Bioremediation and Biomass Production with the Green Microalga Chlorococcum humicola and Textile Mill Effluent (TE)
The study aimed at possible bioremediation of textile mill effluent (TE) and simultaneous production of useful biomass. The green, unicellular microalga, Chlorococcum humicola was grown in TE. Even in undiluted effluent, this alga reduced several important effluent parameters from 9 to 94% in 6 days...
