The changes of the composition of growing medium and the fatty acid composition of Bacillus subtilis PO270, a bacterium isolated from the wheat rhizosphere, was evaluated during different phases of growth. During growth alkalinity reaction of medium was observed and in late stationary phase of growth the release of proteins and phenolic acids from cells was observed. Twenty six fatty acids were detected...
Studies of α-amylase production by Bacillus subtilis (CM3) isolated earlier from cow dung microflora, were carried out. The optimum temperature, pH and incubation period for amylase production were 50-70°C, 5.0-9.0 and 36 h, respectively. Enzyme secretion was very similar in the presence of any of the carbon sources tested (soluble starch, potato starch, cassava starch, wheat flour, glucose, fructose,...
Bacillus subtilis strains (CM1-CM5) isolated from culturable (cowdung microflora were investigated for indole-3-acetic acid (IAA) production in nutrient broth (NB). All the strains tested produced IAA in NB; albeit in very low concentrations (0.09-0.37 mg/l). The addition of L-tryptophan (0.1-1.0 g/l) into NB substantially enhanced IAA production (6.1-31.5 folds) indicating that L-tryp-tophan was...
Bacillus subtilis EAG-2 strain isolated from an ornamental plant nursery produced a highly active extracellular protease. It was purified to apparent homogeneity by successive purification steps. The SDS-gel of purified protease revealed a single band of 27 KDa on 10% polyacrylamide gel. Proteolytic activity was confirmed by using two different zymographic methods. Interestingly, the enzyme showed...
As a continuation of our research on the biological activity of undecan-x-ones (x = 2-4), their antimicrobial activity towards bacteria Escherichia coli and Bacillus subtilis, yeast Candida mycoderma and mould Aspergillus niger. was investigated. The population viability of the tested microbial strains in the presence of undecan-x-ones was determined by the impedimetric and agar disc diffusion methods...
In this study the effect of bean tempeh on the growth of Bacillus subtilis, Escherichia coli, Lactobacillus acidophilus and Lactobacillus paracasei bacteria was investigated. Antibacterial activity was observed only in relation to the bacteria Bacillus subtilis. The effect of tempeh products on human intestinal microflora was also assessed. Bean and soy tempeh were culinarily processed and next digested...
