Abstract
Light intensity adaptation (20-565 microeinsteins/m2 per sec) of M. aeruginosa (UV-027) was examined in turbidostat culture. Chlorophyll a and phycocyanin concentrations decreased with increasing light intensity while carotenoid, cellular C and N contents did not vary. Variation in the number but not the size of photosynthetic units per cell, based on chlorophyll a/P700 ratios, occurred on light intensity adaptation. Changes in the numbers of photosynthetic units partially dampened the effects of changes in light intensity on growth rates.This publication has 16 references indexed in Scilit:
