AUXOTROPHY AND HETEROTROPHY IN MARINE LITTORAL DIATOMS
Canadian Journal of Microbiology, 1960Forty-four pure cultures of marine littoral diatoms (43 pennate and 1 centric) have been studied to determine (a) whether any accessory organic factors (vitamins) are essential for growth in light, and (b) whether the cells can grow in darkness using glucose, acetate, or lactate as substrates.Six isolates were shown to require thiamine as sole growth ...

Towards universal synthetic heterotrophy using a metabolic coordinator
Metabolic Engineering, 2022ABSTRACT Engineering the utilization of non-native substrates, or synthetic heterotrophy, in proven industrial microbes such as Saccharomyces cerevisiae represents an opportunity to valorize plentiful and renewable sources of carbon and energy as potential inputs to biotechnological

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.

Facultative Heterotrophy in Some Chlorococcacean Algae
Science, 1961All known species of the genera Bracteacoccus , Spongiochloris , and Dictyochloris , and some of the species of Neochloris and Spongiococcum are capable of growing heterotrophically in darkness in a glucose-salts medium ...

The evolutionary ecology of myco‐heterotrophy
New Phytologist, 2005SummaryNonphotosynthetic mycorrhizal plants have long attracted the curiosity of botanists and mycologists, and they have been a target for unabated controversy and speculation. In fact, these puzzling plants dominated the very beginnings of the field of mycorrhizal biology.

Autotrophy and heterotrophy in root herniparasites
Trends in Ecology & Evolution, 1989More than 3000 species of flowering plants are at least partially parasitic, acquiring water and solutes from the host via haustoria. More than one third of all parasitic angiosperms - the root hemiparasites - possess green leaves and root systems.

Frontiers in Plant ScienceIn the transcriptome analysis, the CC-125 strain was cultured in photoautotrophy for 12 hours, then collected 2×10^7 algal cells (for the P12h group). The remaining CC-125 cultures were rinsed three times with TAP medium and immediately transferred to a ...

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.

Screening Arthrospira (Spirulina) strains for heterotrophy
Journal of Applied Phycology, 2005Thirty-five clonal, axenic Arthrospira strains were screened for their ability to grow heterotrophically on six carbon sources (20 mM). Glucose (34 strains) and fructose (24 strains) were the only substrates permitting growth in the dark. In some assays, however, not every replicate grew and, in at least one strain (D867), repeat assays over 2 years on
