Fig. 6

Saccharomyces in vivo Dgd1 activity. A Decarboxylation half-reaction is carried out by dialkylglycine decarboxylase [13, 14]. B Growth and AIB consumption curves showed by the induced protein producer strains (left), AIB consumption, and acetone production after 48 h (right). C alt1 IFO1802 mutant is unable to grow in the presence of AIB. Ala: 10 mM L-alanine; Gln: 10 mM L-glutamine; AIB: 10 mM 2-aminoisobutyric acid. The error bars are the standard deviation of three biological replicas. Statistical differences were obtained through one-way ANOVA analysis. The raw data and statistical analyses are given in Additional file 12
