In the previous research about ethanol production, we confirmed that SFW(saccharified foodwastes) medium(0.56g-ethanol/g-glucose) is more efficient than YM medium(0.538g-ethanol/g-glucose). Ethanol production using SFW needs large enzyme cost due to the enzymatic hydrolysis of foodwastes, although the enzymes was obtained from our economical enzyme production methods, using the intact whole culture broth of Trichoderma harzianum FJ1. Therefore, in this research we used synchronous saccharification and fermentation method to produce ethanol using foodwastes. Ethanol production yield was 0.45g-ethanol/g-reducing sugar in synchronous saccharification and fermentation by a fed-batch mode.

Acetobacter pasteurianus is usually used for vinegar fermentations, however, the growth of A. pasteurianus was commonly inhibited by high ethanol concentration. In this research, the ethanol resistance of A. pasteurianus CGMCC 3089 was improved by a continuous ethanol stress adaptation culture. The characterization of A. pasteurianus CGMCC 3089 during the evolutionary process of adaptation to ethanol was performed with respect to the improved resistance to ethanol. It was found that the ethanol resistance of A. pasteurianus was related to the activities of alcohol dehydrogenase (ADH) and aldehyde dehydrogenases (ALDH). Furthermore, the improved resistance against ethanol was an inheritable phenotype, instead of a transient physiologic adaptation. The results of Random Amplified Polymorphic DNA (RAPD) suggested that there was some diversity between the genomes of the original strain and the evolutionary strain.
