Twenty-two strains of Saccharomyces cerevisiae isolated from tape-mash for the production of brem, a traditional rice wine from Bali, Indonesia, were divided into three groups (I, II, and III) based on the sequences of the rDNA spacer region and SUC2 gene. DNA analyses suggested that the seventeen strains in groups II and III were taxonomically closer to baking strains than the five strains in group I. These differences were reflected in their leavening ability in dough with and without addition of 5% sucrose, and their α-glucosidase activity, although most of the strains did not leaven dough with addition of 30% sucrose. Strain S-10 in group II showed a high rate of CO2 production from sponge dough without addition of sugar and consumed fermentable sugar... |

We examined the effects of Amylomyces rouxii, which is a mold found in some fermented foods in Indonesia, on serum cholesterol and hepatic LDL receptor mRNA in rats. Rats were fed a 0.5% cholesterol-enriched diet with (A. rouxii group) or without (control group) 30g/kg A. rouxii for 4 wk. There were no significant differences in the body weight, food intake or liver weight among the groups. However, the weight of the cecum in the A. rouxii-fed group was significantly higher than that in the control group. The cecal pH in the A. rouxii-fed group was significantly lower than that in the control group. Cecal acetic acid, propionic acid and total SCFA concentrations in the A. rouxii-fed group were significantly higher than those in the control group. The serum... |

The yeast strain AK 46 was isolated from dough containing fermented cherry fruits and identified as Saccharomyces cerevisiae. The nucleotide sequence of the rDNA spacer region from this strain coincided with those from the yeasts used for the production of whisky, wine, and bread. In a comparison with six baking strains, strain AK 46 possessed less leavening ability in dough with and without addition of 5% sucrose (based on the weight of flour) but a high ability in sweet dough containing 30% sucrose. The activities of the two enzymes α-glucosidase and invertase, which are related to dough fermentation, were lower than those in the other strains. A baking test showed that strain AK 46 was applicable for breadmaking using the straight dough and sponge dough... |

By-products from potato processing plants were liquefied and partially saccharified using three commercially available enzymes, followed by ethanol fermentation by yeast and then hydrolysis by glucoamylase. From 12% (w/w) of fresh potato peel, about 20 mg/mL ethanol was formed in the supernatant via amylase, pectinase, or an enzyme complex; this yield was slightly increased with combinations of these enzymes. Supplementation of substandard mash to potato peel (1:1) as a raw material enhanced the amount of ethanol formation, increasing it to approximately 50 mg/mL by the mixture of all three enzymes. After the addition of yeast and glucoamylase to the partially saccharified material, ethanol formation proceeded gradually and slowed in 12 h with the... |
