From: Change in product selectivity during the production of glyceric acid from glycerol by Gluconobacter strains in the presence of methanol

  G. frateurii NBRC103465 G. frateurii THD32 G. oxydans IFO12528
Initial methanol (%, v/v) 0 1 0 1 0 1
GA (g/L) 28.2 ± 0.3 14.4 ± 0.7 23.0 ± 0.3 6.8 ± 0.3 18.8 ± 1.0 5.9 ± 0.4
DHA (g/L) 15.9 ± 0.6 38.0 ± 1.7 25.1 ± 5.8 24.1 ± 1.4 33.7 ± 0.3 51.9 ± 2.1
  1. Cells were cultivated in 30 mL of glycerol medium containing 170 g/L glycerol with methanol supplementation at 30°C for 96 h. The averages and standard deviations of two independent experiments are presented.
