Parameters Affecting Solvent Production by Clostridium pasteurianum.
The effect of pH, growth rate, phosphate and iron limitation, carbon monoxide, and carbon source on product formation by Clostridium pasteurianum was determined. Under phosphate limitation, glucoseExpand

Metabolic engineering of Clostridium acetobutylicum: recent advances to improve butanol production.
The biosynthesis of the solvents 1-butanol and acetone is restricted to species of the genus Clostridium, a diverse group of Gram-positive, endospore forming anaerobes comprising toxin-producingExpand

Purification and properties of two chitinolytic enzymes of Serratia plymuthica HRO-C48
Abstract. The chitinolytic rhizobacterium Serratia plymuthica HRO-C48 was previously selected as a biocontrol agent of phytopathogenic fungi. One endochitinase (E.C., CHIT60, and oneExpand

Effect of pH and butyrate concentration on the production of acetone and butanol by Clostridium acetobutylicum grown in continuous culture
SummaryWhen Clostridium acetobutylicum was grown in continuous culture under glucose limitation at neutral pH and varying dilution rates the only fermentation products formed were acetate, butyrate,Expand

Level of enzymes involved in acetate, butyrate, acetone and butanol formation by Clostridium acetobutylicum
SummaryClostridium acetobutylicum cells were collected from chemostats which were run at pH 4.3 or 6.0 and which produced either acetone-butanol or acetate-butyrate; they were used to determine theExpand

Continuous production of acetone and butanol by Clostridium acetobutylicum in a two-stage phosphate limited chemostat
SummaryWhen Clostridium acetobutylicum was grown in continuous culture under phosphate limitation (0.74 mM) at a pH of 4.3, glucose was fermented to butanol, acetone and ethanol as the majorExpand

Modifying the product pattern of Clostridium acetobutylicum
Clostridial acetone–butanol–ethanol (ABE) fermentation is a natural source for microbial n-butanol production and regained much interest in academia and industry in the past years. Due to theExpand

The redox-sensing protein Rex, a transcriptional regulator of solventogenesis in Clostridium acetobutylicum
Solventogenic clostridia are characterised by their biphasic fermentative metabolism, and the main final product n-butanol is of particular industrial interest because it can be used as a superiorExpand

Genome-Wide Gene Expression Analysis of the Switch between Acidogenesis and Solventogenesis in Continuous Cultures of Clostridium acetobutylicum
Clostridium acetobutylicum is able to switch from acidogenic growth to solventogenic growth. We used phosphate-limited continuous cultures that established acidogenic growth at pH 5.8 andExpand

A proteomic and transcriptional view of acidogenic and solventogenic steady-state cells of Clostridium acetobutylicum in a chemostat culture
The complex changes in the life cycle of Clostridium acetobutylicum, a promising biofuel producer, are not well understood. During exponential growth, sugars are fermented to acetate and butyrate,Expand
