Effects of various organic carbon sources on the growth and biochemical composition of Chlorella pyrenoidosa
Abstract
The aim of this study was to investigate the effects of various organic carbon sources (glucose, galactose, fructose, sucrose, maltose, lactose and starch) on the growth and biochemical composition of Chlorella pyrenoidosa. Monosaccharides were found to exert stronger stimulative effects on the algal growth than disaccharides and starch. After 10-day culture, addition of 0.5-5.0 g L(-1) glucose and galactose significantly reduced the cellular protein contents by 27.7-63.7% and 22.6-60.5%, respectively, and significantly increased the carbohydrate contents by 103.2-266.5% and 91.9-240.0%, respectively. However, addition of 0.5-5.0 g L(-1) disaccharides and starch did not significantly affect the contents of lipid, protein and carbohydrate. Similar to the normal nitrogen condition, the cellular biochemical composition was not significantly affected by addition of 3.0 g L(-1) disaccharides and starch under the low nitrogen condition. Finally, the significance of this work in the biotechnological application of mixotrophic cultivation of C. pyrenoidosa was further discussed.

Under mixotrophic conditions, C. pyrenoidosa attained higher cell densities on glucose than on galactose or fructose when 5.0 g/L of each sugar was added to Bold's Basal Medium.
“Under mixotrophic conditions, C. pyrenoidosa attained higher cell densities on glucose (9.7 × 10 7 cells mL -1 ) than on galactose (7.5 × 10 7 cells mL -1 ) or fructose (5.8 × 10 7 cells mL -1 ), when 5.0 g L -1 of each sugar was added to Bold's Basal Medium (BBM).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
