Ion beam breeding of "Sake Yeast"

Masubuchi, Takashi*; Sato, Katsuya; Narumi, Issey*; Kamiyama, Osamu*

Bio Industry, 30(7), p.65 - 71, 2013/07

Sake is a useful tool for promoting local industry, but sake consumption has been decreasing year by year. In Gunma prefecture, the Gunma industrial technology center has playing a central role in breeding original sake yeast. Furthermore, for quickly corresponding with the needs from market, JAEA have tried breeding of sake yeast by ion beam breeding technology for development of distinctive sake yeast and its practical use while closely coordinating with the Gunma industrial technology center. As a result, the high ethyl caproate producing novel sake yeast were obtained.

We have previously obtained high ethyl caproate producing Sake yeasts "No.227" and "No.1333" by ion beam breeding. The fatty acid synthase genes (${it FAS1}$ and ${it FAS2}$) and the fatty acid esterase genes (${it EHT1}$ and ${it EEB1}$) might be involved in the higher production of ethyl caproate in the mutant strains. In this study, to identify the mutation sites of the mutant strains, each gene locus was sequenced. For the ${it EHT1}$, ${it EEB1}$ and ${it FAS1}$ loci, all the mutations found in mutant strains are nonsense mutations, suggesting that these mutations did not involved in the higher production of ethyl caproate. On the other hand, strains No.227 and No.1333 carried G/A and A/A mutations in ${it FAS2}$ gene at nucleotide position 3,748 as heterozygous and homozygous states, respectively. This result strongly suggested that the higher production of ethyl caproate in strains No.227 and No.1333 is attributed to a dominant mutation in ${it FAS2}$ gene.
