Bacillus cereus was isolated from soil and employed for this purpose in this study due to its high urease activity. The strain exhibited strong tolerance for alkaline media and high salt levels, which grew at a pH of 13 and 4% salt concentration. The repair of concrete cracks with this ...
To characterize the isolated bacteria, a comprehensive battery of biochemical assays was employed, including Gram staining and tests for methyl red, catalase, citrate utilization, indole production, Voges-Proskauer test, starch hydrolysis, urease activity, oxidase test, nitrate reduction, motility, hydroge...

The test of hemolysis can be performed to differentiateB. anthracisfromB. cereusthat is β-hemolytic. 2. Antigen-based Methods Antigen detection by immunoassay is an alternate approach to the diagnosis ofB. anthracis. Common antigens used for these methods are glycoprotein BclA of the exosporium,...
no significant difference was observed in urease activity between the Y treatments and YC treatments; however, it was significantly higher than that in the CK and inoculated pathogen groups. The cellulase activity of sugarcane rhizosphere soil with YC treatments was significantly higher than that of ...
our results confirmed that the partial sequence of thegyrBhousekeeping gene could be a useful and easy tool to separate these species. ThegyrBgene sequences have been used in phylogenetic studies of theBacillus anthracis–cereus–thuringiensisgroup24, as a suitable phylogenetic marker for species-level...

cereus DZ-h with amylase activities as 20.5 and 24.2 U/mL respectively. The gene encoding for amylase production was cloned in E. coli demonstrating successful expression in the host. Feng, Wang, Zhou, Liu, and Wan (2011) evaluated the lipase producing ability of gut microbiota from fourth ...
cereus (food poisoning) and B. anthracis (anthrax) [13]. Other species may also be found in various human infections, including pneumonia, endocarditis, and ocular, cutaneous, bone or central nervous system infections and bacteraemia [14]. The following is a summary classification and a set ...
