Characterization of JSC-1 pigment composition. (A) Comparison of 77K fluorescence emission spectra measured for isolated thylakoid membranes from JSC-1 and Synechococcus sp. PCC 7002. Thylakoids were adjusted to equal Chl concentrations (5 μg/ml). The excitation wavelength was 440 nm, and each spectrum is the average of four individual measurements. (B) HPLC chromatogram of methanolic extract of JSC-1 cells. Top panel, full scale; bottom panel, magnification, ×10. Compounds are as follows: 1, synechoxanthin; 2, 2-hydroxy-myxoxanthophyll; 3, myxoxanthophyll (myxol-2′-fucoside); 4, nostaxanthin; 5, caloxanthin; 6, zeaxanthin; 7, cryptoxanthin; 8, echinenone; 9, β-carotene.
