Strains from four different DNA relatedness groups of Bacillus circulans showed apparent alginate lyase activity; the activity of three strains examined had mannuronidase specificity. A representative strain of group 4 also produced apparent inducible unsulfated chrondroitin lyase activity.

The occurrence, structure, and glycosylation of lipoteichoic acids were studied in 15 Bacillus strains, including Bacillus cereus (4 strains), Bacillus subtilis (5 strains), Bacillus licheniformis (1 strain), Bacillus polymyxa (2 strains), and Bacillus circulans (3 strains). Whereas in the cells of B. polymyxa and B. circulans neither lipoteichoic acid nor related amphipathic polymer could be d...

Here, we report the complete genome sequence for the Bacillus circulans Jordan strain 32352. This species is a soil dwelling bacterium that expresses glycosyl hydrolase enzymes degrading pneumococcal capsular polysaccharides.

Enzymatic synthesis of galacto-oligosaccharides is usually performed at high initial substrate concentrations since higher yields are obtained. We report here on the stability of β-galactosidase from Bacillus circulans at 25, 40, and 60°C in buffer, and in systems with initially 5.0 and 30% (w/w) lactose. In buffer, the half-life time was 220 h and 13 h at 25 and 40°C, respectively, whereas the...

The most intensive study of the aerobic sporeforming bacteria (Smith et al., 1952) has revealed the lack of a clear-cut distinction between thermophilic and mesophilic species of the genus Bacius. It was found, however, that of the many cultures studied, only those belonging to the species BaciUlus stearotenwophilus would grow at 65 C. Some cultures of Bacillus coagulans, Bacius subtilie, Bacil...

A bacterium capable of degrading herbicide, pendimethalin, was isolated from the contaminated soil by enrichment culture technique and identified as Bacillus circulans. The organism grew on pendimethalin (1 g/L) as the sole source of carbon and accumulated 6-aminopendimethalin and 3,4-dimethyl 2,6-dinitroaniline as metabolites in the culture medium. The cell-free extract of B. circulans grown o...

Two genes coding for xylanase synthesis in Bacillus circulans were cloned and expressed in Escherichia coli. After digestion of genomic DNA from Bacillus circulans with EcoRI and PstI, the fragments were ligated into the corresponding sites of pUC19 and transformed into Escherichia coli. Restriction enzyme mapping of the two inserts coding for xylanase activity indicated distinctly different nu...

The thermophilic islolates of Mangho-pir spring water were of bacillary forms. All were gram positive, sporing rods, varying in sugar reactions; one being non saccharolytic, two monosaccharolytic, one disaccharolytic and nine fermented four or more sugars. All belonged to genus Bacillus of family Bacillaceae. All were found to be thermophilic varieties of ter-ristrial mesophilic species of genu...

Pure cultures of a gram-negative, rod-shaped bacterium, which produced endospores after 3 to 5 days on solid medium, were isolated exclusively from tissue cultures of the date palm Phoenix dactylifera L. Electron microscopic examination of thin sections of the bacteria revealed the bilayer membrane typical of gramnegative bacteria and confirmed the nature of the spores as true endospores. Bioch...
