Tran et al. (1998) compared the CA production using differ-ent SSF systems, such as flask fermentation, tray fermentation and
rotating drum bioreactorfor CA production using pineapple waste
supplemented with 3% (v/w) MeOH. The authors concluded that
flask fermentation gives higher production of CA (14 g/100 g), when
compared to tray and rotating drum configurations (CA yield of
8 g/100 g) after 3 days. As compared to the previous studies con-ducted by other researchers using other agro-industrial wastes,
higher CA production was obtained using AP through SSF in the
present study. The present study also showed that MeOH has more
enhancing effect on CA production than EtOH as an inducer. Supple-mentation of EtOH and MeOH in the liquid medium resulted in
the pellet morphology rather than filamentous growth during the
fermentation which is considered best for CA production (Dhillon
et al., 2010). The present study also demonstrated that expensive
nutrient supplementation is not required for inexpensive agro-industrial wastes, which are already rich in carbon and other vital
nutrients required for CA production
