In the process of fermented Simultaneous saccharification and fementation (SSF) is the ethanol fermentation from raw materials of lignosulfonate เซลลูโลสโดย degradation coupled with fermentation. From the report of the isolation of yeast strains, Saccharomyces cerevisiae50 species, when tested, it was found that the growth S.Cerevisiae LBM-1 has the ability to grow best at 42 C, and other species to be chosen to test the production of ethanol. Is Kluyveromyces marxianus UFV-3.The two strains of yeast growth ability test temperature and 30 42 45 degrees Celsius, it was found that the Kluyveromyces marxianus. UFV-3 can grow better than the other species.SSF compared between with and without the presaccharitication fermentation temperature 42 C found in fermentation. SSF with step presaccharitication for 72 hours at 50 C and ferment for 8 hours.1.79 g / L, which was a SSF fermentation process and no presaccharitication fermentation, Separate hydrolysis And fermentation (SHF) which are presaccharitication can produce less than SSF fermentation process, with presaccharitication As well.
