alpha-Acetolactate decarboxylase (ALDC) gene from Acetobacter aceti ssp. xylinum has several possible initiation codons in the N-terminus. To determine the initiation codon of the ALDC giving the highest expression levels, glyceraldehyde-3-phosphate dehydrogenase (GPD) promoter was linked just upstream of each possible initiation codon. The ALDC whose translation starts 130 bp downstream from the first ATG codon had the highest activity in yeast cells. When expression levels of the ALDC gene were compared using three strong yeast promoters of glycolytic genes, alcohol dehydrogenase I (ADC1), phosphoglycerate kinase (PGK) and GPD, the GPD promoter was the strongest. The ALDC gene was integrated in a ribosomal RNA gene of a brewer's yeast by co-transformation with an expression plasmid of G418-resistance gene. The laboratory-scale growth test confirmed that the total diacetyl concentration was reduced in wort.

An integration plasmid pA15-PET for expression and secretion of beta-Endoglucanase I (EG I ) in yeast was constructed by insertion of EG I cDNA between yeast alcohol dehydrogenase promoter and terminator region. The plasmid contained part of yeast rDNA sequence, which was used as a homologous fragment for integration. The EG I cDNA was introduced into an engineered brewing yeast BE9711 containing alpha-acetolactate decarboxylase (alpha-ALDC) encoding gene and integrated onto its rDNA sequence of chromosomal DNA by co-transformation of pA15-PET and a YEP type plasmid pA15TXR carrying G418 resistance. The stable engineered brewing yeast expressing intracellulase alpha-ALDC and extracellular EG I simultaneously were obtained.
