Abstract

SUMMARY: Two further groups of pigment mutants have been isolated from irradiated suspensions of the non-sulphur purple bacterium . Both contain the normal red carotenoid of the wild type, but in place of bacteriochlorophyll one group contains a derivative at the oxidation level of chlorophyll , and the other a pigment at the oxidation level of protochlorophyll. Both these groups are non-photosynthetic. All attempts to produce stable photosynthetic mutants containing a pigment absorbing at the same wavelengths as chlorophyll failed, although transient photosynthesis seemed to occur on several occasions. The relationship of these mutants to the biosynthetic pathway of bacteriochlorophyll suggested by Granick is discussed.
