(Submitter supplied) Immobilization of Clostridium acetobutylicum B3 onto fibrous matrix by surface-adsorption was developed and applied to biobutanol production. The immobilized C. acetobutylicum B3 cells formed biofilm and showed dramatically improved butanol tolerance and production rate. DNA array-based transcriptional analysis of C.acetobutylicum B3 biofilm cells was conducted to elucidate the gene expression profile of the biofilm cells. more...

(Submitter supplied) Clostridium acetobutylicum is a Gram positive, endospore forming firmicute that has been known as the model organims for ABE (acetone-butanol-ethanol) fermentation. With its ability to consume a wide variety of substrates, C. acetobutylicum carries out a biphasic ABE fermentation, which consists of the acidogenic growth phase with the formation of butyric acid and acetic acid, followed by the solventogenic stationary phase with the formation of acetone, butanol and ethanol, characterised by the reassimilation of acids. more...

(Submitter supplied) Previously, we performed DNA array-based transcriptomic analysis of Clostridium acetobutylicum biofilm adsorbed onto fibrous matrix in batch fermentation. Here, to further shed light on the transcriptomic modulation of maturing Clostridium acetobutylicum biofilm, we performed the DNA array-based transcriptomic analysis in repeated-batch fermentation. Significant time course changes in expression levels were observed for the genes involved in amino acid metabolism, oligopeptide ABC transporter, nitrogen fixation, and various other processes.

(Submitter supplied) Streptococcus pneumoniae is a Gram positive bacterium that causes severe invasive infection such as pneumonia, septicemia, meningitis and otitis media especially in children, the elderly and immune-compromised patients. Pneumococcal colonization and disease is often associated with biofilm formation. Bacteria in biofilms exhibit elevated resistance both to antibiotics and to host defense systems, which often results in persistent and difficult-to-treat infections. more...
