Weak solutions for a bioconvection model related to Bacillus subtilis [PDF]

Commun. Math. Sci. 12 (2014) 545-563, 2012
We consider the initial-boundary value problem for the coupled Navier-Stokes-Keller-Segel-Fisher-Kolmogorov-Petrovskii-Piskunov system in two- and three-dimensional domains. The problem describes oxytaxis and growth of Bacillus subtilis in moving water. We prove existence of global weak solutions to the problem.

TRANSFORMATION IN BACILLUS SUBTILIS

The Journal of General and Applied Microbiology, 1972
An apparatus which allows the continuous deproteinization of nucleic acid solutions, reducing manual work, for methods in which the deproteinizing reagent is constituted by a liquid phase not mixing with the aqueous phase containing nucleic acids, is described.

Prediction Stability in a data-based mechanistic model of sigmaF during sporulation in Bacillus subtilis [PDF]

arXiv, 2013
Mathematical modeling of biological networks can help to integrate a large body of information into a consistent framework, which can then be used to arrive at novel mechanistic insight and predictions. We have previously developed a detailed, mechanistic model for the regulation of {\sigma}F during sporulation in Bacillus subtilis. The model was based

The PDZ domain of the SpoIVB serine peptidase facilitates multiple functions [PDF]

, 2001
During spore formation in Bacillus subtilis, the SpoIVB protein is a critical component of the sigma (K) regulatory checkpoint. SpoIVB has been shown to be a serine peptidase that is synthesized in the spore chamber and which self-cleaves, releasing ...

Integrated impact of environmentally friendly extraction and recovery methods on almond oil quality: Insights from a lipidomic perspective

Journal of the American Oil Chemists' Society, EarlyView.
Abstract Although aqueous and enzymatic extractions are solvent‐free alternatives for extracting oil and proteins from almond flour, most of the extracted oil becomes entrapped in an emulsion and needs demulsification for recovery. To assess how extraction and demulsification methods impact yields and quality, a lipidomic approach was used to ...

Volatile compounds produced by Bacillus species alkaline fermentation of bambara groundnut (Vigna subterranean (L.) Verdc) into a dawadawa-type African food condiment using headspace solid-phase microextraction and GC × GC–TOFMS

International Journal of Food Properties, 2018
The reports on the volatile compounds of a dawadawa-type African food condiment produced from the alkaline fermentation of bambara groundnut (Vigna subterranea (L.) Verdc.) using Bacillus starter cultures are limited.

Emergence of Staphylococcus aureus Resistance to Antimicrobial Peptides Nisin, NZ2114 and Bacitracin Involves Multiple Phenotypic Changes

Animal Research and One Health, EarlyView.
The AMP‐induced mutant Staphylococcus aureus strain nzR showed increased resistance, five gene mutations, and decreased surface anion levels. AMPs affect the NDH‐2 protein encoded by ndh gene inhibiting the growth of S. aureus. The deletion of the ndh gene promotes the development of AMPs resistance.

A model of cell-wall dynamics during sporulation in Bacillus subtilis [PDF]

arXiv, 2017
To survive starvation, Bacillus subtilis forms durable spores. After asymmetric cell division, the septum grows around the forespore in a process called engulfment, but the mechanism of force generation is unknown. Here, we derived a novel biophysical model for the dynamics of cell-wall remodeling during engulfment based on a balancing of dissipative ...
