| Abstract |
Mushroom cultivation waste material (MCWM) was utilized as a lignocellulosic source for cellulolytic enzyme production by Aspergillus tubingensis HS1-5 and bioethanol production. The appreciable level of cellulolytic enzymes was produced under a moisture content of 65%, pH 5.0 and 30 ºC. Pretreatment of MCWM with 1% H2SO4 at 121 ºC for 90 min was effective, resulting in high fermentable sugar yields. Enzymatic hydrolysis was performed using the substrate-to-enzyme volume ratios of 1:0.5, 1:1 and 1:2 and glucose concentration was maximal with the substrate-to-enzyme volume ratio of 1:0.5 at 24 h. The scanning electron microscope (SEM) images indicated that acid pretreatment and enzymatic hydrolysis exerted the disintegration of MCWM structure and the release of fermentable sugars. The ethanol yield produced from MCWM by S. cerevisiae TISTR 5339 was 0.42 g ethanol/g sugar, corresponding to 82.30% of the theoretical yield. These findings suggest that MCWM is an appropriate lignocellulosic source for cellulolytic enzyme production and can be effectively used for bioethanol production. |
