This study investigated an alternative nutrient source arising from anaerobically digested Tetraselmis sp. effluent (MDE) as a nutrient feed stock to form a closed loop nutrient system. To determine MDE suitability the following factors were observed: growth, lipid content, and the bacterial diversity. MDE was diluted according to the concentration of NH4+ content (20, 40, 60, 80 mg/L) and compared against F/2 medium a standard medium for Tetraselmis sp. The growth rate on the MDE medium was not as rapid as the F/2 medium and the less diluted MDE correlated (R-2) with lower total lipid contents (R-2, 0.927), additionally acyl carrier proteins (ACP) gene expression rates displayed lower gene expression within MDE treatments. Lastly, higher concentrations of MDE were correlated with a higher bacterial diversity throughout the investigation. The suitability of MDE as a nutrient supplement for the production of Tetraselmis sp. biomass and lipid is feasible. (C) 2014 Elsevier Ltd. All rights reserved.
