Two methods for isolation of endophytic and edaphic Bacillus spp. from sugarcane fields
Arquivos do Instituto Biológico, 2018 : Bacillus has been widely studied and used for the control of pests and diseases. The adapted protocol proposed by POLANCZYK (2004) proved to be more efficient than the one by the World Health Organization (WHO, 1985) to isolate edaphic strains of ...

alpha-helix E of Spo0A is required for sigma(A)- but not for sigma(H)-dependent promoter activation in Bacillus subtilis [PDF]
, 2004 At the onset of endospore formation in Bacillus subtilis, the DNA binding protein Spo0A activates transcription from two types of promoters. The first type includes the spoIIG and spoIIE promoters, which are used by sigma(A)-RNA polymerase, whereas the ...

Evaluating the capacity of human gut microorganisms to colonize the zebrafish larvae (Danio rerio) [PDF]
, 2018 Indexación: Scopus.In this study we evaluated if zebrafish larvae can be colonized by human gut microorganisms. We tested two strategies: (1) through transplantation of a human fecal microbiota and (2) by successively transplanting aerotolerant anaerobic

Isolation and characterization of a microorganism that produces biosurfactants in corn steep water
CyTA - Journal of Food, 2019 In this work a Bacillus strain with capacity to produce biosurfactants was isolated from commercial corn steep water (CSW). The identification of this bacterium was based on phenotypic characteristics.

Molecular mechanisms of adaptation of the moderately halophilic bacterium Halobacillis halophilus to its environment [PDF]
, 2013 The capability of osmoadaptation is a prerequisite of organisms that live in an environment with changing salinities. Halobacillus halophilus is a moderately halophilic bacterium that grows between 0.4 and 3 M NaCl by accumulating both chloride and ...

Crystallization of the regulatory and effector domains of the key sporulation response regulator Spo0A [PDF]
, 1999 The key response-regulator gene of sporulation, spo0A, has been cloned from Bacillus stearothermophilus and the encoded protein purified. The DNA-binding and phospho-acceptor domains of Spo0A have been prepared by tryptic digestion of the intact protein ...

Microbial dormancy in the marine subsurface: Global endospore abundance and response to burial
Science Advances, 2019 Bacterial endospores are dominant members of the marine deep biosphere. Marine sediments host an unexpectedly large microbial biosphere, suggesting unique microbial mechanisms for surviving burial and slow metabolic turnover.
