THE EFFECT OF SPECTRAL LIGHT COMPOSITION ON PHOTOBIOLOGICAL CHARACTERISTICS OF ALGA ISOCHRYSIS GALBANA
Keywords:
microalgae, chromatic adaptation, growth rates, light absorption by algae, C / Chl a ratioAbstract
The carbon and nitrogen contents in the cells of Isochrysis galbana culture were decreased during the adaptation to blue and green light, in relation to white light. Growth rates were approximately equal on the white, blue, green and red light. The spectral light composition also did not influence on light absorption by algae, organic carbon / nitrogen ratio and carbon / pigment chl а ratio in the cells of I. galbana culture.
