Studies on photosynthetic bacteria. 2. Studies on chlorophyll and growth in Chlorobium limicola and Chlorobium thiosulfatophilum

Abstract

Studies were conducted on Chlorobium limicola and Chlorobium thiosulfatophilum for chlorophyll and growth. Spectrophotometric readings at different wave-lengths and TLC showed two types of chlorophylls (a and b). Chlorophyll contents under different growth conditions were also observed. Growth curve was studied by the turbidity assay procedures. The results demonstrated that growth is slow. Maximum growth was observed after 75 hr
