Isolation and characterization of Chlorella sp. mutants with enhanced thermo- and CO2 tolerances for CO2 sequestration and utilization of flue gases

Table 1 Carbohydrate and lipid production by Chlorella vulgaris ESP-31 mutants grown in simulated flue gas and high temperature

Strain	Carbohydrate content (%)^a	Carbohydrate production (mg/L)^b	Lipid content (%)^c	Lipid production (mg/L)^d
Wild type	–	–	3.72 ± 0.002	5.57 ± 0.70
283	29.98 ± 1.71	234.53 ± 18.39	17.84 ± 0.016**	139.31 ± 9.69**
359	24.02 ± 1.04	152.71 ± 4.23	17.49 ± 0.030*	111.03 ± 17.27*

Each datum indicates the mean ± SD from two experiments
* P < 0.05 and **P < 0.01 were statistically significant as compared with Chlorella vulgaris ESP-31 wild type
–, no data because the cells were dead
^aCarbohydrate content (%) = (carbohydrate dry weight/biomass dry weight) × 100%
^bCarbohydrate production (mg/L) = (Max. biomass production × carbohydrate content)/100 × 1000
^cLipid content (%) = (lipid dry weight/biomass dry weight) × 100%
^dLipid production (mg/L) = (Max. biomass production × lipid content)/100 × 1000
