Different light intensity on Messastrum gracile growth under phototrophic cultivation in laboratory.

The present research evaluates the effects of three different lighting intensities, 60 (control), 30 and 120 µmol photons m s on Messastrum gracile growth. The observations indicated that a light intensity of 60 µmol photons m s resulted in higher cell density during experimental period. The light intensity of 120 µmol photons m s had a strong negative impact on M.
