Fig 2. Metabolic output profiles of Saccharomyces spp on media containing formic acid (0–20 mM) incubated at 30°C under anaerobic conditions.

(A) Control (0 mM) media without formic acid. (B) Formic acid 20 media. (C) Duration of lag phase in PM at formic acid 0,10,15 and 20 mM media. (D) Maximum redox signal intensity after 90 hours at formic acid 0, 10, 15, 20 and 25 mM media. Error bars represent the standard deviation of 3 replicates (Biolog unit = redox signal intensity).
