Spores from a number of different Bacillus species are currently being used as human and animal probiotics, although their mechanisms of action remain poorly understood. Here we describe the isolation of 237 presumptive gut-associated Bacillus spp. isolates that were obtained by heat and ethanol treatment of fecal material from organically reared broilers followed by aerobic plating. Thirty-one...

In order to select phytotoxin producing rhizobacteria to control weed plants, twenty five bacterial strains previously isolated from the rhizospheres of various plants were grown in a liquid medium and, after cell removal by centrifugation, the liquid phases were freeze-dried and the products were extracted with ethyl acetate/methanol. The extracts were concentrated to dryness under vacuum and ...

a soil bacterium capable of degrading chitin on chitin agar plates was isolated and identified as bacillus pumilus isolate u5 on the basis of 16s rdna sequence analysis. in order to optimize culture conditions for chitinase production by this bacterium, a two step approach was employed. first, the effects of several medium components were studied using the plackett-burman design. among various ...

In the soil environment, Bacilli can affect nematode development, fecundity and survival. However, although many Bacillus species can kill nematodes, the virulence mechanisms Bacilli utilize remain unknown. In this study, we collected 120 strains comprising 30 species across the Bacillaceae and Paenibacillaceae families of the Bacillales order and measured their nematicidal activities in vitro....

In the present study, 12 aerobic bacterial strains were isolated from the common effluent treatment plant (CETP) of tannery industries and identified as Alcaligenes sp. (FJ55942), Pantoea sp. (FJ55943), Bacillus megaterium (FJ55944), B. marisflavi (FJ55945), B. subtilis (FJ55946), B. megaterium (FJ55947), B. cereus (FJ55948), B. pumilus (FJ55949), Pseudomonas sp. (FJ55950), Bacillus sp. (FJ5595...

Background: The extracellular xylanase secreted by microorganisms is a hydrolytic enzyme, which arbitrarily cleaves the β-1, 4 backbone of the polysaccharide xylan; an enzyme used in the food processing, bio-pulping and bio-bleaching. The commercial production of the xylanase is limited because of a higher cost involvement, which can be overcome by the cost-effective production...

This investigation was conducted to evaluate the antimicrobial effectiveness of agar disc diffusion method and determine inhibition zone Curcuma amada (CA) rhizome extracts (petroleum ether, dichloromethane, chloroform) against 12 bacterial species 4 fungal species. The zones were compared those Ciprofloxacin Griseofulvin for antibacterial antifungal activities, respectively. findings revealed ...
