in the present paper, the biodesulfurization of simulated light fuel oil (i.e., dibenzothiophene (dbt) in dodecane) and untreated kerosene with a high total sulfur content has been studied by a native isolated bacterium named bacillus cereus hn. the influences of various parameters such as the reaction temperature (t), biocatalyst cell density, oil phase fraction (ofp), and initial dbt concentr...

The main food source of free-living nematodes in the soil environment is bacteria, which can affect nematode development, fecundity and survival. In order to occupy a reliable source of bacterial food, some nematodes have formed specific relationships with an array of invertebrate hosts (where bacteria proliferate once the hosts dies), thus forming a tritrophic system of nematode, bacteria and ...

The species Bacillus cereus, known for its ability to cause food borne disease, consists of a large variety of strains. An important property for discrimination of strains is their growth temperature range. Fifty-two strains of Bacillus cereus isolated from different sources of food (milk, dairy product, spices and rice salad) for two years were determined to be either mesophilic or psychrotrop...

Flavobacterium johnsoniae CI04 was coisolated with Bacillus cereus from a root of a field-grown soybean plant in Arlington, WI, and selected as a model for studying commensalism between members of the Cytophaga-Flavobacterium-Bacteroides group and B. cereus Here we report the draft genome sequence of F. johnsoniae CI04 obtained by Illumina sequencing.

An association between swarming and hemolysin BL secretion was observed in a collection of 42 Bacillus cereus isolates (P=0.029). The highest levels of toxin were detected in swarmers along with swarm cell differentiation (P=0.021), suggesting that swarming B. cereus strains may have a higher virulence potential than nonswarming strains.

Bacillus cereus is increasingly being acknowledged as a serious bacterial pathogen in immunosuppressed hosts. We report a case of fatal B. cereus sepsis in a patient with newly diagnosed acute leukemia following resolving neutropenic enterocolitis. Gastrointestinal complaints are common during induction chemotherapy, yet some antimicrobial coverage suitable for generalized neutropenia is not op...

An exopolysaccharide, produced during the late stage of stationary growth phase, was discovered and purified from the culture medium of Bacillus cereus, Bacillus anthracis, and Bacillus thuringiensis when strains were grown in a defined nutrient medium that induces biofilm. Two-dimensional NMR structural characterization of the polysaccharide, named pzX, revealed that it is composed of an unusu...

AIMS In order to improve the diagnosis of Bacillus anthracis in environmental samples, we established a DNA microarray based on the ArrayTube technology of Clondiag. METHODS AND RESULTS Total DNA of a bacterial colony is randomly biotinylated and hybridized to the array. The probes on the array target the virulence genes, the genomic marker gene rpoB, as well as the selective 16S rDNA sequenc...

The objectives of this study were to compare generation and lag times of virulent Bacillus anthracis strains with those of other Bacillus strains, to identify possible surrogates for growth studies, and to determine if the B. cereus module of the U.S. Department of Agriculture Pathogen Modeling Program (PMP) had predictive value for B. anthracis. Growth characteristics of B. anthracis, B. cereu...
