Effects of Various Nitrogen Sources on the Growth and Biochemical Composition of <I>Chlorella</I> sp.

Highlight Research Each species of microalga has a preferable nitrogen source for their optimal growth. The sources in the grown media affected growth rate and biochemical composition Chlorella FNUB01. (NH2)2CO (urea) was found to be best alternative For producing 1 g FNUB01, use urea reduced cost medium by 72.6%. Abstract sp. is potential microalgae produced commercially feed, accelerator, immuno-modulator fish shrimp culture. This study aimed evaluate various on growth, biomass production, used this were (NH2)2CO, potassium nitrate (KNO3), ammonium (NH4NO3). Sodium (NaNO3) as control it part commercial BG-11. Generally, chemical green grew better urea-containing which accounted 1.5 times concentration that cultured BG-11 (40 x106 cells. mL-1). Meanwhile, experienced lowest when NH4NO3-containing medium. productivity FNUB01 (0.93 g.L-1) comparable those with NaNO3 N source. A similar pattern recorded protein, chlorophyll, carotenoid content these contents availability Urea an low-cost culture Replacement could reduce
