The sludge was stored in a container and kept in the cold room at 4°C. The total suspended solids (TSS) of sludge were 0.73% (w/w). A 1% (w/w) TSS of the sludge was used as the major substrate and supplemented by wheat flour (3% w/v), which acts as an easily biodegradable carbon source for the initial growth of microbes for LiP production.
