Batch kinetics of nutrients removal for palm oil mill effluent and recovery of lipid by Nannochloropsis sp

Batch experiments were investigated for the effect of initial nutrients concentration of palm oil mill effluent (POME) on nutrients removals, growth rate, and lipid content recovery by Nannochloropsis sp. Bio-kinetic coefficients, k; reaction rate constant, Km, half-saturation constant, and Y, yield...
