Abstract
Autotrophic cells of Chlamydomonas reinhardii and Chlorella pyrenoidosa, cultured in blue light, have a significant higher content of phosphate compared with cells cultured in the red light with equal dry mass. The greatest effect was observed in the acid-insoluble polyphosphates. The blue light-dependent enhancement was less pronounced in the acid insoluble stable and the acid soluble labile phosphate. In conditions of nitrogen deficiency the polyphosphates contain nearly all the phosphate additionally incorporated in the blue light. The enhancement of 32P-incorporation, compared with the red light, is delayed and more distinct after about 30 min. Blue light cells have a higher content of ATP. The interaction between the blue light-dependent increase of the ATP- and polyphosphate pool is discussed.
