PDMS/ceramic composite membrane for pervaporation separation of acetone–butanol–ethanol (ABE) aqueous solutions and its application in intensification of ABE fermentation process
Pervaporation (PV) has attracted increasing attention because of its potential application in bio-butanol recovery from fermentation process. In this work, PDMS/ceramic composite membrane was employed for PV separation of acetone–butanol–ethanol (ABE) aqueous solutions. The influence of coupling effect on the molecular transport during the PV process was systematically investigated. The separat...
متن کاملApplied in situ product recovery in ABE fermentation
The production of biobutanol is hindered by the product's toxicity to the bacteria, which limits the productivity of the process. In situ product recovery of butanol can improve the productivity by removing the source of inhibition. This paper reviews in situ product recovery techniques applied to the acetone butanol ethanol fermentation in a stirred tank reactor. Methods of in situ recovery in...
متن کاملThe cause of "acid-crash" and "acidogenic fermentations" during the batch acetone-butanol-ethanol (ABE-) fermentation process.
Experiments were performed to determine the cause of "acid crash", a phenomenon which occasionally occurs in pH-uncontrolled batch fermentations resulting in premature cessation of ABE (acetone butanol) production. The results indicate that "acid crash" occurs when the concentration of undissociated acids in the broth exceeds 57 - 60 mmol/l. Prevention can be achieved by introducing some limite...
متن کاملIntroducing a single secondary alcohol dehydrogenase into butanol-tolerant Clostridium acetobutylicum Rh8 switches ABE fermentation to high level IBE fermentation
UNLABELLED BACKGROUND Previously we have developed a butanol tolerant mutant of Clostridium acetobutylicum Rh8, from the wild type strain DSM 1731. Strain Rh8 can tolerate up to 19 g/L butanol, with solvent titer improved accordingly, thus exhibiting industrial application potential. To test if strain Rh8 can be used for production of high level mixed alcohols, a single secondary alcohol deh...
متن کاملProcess strategies for cephalosporin C fermentation
Cephalosporin C (CPC), a β-lactam antibiotic, is starting molecule for industrial production of semi synthetic cephalosporins. CPC fermentation has been carried out in Air Lift Reactor (indigenously made up of borosilicate glass) in different fermentation modes i.e., batch and fed batch modes using a mold Acremonium chrysogenum (synn. Cephalosporium acremonium). A definite correlation exists be...
