In this study it was aimed to improve impregnability of spruce (Picea orientalis L.) wood with bacteria (Bacillus licheniformis A1) pretreatment, using copper/chromium/arsenic Type C (CCA-C) and copper azole Type A (CBA-A). The effects of Bacillus licheniformis A1 on weight loss, copper uptake, and compression strength of samples were determined. Weight loss was slightly changed by bacterial de...

Bacillus accelerates lignocellulose degradation, promotes the stabilization and resource utilization of compost by secreting enzymes, plays an important role in formation quality control. This study evaluated enzyme activity, lignocellulosic bacterial succession composting inoculated with different microbial agents. They were identified as B. licheniformis, subtilis, thermoamylovorans, thermoru...

Membrane-bound penicillinases in Gram-positive bacteria are glyceride-cysteine lipoproteins (Nielsen, J. B. K., and Lampen, J. 0. (1982) J. Biol. Chern. 257, 4490-4495) that can be, but are not necessarily, intermediates in formation of exocellular enzymes. We have now deleted from the signal region of the Bacillus licheniformis 749/C B-lactamase gene (penP) 15 base pairs that code for Ala-Leu-...

BACKGROUND Lantibiotics are small microbial peptide antibiotics that are characterized by the presence of the thioether amino acids lanthionine and methyllanthionine. Lantibiotics possess structural genes which encode inactive prepeptides. During maturation, the prepeptide undergoes posttranslational modifications including the introduction of rare amino acids as lanthionine and methyllanthione...

Crude glycerol is generated as a by-product during transesterification process and during hydrolysis of fat in the soap-manufacturing process, and poses a problem for waste management. In the present approach, an efficient process was designed for simultaneous production of 0.2 g/L extracellular ε-polylysine and 64.6% (w/w) intracellular polyhydroxyalkanoate (PHA) in the same fermentation broth...

Bacillus licheniformis JF-2 anaerobically produced a biosurfactant when grown in a glucose-mineral salts medium containing yeast extract and NaNO(3). Surface tension of the medium was reduced from 70 to 74 mN/m to as low as 28 mN/m due to the production of an anionic biosurfactant.

A bacterial culture was isolated from oil-contaminated soil based on its ability to metabolize the quinoline as the sole source of nitrogen. In this research Bacillus licheniformis strain was identified based on the result of 16S rRNA analysis. Optimized conditions were obtained with full factorial experimental design method using design expert software at temperature: 32C, agitation speed: 200...

The effects of single and combined use of two different probiotic bacterial species, Bacillus licheniformis and Lactobacillus rhamnosus on growth performance of Pacific white shrimp Litopenaeus vannamei was evaluated. Shrimp were treated with probiotics in entire crop duration with different test diets. Twelve culture ponds were divided into four groups of each three, Control (CP) without probi...
