Abstract
Abstract. Evaluation on the growth of Nannochloropsis sp. in the biogas effluent of tapioca industry (MEBIT) has been conducted. The Nannochloropsis sp. that isolated from marine biota in Lampung area was acclimated in the 1, 3, and 6% MEBIT. The evaluation of Nannochloropsis sp. was using cell density at 750 nm, chlorophyll a concentration and biomass yields. The Nannochloropsis sp was growth well in the 6% (v/v) MEBIT based on the color of the culture. The OD of Nannochloropsis sp on MEBIT obtained at 750 nm is about 0.14 to 1.48. The chlorophyll a concentration is about 1.27 to 13.51 mg / mL, whereas the concentration of the biomass is 0.311 g/L with a productivity of 0.019 gLˉ1 dˉ1 , it is higher than when it cultivates in the standard media (BG 11). The protein content in MEBIT is 30.65%, it is lower than in the BG 11 growth (36.41%) of the dry biomass.
