Abstract
A new method to utilize spent mushroom substrates (SMS) for ethanol production was investigated. Analysis of the chemical properties of SMS revealed that they were decomposed by the mushrooms during cultivation. In particular, the free sugar content in SMS was reduced to half of that in mushrooms. Of the tested SMS, the Pleurotus eryngii SMS was determined to be suitable for saccharification. Upon pretreatment with a 1% alkaline solution, Pleurotus eryngii SMS achieved 80.7% of its maximum saccharification ratio. The optimum pretreatment conditions for enzyme saccharification were 1% NaOH solution at $120^{\circ}$ for 60 min. Further studies are required to determine ethanol production using Pleurotus eryngii SMS.
