Production, purification, and application of microbial enzymes
Downstream processing/enzyme purification. The goal of the fermentation process is to produce a final formulated enzyme product, and it also includes many postfermentation unit operations. Still, the maximum production rate could be the most important factor. However, the lowest unit production cost could also be an important Diethyl carbonate (DEC) was evaluated as a green, renewable alternative to methyl isobutyl ketone and dibutyl carbitol for the recovery of gold from copper-rich sources, such as anode slimes, by solvent extraction from chloride solutions.
