Aerobic growth of the yeast Brettanomyces intermedius CBS 1943 in batch culture on a medium containing glucose and yeast extract proceeded via a characteristic pattern. In the first phase of growth glucose was fermented to nearly equal amounts of ethanol and acetic acid. After glucose depletion, gro
