Genes transcript abundance of nitrogen metabolism pathway in cells (a), nitrate consumption (b), qRT-PCR of nitrate reductase (c) and chlorophyll synthesis (d) of Chlorella PY-ZU1 cultivated under 15% CO2 versus air. Key enzymes of Calvin cycle were shown in boxes as enzyme commission (EC) numbers. Red box indicated an up-regulation, blue box indicated a down-regulation, and black box indicated no significant changes
