Growth (Cbiomass, a) and lipid accumulation (Clipid, b) of Graesiella sp. WBG-1 in a 200 m2 raceway pond. The mixotrophic cultivations (blue up triangle) were operated by SPMC method in May 14–28/2015. Down arrows indicate the first supplementation of acetate. Data of the phototrophic cultivation (green circle) are cited from our earlier study [24]. Error bars show the standard deviations of at least three measurements
