Cytotoxicity Assay for Detection of Cereulide Produced by Emetic Bacillus cereus Authors:  Elrike Frenzel and Monika Ehling-Schulz, date: 01/20/2013, view: 6371, Q&A: 0
The emetic subgroup of Bacillus cereus strains produces cereulide, a dodecadepsipeptide (1.2 kDa), which is the causative agent of food poisonings. Cereulide is synthesized by a nonribosomal peptide synthetase (NRPS), the Ces-NRPS (Ehling-Schulz et al., 2006). Cereulide is a cyclic and lipophilic potassium ionophor structurally ...

Rhodobacter capsulatus Gene Transfer Agent (RcGTA) Activity Bioassays Authors:  Alexander P. Hynes and Andrew S. Lang, date: 01/20/2013, view: 5477, Q&A: 0
RcGTA, a small phage-like particle produced by Rhodobacter capsulatus, was initially identified in culture filtrates as a DNase-resistant form of DNA transfer between R. capsulatus cells. This gene transfer assay has been used to identify RcGTA-producing strains and to help determine the roles of genes thought to be responsible ...
