Effects of target pH-value on organic acids and methane production in two-stage anaerobic digestion of vegetable waste.

abstract：:Syngas from biomass or steel mills can be fermented into a dilute stream of ethanol and acetic acid, which requires energy intensive distillation for product recovery. This can be circumvented by selective secondary fermentation of the syngas fermentation effluent to caproic acid as easier recoverable platform chemica...
