Abstract:
... Oil palm empty fruit bunch (OPEFB) is a potential raw material for production of lignocellulosic bioethanol. The OPEFB was pretreated with 8% sodium hydroxide (NaOH) solution at 100°C for 10 to 90 min. Enzymatic digestion was carried out using cellulase and β-glucosidase at 45°C for 24 h. It was then inoculated with Mucor indicus spores suspension and fermented under anaerobic conditions at 37°C f ...

Abstract:
... Sweet sorghum is one of the most promising energy crops for ethanol production. Fungal solid state fermentation (FSSF) of dry sweet sorghum stalk particles (DSSSPs) for ethanol production was conducted using fungus Mucor indicus and followed by simultaneous saccharification and fermentation of the residual solid without any pretreatment and addition of fresh microorganism cells. The effects of imp ...

BGLs 1 and 2 are monomeric glycoproteins whose apparent molecular masses (Ms) are around 78 kDa, which decreased by approximately 10 kDa upon enzymatic deglycosylation. Both BGLs showed similar enzyme char ...

Abstract:
... This study evaluated the changes in contents and composition of soybean isoflavone as well as the β-glucosidase production during sufu preparation by Mucor flavus (M. flavus) at low temperature. The results showed that sufu processing not only led to the losses of isoflavones but also caused the redistribution of isoflavone isomers. The levels of aglycones increased during sufu fermentation, while ...
