Colonization of plant roots by Bacillus subtilis is mutually beneficial to plants and bacteria. Plants can secrete up to 30% of their fixed carbon via root exudates, thereby feeding the bacteria, and in return the associated B. subtilis bacteria provide the plant with many growth-promoting traits. Formation of a biofilm on the root by matrix-producing B. subtilis is a well-established requireme...

Some scholars caution that long-term ad libitum feeding with probiotic fermented food poses potential health risks to baby animals. We conducted a feeding experiment to investigate the influence of ad libitum feeding of pre-and post-weaned piglets with a Bacillus subtilis fermented diet on the gut microbiome, gut metabolomic profiles, bile acid metabolism, proinflammatory cytokines and faecal c...

Bacillus strains were isolated from the rhizosphere of cereals in order to be used as natural biocontrol agents (BCAs). They were screened for antagonism in vitro against various test micro-organisms. The isolates showing antagonism were identified to species level. A combination of techniques was employed for the isolation of Bacillus species. Using the direct method, only one of the 25 isolat...

Biosurfactants are amphiphilic compounds produced by various bacteria and fungi which reduce surface and interfacial tension. Oil contaminated soil were collected from four different automobile shop in Mayiladuthurai, Tamilnadu, India. Bacillus subtilis and Pseudomonas aeruginosa were isolated and identified from these four samples and these were screened for biosurfactants production using veg...

A total of 720 newly-hatched Arbor Acres broilers were selected to investigate the effects of fructooligosaccharide (FOS) and B. subtilis on performance and microbial gut concentration in broilers. The result indicated that dietary supplementation with FOS or Bacillus in comparison to an antibiotic had selective effects on increasing caecal concentration of beneficial bacteria such as Lactobaci...

Bacillus subtilis is currently used as an oral probiotic. We examined two commercial B. subtilis probiotic preparations, Enterogermina and Biosubtyl. Surprisingly, physiological and genetic characterization of the bacteria contained in each of these preparations has shown that neither contains B. subtilis.

conclusions this study indicated that some bacillus species have the potential to produce antimicrobial compounds which can be used to control microbial infections. results the identified bacillus species included b. cereus (86.6%), b. subtilis (6.6%), b. thuringiensis (3.3%), and b. pumilus (3.3%). evaluation of the antimicrobial activity of the extracted compounds was carried out against five...

In the present study, we evaluated the antibacterial activity in the leaf extracts of Mentha piperita L. against pathogenic bacteria like Bacillus subtilis, Pseudomonas aureus, Pseudomonas aerogenosa, Serratia marcesens and Streptococcus aureus. The aqueous as well as organic extracts of the leaves were found to posses strong antibacterial activity against a range of pathogenic bacteria as reve...

Cellulase-producing bacteria were isolated from soil and identified as Pseudomonas fluorescens, Bacillus subtilIs, E. coli, and Serratia marcescens. Optimization of the fermentation medium for maximum cellulase production was carried out. The culture conditions like pH, temperature, carbon sources, and nitrogen sources were optimized. The optimum conditions found for cellulase production were 4...
