiotic consisting of prepeptides hal A1 and hal A2, which undergo posttranslational modification, and act in synergy. Haloduracin is produced by alkalophilic Bacillus halodurans.
