A blue-green algae spiru1ina fusiformis was grown under various light regimes in a laboratory-scale experiment. A 500 watt halogen lamp was employed as the light source, while the light variation of 2,000 lux, 4,000 lux, 6,000 lux, 8,000 lu,c, and 10,000 lux was obtained by placing a series of 2 L experimental bottles at various distances. The growth medium used was a modified-Zarrouk medium wi…
