Abstract

The feasibility of cultivating Chlorella vulgaris with wastewater containing high ammonia nitrogen concentrations was examined. The average specific growth rate of C. vulgaris was 0.92d^-1 at 17mgL^-1 NH₄⁺-N, but declined to 0.33d^-1 at NH₄⁺-N concentrations of 39-143mgL^-1. At 39mgL^-1 NH₄⁺-N, lipid productivity reached a maximum value (23.3mgL^-1d^-1) and dropped sharply at higher NH₄⁺-N levels, which demonstrated NH₄⁺-N should be controlled for biodiesel production. C16 and C18 fatty acids accounted for 80% of total fatty acids. Increasing NH₄⁺-N from 17 to 207mgL^-1 yielded additional short-chain and saturated fatty acids. Protein content was in positive correlation with NH₄⁺-N content from 17mgL^-1 (12%) to 207mgL^-1 (42%). Carbohydrate in the dried algae cell was in the range of 14-45%, with a peak value occurring at 143mgL^-1 NH₄⁺-N. The results demonstrate that product quality can be manipulated by NH₄⁺-N concentrations of the initial feeds. © 2012 Elsevier Ltd.
