<P><B>Abstract</B></P> <P>The cultivation of <I>Chlorella</I> sp. TISTR 8411 on biogas effluent of seafood processing wastewater was investigated. <I>Chlorella</I> sp. biomass was used for biogas production by anaerobic co-digestion with seafood processing. <I>Chlorella</I> sp. biomass cultivated on 50, 60, 70, 80, 90, and 100% of biogas effluent was 0.184, 0.121, 0.061, 0.048, 0.039, and 0.032 g/L, respectively. The highest growth of <I>Chlorella</I> sp. biomass was 0.184 g/L from 50% biogas effluent. Methane yield from anaerobic co-digestion of seafood processing wastewater with 10, 20, 30, 40, and 50% v/v <I>Chlorella</I> sp. biomass was 131, 152, 173, 188 and 193 ml CH<SUB>4</SUB>/gVS, respectively. Methane yield from <I>Chlorella</I> sp. biomass was 44 ml CH<SUB>4</SUB>/gVS. Methane yield from seafood processing wastewater was 18 ml CH<SUB>4</SUB>/gVS. 10 times of methane yield was improve in anaerobic co-digestion seafood processing wastewater with <I>Chlorella</I> sp. biomass at 40 and 50 % v/v. Anaerobic co-digestion seafood processing wastewater with <I>Chlorella</I> sp. biomass has great potential for biogas production.</P>
