FPA and EGA levels in cultures grown on α-cellulose (20 g l−1) under anaerobic conditions (labelled ‘Anaerobic’) or under initially anaerobic conditions followed by aerobic conditions (labelled ‘Aerobic’). The broken vertical line indicates the switch to aerobic conditions in ‘Aerobic’ at 72 h. FPA levels below the detection limit are shown as zero. Symbols: (open square) FPA ‘Aerobic’, (filled square) FPA ‘Anaerobic’, (open triangle) EGA ‘Aerobic’ and (filled triangle) EGA ‘Anaerobic’
