Fig. 3From: Process optimization for biosynthesis of pyruvate decarboxylase (PDC) and Neuberg’s ketol (PAC) from a novel Pichia cecembensis through response surface methodologyA Linear plot for PAC, PDC activity, and sugar consumed. B Box-Cox graphs for PAC (g/l), sugar consumed (% age, v/v), and PDC activity (U/ml). C Ramps depicting the impact of factors on pyruvate decarboxylase activity. Sugar conc. and incubation time have no effect. Temperature is significant and have positive impactBack to article page
