Heterotrophy and nitrate metabolism in a cyanobacteriumPhormidium uncinatum
Current Microbiology, 1990Nitrate-supported heterotrophic growth ofPhormidium uncinatum was achieved after repeated exposure to glucose in the presence of a photosystem (PS) II inhibitor. Nitrate and glucose utilization as well as activities of their metabolizing enzymes were measured comparatively in photoautotrophic and heterotrophic cells.

Heterotrophy by Plankton in Three Lakes of Different Productivity
Nature, 1972THE utilization of dissolved organic compounds by heterotrophic microorganisms is an important process in the aquatic carbon cycle and in the functioning of aquatic ecosystems in general1. It has been hypothesized that the only significant uptake of naturally occurring dissolved organic compounds by plankton is carried out by heterotrophic bacteria and

Evidence for facultative heterotrophy in cultured zooxanthellae
Marine Biology, 1987The locus of symbiotic dinoflagellates within host cells provides a habitat which could potentially be exploited by the alga through heterotrophic uptake of host-derived organic substrates. Using zooxanthellae (Symbiodinium sp.) isolated from the tropical sea anemone Aiptasia pulchella collected from Kaneohe Bay, Hawaii, the effect of various potential

Experimental evolution of heterotrophy in a green alga.
Evolution; international journal of organic evolution, 2013Laboratory populations of a green alga cultured in the dark with an organic substrate evolved into efficient heterotrophs with faster growth, higher fitness, and increased responsiveness to substrate concentration. Their phenotypes were almost entirely attributable to selection, rather than to history or ancestry.
