TABLE 3.

Relative amounts of the LH1 BCh1 and carotenoids in isolated chromatophores^a

Strain	Growth	Relative intensity (%) (±10%) of the absorption maximum at:
		880 nm (or 873 nm)b	512 nmc
S1	Anaerobic	100	100
S1	Semiaerobic	88	83
SPUHK1	Semiaerobic	86	83
SPUHK2	Semiaerobic	79	76
ST2	Semiaerobic	88
G9	Anaerobic	100
GPUHK1	Semiaerobic	72
GPUHK2	Semiaerobic	78

^aValues were normalized to identical amounts of protein, as judged from the A₂₈₀.

^bThe wavelength maximum in parentheses corresponds to the Q_y absorption band of the carotenoid-less strains.

^cCarotenoid absorption maximum.
