Clostridium perfringens can induce necrotic enteritis of chickens, which causes large economic losses every year. Bacillus licheniformis, a probiotic, can inhibit the growth of pathogenic bacteria such as Clostridium perfringens, thereby improving the health status of chickens. However, from a microbial ecology perspective, the mechanisms by which alterations to the gut microbiota improve healt...

Drought stress is one of the major yield affecting factor for pepper plant. The effects of PGPRs were analyzed in relation with drought resistance. The PGPRs inoculated pepper plants tolerate the drought stress and survived as compared to non-inoculated pepper plants that died after 15 days of drought stress. Variations in protein and RNA accumulation patterns of inoculated and non-inoculated p...

The membrane penicillinases of Bacillus licheniformis and Bacillus cereus are lipoproteins with N-terminal glyceride thioether modification identical to that of the Escherichia coli outer membrane lipoprotein. They are readily labeled with [3H]palmitate present during exponential growth. At the same time, a few other proteins in each organism become labeled and can be detected by fluorography a...

Pyrithione (2-mercaptopyridine-N-oxide; Omadine) showed broad-spectrum antimicrobial activity with Gram-positive bacteria and yeasts being more sensitive than Gram-negative bacteria. This study examines the growth and survival profIles of Klebsiella pneumoniae in the presence of pyrithione . Studies of growth and survival of Bacillus licheniformis and Candida albicans are included for comparati...

BACKGROUND 2,3-Butanediol (2,3-BD) can be used as a liquid fuel additive to replace petroleum oil, and as an important platform chemical in the pharmaceutical and plastic industries. Microbial production of 2,3-BD by Bacillus licheniformis presents potential advantages due to its GRAS status, but previous attempts to use this microorganism as a chassis strain resulted in the production of a mix...

In this study, we constructed a protein-protein interaction (PPI) network of B. licheniformis strain WX-02 with interolog method and domain-based method, which contained 15,864 edges and 2,448 nodes. Although computationally predicted networks have relatively low coverage and high false-positive rate, our prediction was confirmed from three perspectives: local structural features, functional si...

The three-dimensional immages of free and intrasporangial spores produced by scanning electron microscopy show surface structures not visible by phase-contrast microscopy. Although fine surface detail is not elucidated by scanning electron microscopy, this technique does afford a definitive picture of the general shape of spores. Spores of Bacillus popilliae, B. lentimorbus, B. thuringiensis, B...

A thermophilic strain AMF-07, hydrolyzing carboxymethylcellulose (CMC) was isolated from Kerman hot spring and was identified as Bacillus licheniformis based on 16S rRNA sequence homology. The carboxymethylcellulase (CMCase) enzyme produced by the B. licheniformis was purified by (NH4)2SO4 precipitation, ion exchange and gel filtration chromatography. The purified enzyme gave a single band on S...

BACKGROUND Polysaccharides and poly-γ-glutamic acid (γ-PGA) are biomacromolecules that have been reported as bioflocculants, and they exhibit high flocculating activity in many industrial applications. Bacillus licheniformis CGMCC 2876 can produce polysaccharide and γ-PGA bioflocculants under different culture conditions. Several key genes are involved in the metabolic pathway of polysaccharide...

This study was to isolate, screen, and identify microorganisms from fermented food Red Oncom and Tempeh Gembus that can produce fibrinolytic proteases. Forthy-three isolates showed proteolytic activities on skim milk agar, while thirthy-eight of them showed fibrinolytic activities both on a fibrin plate and a fibrinogen zymography. The isolates that showed activity in fibrin plate and fibrinoge...
