TWR sugar was produced from TWR with Amylomyces rouxii TISTR 3182. Response surface methodology (RSM) was applied for investigating the experimental design for production the alcohol. There were 20 experiments involving the three investigated variables of Saccharomyces cerevisiae TISTR 5339 to amount of TWR sugar ratio, concentration of TWR sugar (% Brix) and retention time of fermentation that were studied on alcohol to optimize the condition for production the alcohol. Design of experiment was performed by application of 5-level-3-factors central composite design in order to study the optimum condition for production the alcohol. The investigated results showed that the optimum condition was 4.0 ml of Saccharomyces cerevisiae TISTR 5339 amount to 100 ml of TWR sugar amount, 20%Brix (concentration of TWR sugar) and 7 days of fermentation time.

The cells were motile, rod-shaped and Gram-stain-negative. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that strain hydD52 was a member of the genus Sulfitobacter and most closely related to Sulfitobacter dubius DSM 16472 (98.0 %), Sulfitobacter indolifex HEL-45 (97.8 %) and Sulfitobacter delicatus DSM 28223 (97.6 %). The major fatty acids (>5 %) of hydD52 were C18 : 1ω7c/C18 : 1ω6c, C16 : 0, C18 : 1ω7c 11-methyl and C19 : 0ω8c. The respiratory quinone of strain hydD52 was ubiquinone-10. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine and an unidentified amino lipid. The G+C content of this strain was 64.0 mol%. The DNA-DNA relatedness values of hydD52 with the type strains of S. dubius, S. indolifex and S. delicatus were 18.8, 13.1 and 15.7 %, respe...
