Fig. 3From: Microalgal lipid production using the hydrolysates of rice straw pretreated with gamma irradiation and alkali solutionGrowth and lipid content of C. protothecoides from glucose and rice straw hydrolysate. Open and closed circles the residual glucose concentration and cell concentration in glucose, respectively. Open and closed triangles the residual glucose concentration and cell concentration in the rice straw hydrolysate, respectively. a heterotrophic culture condition with an equivalent glucose concentration of 10 g/L and b mixotrophic culture condition with an equivalent glucose concentration of 10 g/LBack to article page
