Abstract Amorphophallus konjac is rich in glucomannan, which can be hydrolyzed
into glucose and mannose, thereby acting as an economic raw material for the acquisition of glucose and mannose. The total sugar yield was 91.2% when konjac powder
was treated with 0.75% hydrochloric acid at 121°C for 1 h. Thus, dilute acid hydrolysates of konjac powder were used as a carbon source for obtaining value-added
products. Here we showed that the microbial production of ethanol and mannonic
acid was obtained by employing Candida shehatae (C. shehatae) and Gluconobacter
oxydans (G. oxydans). Through a step-by-step bioprocess, glucose is the first selectively converted… More >
