Some data on the growth physiology of Chlorella studied by the technique of synchronous culture

Synchronous Cultures of Algae

“…Changes in content of protein and related substances in synchronized algal cells have been studied by many workers using Chlorella (51,60,64,115,145,158,162,163,194), Scenedesmus (106,107,121,122), and Chlamydomonas (79, 217). Using C. ellipsoidea, a most extensive investigation was made by Kanazawa (76) on the changes in content of free and bound forms of amino acids during the algal life cycle.…”

A heterotrophic synchronous culture of Chlorella.

“…The increase in the DNA content in the middle of HOP appeares to arise from the replicative synthesis of the algal chloroplast DNA, followed by that of nuclear DNA, as was proved in PSC (3,8). Correspondingly, the content of chlorophyll increased significantly after the middle of HOP, but was reduced during LOP to the level at the beginning of the cell cycle.…”

Changes of Lipid and Carbohydrate Contents in Chlorella Cells During the Sulfur Starvation, as Studied by the Technique of Synchronous Culture

“…The cells used for analyses were obtained by the method of synchronous culture reported in our previous paper (6).…”
