Summary Lemna minor L. and Wolffia brasiliensis Weddell can use sucrose to support heterotrophic growth in darkness and photomixotrophic growth in the light, but each is killed by galactose in the medium. Spirodela punctata (G. F. W. Meyer) Thompson growth on sucrose and galactose was indistinguishable. L.

Microbially Mediated Mineral Carbonation: Roles of Phototrophy and Heterotrophy
Environmental Science & Technology, 2011Ultramafic mine tailings from the Diavik Diamond Mine, Canada and the Mount Keith Nickel Mine, Western Australia are valuable feedstocks for sequestering CO₂ via mineral carbonation. In microcosm experiments, tailings were leached using various dilute acids to produce subsaline solutions at circumneutral pH that were inoculated with a phototrophic ...

Carbon Isotope Composition, Gas Exchange and Heterotrophy in Australian Mistletoes
Functional Ecology, 1994Photosynthesis, transpiration and carbon isotope ratios of 11 mistletoes and their hosts were measured in central and eastern Australia to test hypotheses regarding similarity of photosynthetic rate between host and parasite and significance of host xylem carbon as a contributor to parasite carbon gain. Differences in photosynthetic rates of mistletoes

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

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

Molecular assessment of heterotrophy and prey digestion in zooxanthellate cnidarians
Molecular Ecology, 2013AbstractZooxanthellate cnidarians are trophically complex, relying on both autotrophy and heterotrophy. Although several aspects of heterotrophy have been studied in these organisms, information linking prey capture with digestion is still missing.

Hypothesis on the Synchronistic Evolution of Autotrophy and Heterotrophy
Trends in Biochemical Sciences, 2018All life on earth requires a source of energy and organic carbon. There has been a continuous debate on whether autotrophic or heterotrophic metabolism came first. A very similar discussion exists concerning the advent of oxygenic photosynthesis and aerobic respiration.

Heterotrophy mitigates the response of the temperate coral
2016Anthropogenic increases in atmospheric carbon dioxide concentration have caused global average sea surface temperature (SST) to increase by approximately 0.11°C per decade between 1971 and 2010 - a trend that is projected to continue through the 21st century.
