In the sake mashing process, we established the following four stages for optimal control of sensory evaluation. (1) To estimate the sensory evaluation value from the component concentrations of sake . (2) To create a model that can approximate the t

The sake yeast Saccharomyces cerevisiae Kyokai no. 7 (K-7) is capable of producing more than 20% (v/v) ethanol in culture. However, the activity of its alcohol dehydrogenase (ADH), which is a key enzyme in alcohol production, is less than that of the

We used a plasmid carrying a sequence for autonomous maintenance in Aspergillus (AMA1) and the E. coli uidA gene as a reporter gene to search the A. oryzae and A. niger genomes for DNA fragments having strong promoter activity. Beta-glucuronidase (GU

Sensory evaluation data obtained from experts were analyzed by numerical methods. The aim of this study is to identify a model that can objectively estimate the sensory evaluation results based on the concentrations of components in sake. To this aim

The effects of ultrasonic wave irradiation on cell growth and the formation of ethanol and other volatile components in the fermentation process were investigated. The fermentation periods were reduced to 50–64% in wine, beer, and sake made from sa

A new rapid transformation system for Aspergillus niger that uses electroporation to render intact germinating conidia permeable to DNA is described. The transformant colonies appeared earlier than transformants obtained by the protoplast-forming met

Isoamylalcohol and isoamylacetate concentrations were analyzed at various isothermal conditions in sake brewed with a saccharified rice solution. Kinetic models for formation of these components were constructed in which the relation between the isoa

The nucleotide sequence of a 1.5-kb fragment of the promoter region of the Aspergillus oryzae agdA gene encoding alpha-glucosidase was determined. A comparison with the promoter regions of other Aspergillus amylase genes indicated that there are thre

An autonomously replicating plasmid is expected to increase the frequency of Aspergillus transformation. To construct this type of plasmid, we developed a rapid method of re-isolating autonomously replicating plasmids from Aspergillus transformants.

Hiochi-bacterial plasmids were screened. Many hiochi-lactobacilli had plasmids of several molecular sizes, whereas only a few true hiochi-bacilli had just one or two plasmids. A 4.7 kb cryptic plasmid in hiochi-lactobacilli homo-fermenter A-1 strain
