Development and characterization of a Nannochloropsis mutant with simultaneously enhanced growth and lipid production

Table 1 Specific growth rate and FAME analysis of WT N. salina and Mut68

Strain	Specific growth rate (day⁻¹)	FAME content (%)		FAME titer (g/L)		FAME productivity (mg/L/day)
		Day 8	Day 12	Day 8	Day 12	Day 8	Day 12
WT	0.57 ± 0.12	13.0 ± 1.4	24.9 ± 6.3	0.16 ± 0.03	0.58 ± 0.17	19.5 ± 3.5	48.3 ± 14.4
Mut68	0.87 ± 0.10*	17.4 ± 1.7**	32.8 ± 4.7*	0.27 ± 0.05**	0.94 ± 0.30*	34.1 ± 6.6**	78.3 ± 24.8*

The data show the mean value of 4 samples. As determined by Student’s t-test, significant differences are indicated by asterisks (* p < 0.05, ** p < 0.01, *** p < 0.001). Specific growth rate was calculated as (μ/day) = 1n (X₂ – X₁)/(t₂ – t₁), X₁ and X₂ are the initial and final biomass and t₁ and t₂ are the initial and final culture times
