Abstract
The consumption and utilization of a series of carbohydrates by a strain of Chlorella pyrenoidosa under different conditions of culture was examined. Only glucose, fructose and mannose were avidly consumed; galactose was consumed in small quantities. Light was highly stimulatory for the consumption of sugars. The carbohydrates assimilated were polymerized to starch; this induced gigantism in the organisms, a considerable increase in the dry weight, and inhibition of division.
