Calothrix elenkenii was evaluated for accumulation of chlorophyll, beta-carotene and phycobiliproteins when grown under light-dark cycles and darkness, in the presence of glucose. Highest values of beta-carotene, chlorophyll, proteins and acetylene-reducing activity were recorded when the organism was grown in the presence of glucose under light-dark cycles after 15 d of incubation. The presence of glucose in the medium stimulated pigment production, especially of beta-carotene and chlorophyll, which may be due to increased energy-linked assimilation and ATP production. The photoheterotrophic potential of C. elenkenii can be exploited in value addition for increased and economic production of pigments.
