Abstract:
Strain F-5 and several other strains of Halobacteria were isolated from saltern pool of Xiamen, China. Strain F-5 is Gram-negative rod and obligate aerob'e. Optimum salt concentration for strain F-5 growth is 18% to 26% NaCl and no growth below 14% NaCl. And strain F-5 can produce carotenoids pigments. Therefore, strain F-5 is considered as one member of extreme Halogacteria.Natural pigment F-5-C1 is mainly produced by strain F-5. F-5-C1 is obtained as a purple crystal and soluble in organic solvents, but no soluble in water. F5-C1 exhibits a molecular ion by EI-MS at m/z 536. 9, corresponding to the formula C40H56. The UV and IR spectra of F-5-C1 is identical with that of fj-carotene (E. Merck product), which was isolated from carrot. These informations coupled with 'HNMR, 13CNMR and MS spectral data allowed us to consider that F-5-C1 is identified with B-carotene. And this is the first report on B-carotene produced by one strain of Halobacteria.
