摘要：

An airlift fermentor system allowing precise regulation of pH and aeration combined with a chemically defined medium was used to study growth and sporulation of Bacillus cereus ATCC 14579. Sporulation was complete and synchronous. Expression of sigA, sigB, sigF, and sigG was monitored with real-time reverse transcription-PCR, and the pattern qualitatively resembled that of Bacillus subtilis. This method allows reproducible production of stable spores, while the synchronous growth and defined conditions are excellently suitable for further gene expression studies of cellular differentiation of B. cereus.
