Cellular Composition Changes and Nitrogen Uptake under Extra-Limited Nitrogen Conditions by Thermosynechococcus sp. CL-1 Carbon Biofixation by Tseng Chi-Ming, Ko Tzu-Hsing, Hsueh Hsin-Ta, Chen Hsing-Hui, Ray Dah-Tong, Shen Yun-Hwei, Chu Hsin

“…Maximum lipid productivity of about 150 mg L−1 d−1 is obtained while the CO2 uptake rate is 917 mg L−1 d−1 at a dilution rate of 0.06 h−1 when both carbon and nitrogen sources are not limited. With high range of nitrogen concentrations batch culture test, TCL-1 reveals extra-high affinity on nitrogen source under limited carbon source conditions since the affinity constant is 0.12 mM. …”
