Strains and medium
All strains used in this study are compiled in Table 1 .S. cerevisiae BTCC3 (haploid) was obtained from Indonesian Culture Collection (InaCC, Cibinong Science Center, BRIN, Indonesia). This strain and its derivatives were cultivated using a yeast/peptone/dextrose (YPD) medium (20 g∙L-1 Bacto peptone [BD, San Jose, CA], 10 g∙L-1 Bacto yeast extract [BD], and 50 g∙L-1 glucose [BD]).Escherichia coli JM109 (Takara Bio, Shiga, Japan) was used for cloning. Luria-Bertani medium (10 g∙L-1 tryptone [Nacalai, Japan], 5 g∙L-1 yeast extract [BD], and 10 g∙L-1 sodium chloride [Nacalai tesque Inc., Japan]) was used for cultivation.
