TABLE 1.

Free fatty acid composition of Cyanothece sp. PCC 8801

Fatty acids were extracted from frozen cyanobacterial cells, methylated, and analysis of the methyl ester derivatives was performed via GC as described under “Experimental Procedures.” The fatty acids were characterized by co-elution of authentic standards. The values presented here are the average of three independent measurements.

Fatty acid	Proportion of total fatty acids
	%
16:0	15.0
16:1(n-7)	7.8
18:0	9.1
18:1(n-9)	14.9
18:2(n-6)	53.2
