For the chlorophyll decrease and formation of Chlorolla variegata by Glucose-Culture (II) Influence of temperature and pH

Chlorella Variegata Beijerinck 의 Glucose 배양에 있어서의 Chlorophyll 증감관계에 관한연구 (제 2 ) .pH 의 영향에 대한

I studied about temperature and pH concentration having influence upon chlorophyll decrease on the Glucose culture of Chlorella variegata Beijerinck(211/10a). I cultured under $25^{\circ}C$(standard), $15^{\circ}C$ and $35^{\circ}C$ and compared with each other. The culture of $15^{\circ}C$ didn't have any large difference with the standard culture($25^{\circ}C$) but the culture of $35^{\circ}C$ had a large amount of chlorophyll decrease without carbohydrate accumulation, stimulation of cell division and nitrogen-deficiency. Chlorella variegata had optimum pH 6.5-7 and was a little weak in all phenomenon under pH 8 rather than under pH 6.5-7. Under pH 5 they had deep chlorophyll decrease without phephytin.
