Production of recombinant versatile peroxidase in Aspergillus hosts was optimized through the modification of temperature during bioreactor cultivations. To further this purpose, the cDNA encoding a versatile peroxidase of Pleurotus eryngii was expressed under control of the alcohol dehydrogenase (alcA) promoter of Aspergillus nidulans. A dependence of(More)
Solvent screening for in situ liquid extraction of products from acetone-butanol-ethanol (ABE) fermentation was carried out, taking into account biological parameters (biocompatibility, bioavailability, and product yield) and extraction performance (partition coefficient and selectivity) determined in real fermentation broth. On the basis of different(More)
Acetone/butanol/ethanol (ABE) fermentation by Clostridium acetobutylicum was investigated in extractive fed-batch experiments. In conventional fermentations, metabolic activity ceases when a critical threshold products concentration is reached (~21.6 g solvents l−1). Solvents production was increased up to 36.6 and 37.2 g l−1, respectively, using(More)
