Batch study was used for the production of laccase enzymes
under submerged condition. The medium was autoclaved at 121 ◦C
for 20min and inoculated after cooling to 30 ◦C. Enzyme production
medium contained groundnut shell of 1003–1205msize (9 g) and
dry cyanobacterial biomass (1 g) in 100ml of carpet industry dyeing
effluent.
