Bacillus spp. are Gram-positive spore-forming bacteria used commercially as probiotics in the larviculture of fish. Bacillus spp. can act positively on cultured organisms by enhancing their survival and growth, stimulating their digestive and immune systems, and improving water quality. In this present study, grass carp larvae were fed on Artemia urmiana, Artemia fransiscana and Artemia parthen...

Bioremediation of chromated copper arsenate-treated waste wood with one or more metal-tolerant bacteria is a potential method of naturally releasing metals from treated wood fibre. Sampling eight environments with elevated levels of copper, chromium, and arsenic resulted in the isolation of 28 bacteria with the capability of releasing one or more of the components from chromated copper arsenate...

Wastewater sludge is a complex raw material that can support growth and protease production by Bacillus licheniformis. In this study, sludge was treated by different thermo-alkaline pre-treatment methods and subjected to Bacillus licheniformis fermentation in bench scale fermentors under controlled conditions. Thermo-alkaline treatment was found to be an effective pre-treatment process in order...

Halmann, M. (The Israel Institute for Biological Research, Ness Ziona) and A. Keynan. Stages in germination of spores of Bacillus licheniformis. J. Bacteriol. 84:1187-1193. 1962.-This work defines conditions under which the first biochemical step in germination of spores (the so-called trigger reaction) could be studied separately from subsequent steps in germination. Although the initiation of...

The methods suggested for the identification of species of the genus Bacillus in the invaluable monographs of Smith et al. (1946, 1952) have been applied to a collection of named cultures, and also have been utilized for the classification of approximately 400 strains of these organisms isolated from samples of blood, spinal fluid, surgical tissue, and other human and animal sources, as well as...

The structural gene for alkaline phosphatase (orthophosphoric monoester phosphohydrolase; EC 3.1.3.1) of Bacillus licheniformis MC14 was cloned into the Pst1 site of pMK2004 from chromosomal DNA. The gene was cloned on an 8.5-kilobase DNA fragment. A restriction map was developed, and the gene was subcloned on a 4.2-kilobase DNA fragment. The minimum coding region of the gene was localized to a...

One hundred nineteen species of Bacillus were isolated from five heavily contaminated liquid antacids and their constituent chemicals. The 66 different reaction profiles obtained were expressed in probability figures and stored in a computer. A total of 13 Bacillus species were identified, with B. coagulans, B. licheniformis, B. subtilis, and B. polymyxa present at particularly high frequencies...

The Bacillus licheniformis strain isolated from the intestine of Labeo rohita by an enrichment technique showed capability of utilizing dimethoate as the sole source of carbon. The bacterium rapidly utilized dimethoate beyond 0.6 mg/mL and showed prolific growth in a mineral salts medium containing 0.45 mg/mL dimethoate. The isolated B licheniformis exhibited high level of tolerance of dimethoa...

A feeding trial was conducted to investigate effects of Bacillus licheniformis on growth performance and meat quality of broilers. Nine hundred one-d-old broiler chicks were randomly assigned to 3 experimental groups with three replicate pens of 100 broiler chicks. Three treatments were i) control, ii) basal diets supplemented with 1 ml of B. licheniformis for each in feed water per day iii) ba...

halophilic bacteria grow over a wide range of salt concentrations. in this study we aimed to isolate and screen out the halophilic bacteria and to determine their activity for production of the bioactive compounds. a total of 50 water, sediments and soil samples were collected from maharlu salt lake in southern region of fars-iran and subjected for isolation of the bioactive compound producing ...
