In this research, antagonistic activity of two Bacillus species isolated from digestive tract of marine fish and culture pond of sea cucumber was studied. The inhibitory activity of Bacillus spp. isolates against some common pathogenic bacteria of fish was assessed using the agar diffusion method. The strain of B. subtilis G024 exhibited antimicrobial activity against Vibrio anguillarum, V. har...

Bacillus amyloliquefaciens HB-26, a Gram-positive bacterium was isolated from soil in China. SDS-PAGE analysis showed this strain secreted six major protein bands of 65, 60, 55, 34, 25 and 20 kDa. A bioassay of this strain reveals that it shows specific activity against P. brassicae and nematode. Here we describe the features of this organism, together with the draft genome sequence and annotat...

background: today a large number of bacterial amylases are available commercially in industry. the goal of the present study was purification and biochemical characterization of an extracellular thermostable alkaline α-amylase from the novel moderately halophilic, bacillus persicus from the aran-bidgol, iran.   methods : purification of enzyme, was carried out by acetone precipitation, ultrafil...

Two selected case studies on process development will be discussed: one is on the enantiocontrolled synthesis of (S)-3-hydroxytetradecanoic acid (2), an intermediate of ONO-4007 (3) possessing anti-tumour activity, which employs double homologation of (S)-epichlorohydrin (ECH) (1b) with its termini being differentiated. The other is on the enantioselective access to N-4-cyano-3-trifluoromethylp...

Bacillus amyloliquefaciens subsp. plantarum UCMB5033 is of special interest for its ability to promote host plant growth through production of stimulating compounds and suppression of soil borne pathogens by synthesizing antibacterial and antifungal metabolites or priming plant defense as induced systemic resistance. The genome of B. amyloliquefaciens UCMB5033 comprises a 4,071,167 bp long circ...

Harmful algal blooms, caused by massive and exceptional overgrowth of microalgae and cyanobacteria, are a serious environmental problem worldwide : In the present study, we looked for Bacillus strains with sufficiently strong anticyanobacterial activity to be used as biocontrol agents. Among 24 strains, Bacillus amyloliquefaciens FZB42 showed the strongest bactericidal activity against Microcys...

Bacillus amyloliquefancies CH51 isolated from cheonggukjang, a traditional Korean fermented soy food, has strong fibrinolytic activity and produces several fibrinolytic enzymes. Among four different growth media, tryptic soy broth was the best in terms of supporting cell growth and fibrinolytic activity of this strain. A protein with fibrinolytic activity was partially purified from the culture...

Sporulation is a survival strategy, adapted by bacterial cells in response to harsh environmental adversities. The adaptation potential differs between strains and the variations may arise from differences in gene regulation. Gene networks are a valuable way of studying such regulation processes and establishing associations between genes. We reconstructed and compared sporulation gene co-expre...

Alpha amylase production using microbial source and solid state fermentation has been conducted for past few years in search of thermostable enzyme. Owing to the prolific use of thermostable alpha amylase in various industries like paper, food, detergent, brewing and starch liquefaction process, the production of alpha amylase is still going on. In the present work, Bacillus subtilis (ATCC 6633...
