Heterotrophy among Cyanobacteria

ACS Omega, 2023
Cyanobacteria have been studied in recent decades to investigate the principle mechanisms of plant-type oxygenic photosynthesis, as they are the inventors of this process, and their cultivation and research is much easier compared to land plants. Nevertheless, many cyanobacterial strains possess the capacity for at least some forms of heterotrophic ...

Oxygen and heterotrophy affect calcification of the scleractinian coral Galaxea fascicularis. [PDF]

PLoS ONE, 2012
Heterotrophy is known to stimulate calcification of scleractinian corals, possibly through enhanced organic matrix synthesis and photosynthesis, and increased supply of metabolic DIC.

Methodological tests of a heterotrophy index for aquatic ecosystems [PDF]

Brazilian Journal of Biology, 2003
Experiments in glucose mineralization were carried out to investigate the effects caused by natural forcing functions on both the decomposition rates and heterotrophy capacity of aquatic ecosystems. In addition, the methodology used could show connections between mineralization rates measured in both laboratory and field work with those measured in ...

Spontaneous evolution of heterotrophy in cultured dinoflagellate algae

Current Biology
Acquisition of chloroplasts by an early eukaryote and their subsequent spread across eukaryotes is well understood. However, evolution can be undone, and many important lineages (especially in the Apicomplexa) have lost photosynthesis, returning to heterotrophy.

Heterotrophy mitigates the response of the temperate coral [PDF]

, 2016
Anthropogenic 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.

Trophic Diversity in Duckweed: Mixotrophy, More Than the Sum of its Extremes. [PDF]

Adv Sci (Weinh)
In the context of rising DOC in aquatic environments, mixotrophic duckweed may impact carbon cycling by acting as either a carbon sink, as they absorb CO2 through photosynthesis, or a carbon source, as they release CO2 through respiration of absorbed DOC, which depends on DOC concentration, light availability, temperature, and other environmental ...

Changes in photosynthesis and grazing facilitate growth of a mixotrophic protist under ocean acidification and warming. [PDF]

New Phytol
Grazing rates of Ochromonas CCMP2951 expressed as carbon obtained per mean cell volume (a) and Caut/het‐photosynthetically fixed carbon divided by carbon obtained through grazing (b) in the four experimental treatments. Summary Mixotrophic protists capable of both photosynthesis and phagotrophy are key members of marine plankton communities.

Cyanophycinase is required for heterotrophy in cyanobacteria. [PDF]

J Biol Chem
Cyanophycin is a biopolymer of arginine (Arg) and aspartate, and it is found in various prokaryotes. Two key enzymes of cyanophycin metabolism are cyanophycin synthase (CphA), producing cyanophycin, and cyanophycinase (CphB), catalyzing the first step of cyanophycin degradation. CphB is a well-conserved enzyme found in the majority of cyanobacteria and

Glacial melt disturbance shifts community metabolism of an Antarctic seafloor ecosystem from net autotrophy to heterotrophy [PDF]

, 2021
Climate change-induced glacial melt affects benthic ecosystems along the West Antarctic Peninsula, but current understanding of the effects on benthic primary production and respiration is limited.

Screening Suitability of Northern Hemisphere Algal Strains for Heterotrophic Cultivation and Fatty Acid Methyl Ester Production

Molecules, 2020
Rapid rises in atmospheric CO2 levels derived from fossil fuel combustion are imposing urgent needs for renewable substitutes. One environmentally friendly alternative is biodiesel produced from suitable microalgal fatty acids.
