The pH of the water associated with toxic blooms of cyanobacteria is typically in the alkaline range; however, previously only microcystin-degrading bacteria growing in neutral pH conditions have been isolated. Therefore, we sought to isolate and characterize an alkali-tolerant microcystin-degrading bacterium from a water bloom using microcystin-LR. Analysis of the 16S rRNA gene sequence reveal...

This study was conducted to determine a disease outbreak in 14 day old post-larvae of abalone (Haliotis diversicolor supertexta) which caused mass mortality in July 2010 in Shanwei, China. Twenty-nine bacterial strains were isolated from a sample pool of 10 diseased post-larval abalones on 2216E marine agar plates during a natural outbreak of the disease. Among them, a dominant isolate (referre...

the tremendous mounting interest in lipase production is pertinent to the biotechnological applications that these enzymes offer. lipase, belonging to the hydrolyze enzymes, is involved in copious biological functions including: hydrolysis insoluble triacylglycerol to mono and diacylglycerols and glycerol. submerge fermentation technique was applied for the efficient production of this. briefly...

An aerobic and heterotrophic isolate, designated IFAM EL-30T, was obtained from hypersaline Ekho Lake (Vestfold Hills, East Antarctica). The isolate consisted of Gram-positive cocci or short rods which occasionally exhibited branching. The organism was moderately halotolerant, required thiamin.HCI and was stimulated by biotin and nicotinic acid. It grew well with glucose, acetate, pyruvate, suc...

An aerobic gram-negative bacterium was isolated from the blood and sputum of an 84-year-old, chair-bound nursing home resident with acute bacteremic pneumonia. Although the phenotypic characteristics suggested that the bacterium could be Burkholderia pseudomallei, the Vitek 1 system (GNI+), which can successfully identify 99% of B. pseudomallei strains, showed that the bacterium was "unidentifi...

Chicken feathers are major poultry waste that is difficult to process in its native form due highly resistant keratin protein large amounts. In this study, a novel feather-degrading bacterium, Bacillus amyloliquefaciens KB1, was screened from chicken farm bed (CFB) using morphological and biochemical tests followed by 16s rDNA analysis. Among observed isolates, bacterial isolate (KB1) showed th...

The antimicrobial activities of certain spices and herbs are well-documented. Herbs often exposed to bacterial contamination, spore-forming bacteria in particular. spores introduced during the production process result a contamination that causes food alteration storage. aim this study was isolate from commercially available herbs, such as ginger, cinnamon, black pepper, curcumin, saffron, clov...

Recently developed techniques for isolating forespores from bacilli at all stages of spore morphogenesis have been exploited to investigate the contribution of each of the two compartments of the sporulating cell to the overall pattern of protein synthesis and degradation during sporulation in Bacillus megaterium. These studies have shown: (1) that protein synthesis continues in both compartmen...
