the removal of disulfide oil (dso) from contaminated soil was studied by the bioremediation method and the influence of electrokinetic on the bioremediation process was investigated. the bacillus subtilis strain was used in the bioremediation process. the effects of humidity, time and dso concentration in soil was studied. the experimental results for the bioremediation of dso show, the removal...

In this study, we have identified a bacterium that can inhibit the growth of Staphylococcus aureus, and further analyzed its antibacterial activity and other biological characteristics and laid the foundation for its future application. Through isolation and culture of the unknown bacteria, the culture characteristics, morphology observation, biochemical test, preliminary antibacterial test, 16...

. From coastal ecosystems of the Dead Sea (vertical steep gorge around of the Dead Sea, clay-salt plain and a black highly mineralized muds) Bacillus licheniformis, B.subtilis subsp. subtilis, Bacillus sp., Staphylococcus hominis strains have been isolated. All strains grew at 0-10 % of NaCl in medium, in a range of 20-50°С. Resistance to UV has been revealed in all the investigated bacteria. L...

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...

Abstract Background This study aimed to investigate the rhizosphere bacterial isolates’ antagonistic property against soil-borne fungal phytopathogen, Sclerotium rolfsii Sacc. ( Athelia (Curzi) Tu & Kimbrough). The chemical control of disease caused by S . is economically and environmentally unsustainable, therefore, a bio-control agent in form rhizospheric bacteria gaining importance. Main...

Although several strains of B. subtilis with antifungal activity have been isolated worldwide, to date there are no published reports regarding the isolation of a native B. subtilis strain from strawberry plants in Mexico. A native bacterium (Bacillus subtilis 21) demonstrated in vitro antagonistic activity against different plant pathogenic fungi. Under greenhouse conditions, it was shown that...

Many different systems of bacterial interactions have been described. However, relatively few studies have explored how interactions between different microorganisms might influence bacterial development. To explore such interspecies interactions, we focused on Bacillus subtilis, which characteristically develops into matrix-producing cannibals before entering sporulation. We investigated wheth...

A cloned chemotaxis operon has been characterized. Thirteen representative che mutations from different complementation groups were localized on the physical map by recombination experiments. The use of integration plasmids established that at least 10 of these complementation groups within this locus are cotranscribed. An additional three complementation groups may form part of the same transc...
