Quantification of the calorific content of microalgae is critical in studies of energy flow, trophic partitioning, plant/herbivore interactions in aquaculture and biomass production for biofuels. We investigated the calorific value and biochemical composition of Chlorella vulgaris at different phosphorus (P) concentrations (6.0x10(-7), 2.3x10(-6) and 2.3x10(-4)molL(-1) P). As expected, the control (2.3x10(-4)molL(-1) P) supported better growth than P limited treatments. Biomolecules like total carbohydrates and lipids accumulated under P limitation, which significantly correlated with high calorific values. Lipid class composition showed that triacylglycerols were the most accumulated under P limited conditions. The calorific value reported under control conditions (13.78kJg(-1)) was less than those obtained under P limitation (30.47-33.07kJg(-1)). The highest calorific value with less growth retardation was obtained at 2.3x10(-6)molL(-1) P. (AU)
