cereus and closely related species are currently based on biochemical tests. The main problem is to discriminate between B. cereus and B. thuringiensis . Sequencing part of the 16S rRNA showed that several B. cereus isolates present in food and involved in food poisoning, confirmed according to ...
Presence of B.cereus in samples entering the whey transfer line was low (<10%) but the frequency increased towards the end of the line, suggesting that equipment such as pipelines carried biofilms containing B.cereus. Biochemical tests, phage typing and whole cell fatty acid analysis were used...

cereus through microbiological and biochemical tests7. Since these genetic methods are not able to easily distinguish different members of B. thuringiensis, B. anthracis and B. cereus, it becomes necessary to look for some more easily recognizable markers. With the advent and development of next ...
Biochemical characterization and enzyme activity profiling 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 activ...
Therefore, the selected Bacillus isolate was further subjected to identification to the species level using standard biochemical tests as described in Bergey’s Manual of Bacteriology as well as the 16S rRNA. Based on the results, it was identified as Bacillus cereus depending on the biochemical cha...

Classic methods of microorganism identification, such as biochemical tests and DNA sequencing, are time-consuming and labor-intensive. The more recently developed approach that uses MALDI TOF mass-spectrometry is simple and rapid. It is based on the comparison of protein spectrum of the studied speci...
Characterization of Bacillus cereus isolates from fresh vegetables and refrigerated minimally processed foods by biochemical and physiological tests firmus. About 81·3% (26 strains) of 32 B. cereus tested isolates hydrolysed starch and 71·9% (23 strains) produced diarrheal enterotoxin in TSB ... ...
