Sporulation of Bacillus subtilis in Continuous Culture
Sporulation of Bacillus subtilis 168 was studied in chemostat cultures. Sporulation occurred at high frequency under limitation of growth by glucose or the nitrogen source in minimal medium, whereas rates of sporulation were low for Mg'+, phosphate, citrate, or tryptophan limitation. Sporulation was found at all growth rates tested, and the incidence of spores increased with decrease in growth ...

متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Biofilm formation and sporulation in Bacillus subtilis
Biofilms are architecturally complex communities of microorganisms in which the cells are held together by an extracellular matrix, typically containing exopolysaccharides (EPSs), proteins and some nucleic acids. Our understanding of the molecular mechanisms involved in biofilm formation has increased tremendously in recent years. However, information about biofilm formation and sporulation is ...
متن کاملUnmasking novel sporulation genes in Bacillus subtilis.
The Bacillus subtilis transcription factor sigma(E) directs the expression of a regulon of 262 genes, but null mutations in only a small fraction of these genes severely impair sporulation. We have previously reported that mutations in seven sigma(E)-controlled genes cause a mild (2- to 10-fold) defect in sporulation. In this study, we found that pairwise combinations of some of these seven mut...
