TL;DR: Both pH and solution COD were found to correlate with regeneration completion as measured by organic residue on GAC surfaces in four regeneration cycles with acetone, and both resulted in destruction efficiency of adsorbed acetone on the GAC surface was more than 99%.

TL;DR: In this paper, a novel glucose/acetate co-substrate system incorporating with C. cerevisiae co-culturing and glucose limitation was proposed and applied in ABE fermentations by C. acetobutylicum.

01 Jul 1983TL;DR: Overall results in terms of conversion yields, solvent productivity and residual glucose concentration are similar or superior to previously reported results with continuous fermentation.
Abstract: Acetone and butanol are produced by continuous culture of Clostridumacetobutylicum on an optimized synthetic medium containing 45 g/l glucose. Overall results in terms of conversion yields, solvent productivity and residual glucose concentration are similar or superior to previously reported results with continuous fermentation.

14 Feb 1980TL;DR: In this paper, poly-3-hydroxybutyric acid is separated from bacterial cells by drying a finely divided stream or spray of an aqueous suspension of the cells with a gas heated to above 100°C and then extracting the PHB, preferably after a lipid extraction step with a solvent such as methanol or acetone, with a PHB-solvator such as a partially halogenated hydrocarbon such as 1,2-dichloroethane, chloroform or dichloromethane.
Abstract: Poly-3-hydroxybutyric acid is separated from bacterial cells by drying a finely divided stream or spray of an aqueous suspension of the cells with a gas heated to above 100°C and then extracting the PHB, preferably after a lipid extraction step with a solvent such as methanol or acetone, with a PHB- solvent such as a partially halogenated hydrocarbon such as 1,2-dichloroethane, chloroform or dichloromethane. 1,2-Dichloroethane may also be used to extract PHB directly from an aqueous cell suspension without an intermediate drying step. In this case, for some bacteria, the suspension is preferably subjected to a cell disruption step, eg milling, prior to contact with the 1,2-dichloroethane.
