SYNCHRONOUS CULTURE OF CHLORELLA WITH SPECIAL REFERENCE TO THE PROCESSES OF ASSIMILATION OF POTASSIUM, MAGNESIUM AND IRON

[摘要] (1) By using the technique of synchronous culture of Chlorella, the changes in contents of potassium, magnesium and iron in successive developmental stages of algal cells were investigated.(2) In percent of dry weight of cells, the content of potassium remained relatively constant throughout the life cycle, whereas the contents of magnesium and iron were lower at the growing stages (from the stage of "nascent dark cells" to the stage of "immature light cells") and higher at the ripening stage (the stages of light cells).(3) A brief discussion was made in an attempt to relate the data obtained with earlier observations regarding the changes in contents of various other cell materials in the life cycle of Chlorella cells.
