The carotenoid absorption band of each purified preparation of antenna complexes was similar, in shape and location, to that of the membranes from which that particular preparation was derived. Besides, the similitude was kept unchanged after organic solvent extraction of the preparations (not shown). Then, it seems that the incorporation of carotenoid pigments to the antenna complexes in vivo is a nonspecific process. The detection of spirilloxanthin as the sole carotenoid of previously analyzed antenna preparations of the same microorganism seems to be accidental and, as suggested by Duysens (in Cogdell and Thomber, 1979, pp. 77), probably due to the use of old, spirilloxanthin enriched cultures as the starting material for complex solubilization.

For the incorporation of carotenoids, RCs from Rb. sphaeroides R-26.1 are introduced into a small (8 inl) vial, and 1% of Triton X-100 in 15 mM Tris buffer, pH 8, is added to obtain a final solution of 0.67% Triton X-100. A 15-fold molar excess of the...

Dietary incorporation of carotenoids into the skin and fat of broilers is relatively fast. Broiler meat birds can be supplemented for 4 weeks out of the 8-week growing period with satisfactory results (Marusich and Bauernfiend, 1981). Carotenoids are generally supplemented at higher levels in grower and finisher feeds than in starter rations. Marusich and Bauernfiend (1981) reported that a range of 2.2-11 mg carotenoid/...
