Isolation and characterisation of light harvesting complexes from bacteria of the genus Gemmatimonas

Abstract

Photosynthetic bacteria are highly abundant. The isolation and characterization of the light-harvesting complex from the Gemmatimonas phototrophica AP64T which belongs to the seventh phylum of the evolutionary important (bacterio)chlorophyll-containing bacteria are reported here. The purification of the complex was achieved by gel-filtration and electrophoresis. HPLC was used for identification of the pigments. The protein subunits were further identified by MS analysis.
