Brettanomyces bruxellensis: effect of oxygen on growth and acetic acid production

  title={Brettanomyces bruxellensis: effect of oxygen on growth and acetic acid production},
  author={M. G. Aguilar Uscanga and M. L. Delia and Pierre Strehaiano},
  journal={Applied Microbiology and Biotechnology},
The influence of the oxygen supply on the growth, acetic acid and ethanol production by Brettanomyces bruxellensis in a glucose medium was investigated with different air flow rates in the range 0–300 l h–1 (0–0.5 vvm). This study shows that growth of this yeast is stimulated by moderate aeration. The optimal oxygen supply for cellular synthesis was an oxygen transfer rate (OTR) of 43 mg O2 l–1h–1. In this case, there was an air flow rate of 60 l h–1 (0.1 vvm). Above this value, the maximum… CONTINUE READING
