Effect of validated variants on propanol formation. Simplified synthesis pathway of fermentative aromas connected to threonine metabolism (a). Allelic effect of the involved enzymes Alp1 and Nrg1 on the formation of volatiles derived from α-ketobutyrate as determined by RHA (b). Concentrations are given in relation to the heterozygote of the parental strains MTF2621 and MTF2622. (p-value: ns (not significant) > 0.05, * ≤ 0.05, ** ≤ 0.01)
