Bacillus cereus, selective

Amplification products were obtained only for Bacillus cereus out of the microorganisms reported in Table 6, allowing their application in the selective detection of B. cereus strains directly in foods. 

Hinton Agar by following the reported method [4]. Four test pathogenic bacterial strains viz Bacillus cereus (MTCC 1272), Salmonella typhi (MTCC 733), Escherichia coli (MTCC 739), and Staphylococcus aureus (MTCC 1144) were considered for determination of Minimum Inhibitory Concentration (MIC) of selected complexes.

Lasch and cowoikers describe in Chap. 8 their group s efforts to improve taxonomic resolution without compromising the simplicity and the speed of MALDI TOF MS. Such improvements may be achieved by signature database expansion with novel and diverse strains, optimization, and standardization of sample preparation and data-acquisition protocols. Further enhancement in data analysis pipelines including more advanced spectral preprocessing, feature selection, and supervised methods of multivariate classification analysis also contribute to taxonomic resolution enhancements. Strains of Staphylococcus aureus. Enterococcus faecium, and Bacillus cereus are selected to illustrate aspects of that strategy. 

Surface-activated glass slides with immobilized lectins have been reported to selectively capture bacteria (E. coli) and bacterial spores (Bacillus cereus and Bacillus subtilis) (Afonso and Fenselau 2003).

Few microbial proteases acting on n-peptides are known. The alkaline D-peptidase (ADP) from Bacillus cereus is related to Du-carboxypeptidase and p-lactamases. These enz unes have an accessible groove in which the nucleophilic serine and other catalytic amino acids are located. This n-peptidase could be applied for the synthesis of the 92-amino acid peptidyl prolyl cis-trans isomerase from Escherichia coli by condensation of two peptide fragments, of which the 35-amino acid acyl donor was activated as the OGp ester [62]. Thus the D-amino acid-selective enzyme was used for preparing a protein composed of L-amino acids and making the product insensitive to hydrolysis by the coupling enzyme.
