Abstract: | Blue light was specifically required for the induction of carbonicanhydrase (CA) activity in Chlamydomonas reinhardtii. The enhancingeffect of blue light (460 nm) was saturated at energy fluencerate as low as 0.6-0.8 W/m2. The wavelength dependency curvehad a peak at 460 nm with no effect at wavelengths above 510nm, thus showing the strong similarities to other blue lightresponses in microalgae. CA induction was strongly inhibitedby UV irradiation at 280 nm. Experiments with the flavin quencher,potassium iodide, suggested that flavin is somehow involvedin CA induction. 1On leave from the Institute of Biological Sciences, Collegeof Arts and Sciences, University of the Philippines at Los Banos,4031 College, Laguna, Philippines.
