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 ...

Cyanophycinase is required for heterotrophy in cyanobacteria. [PDF]
J Biol ChemCyanophycin 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

Diazotroph-Derived Nitrogen Assimilation Strategies Differ by Scleractinian Coral Species
Frontiers in Marine Science, 2021 Reef-building corals generally thrive in nutrient-poor tropical waters, where among other elements, nitrogen (N) availability often limits primary productivity.

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.

Crenarchaeal heterotrophy in salt marsh sediments [PDF]
The ISME Journal, 2014 Abstract Mesophilic Crenarchaeota (also known as Thaumarchaeota) are ubiquitous and abundant in marine habitats. However, very little is known about their metabolic function in situ. In this study, salt marsh sediments from New Jersey were screened via stable isotope probing (SIP) for heterotrophy by amending with a single 13C-labeled ...

Microorganisms, 2021 The association between corals and photosynthetic dinoflagellates is one of the most well-known nutritional symbioses, but nowadays it is threatened by global changes.

Journal of General Microbiology, 1953 SUMMARY: Forty-two bacteria-free cultures of pennate diatoms from fresh water or soil were tested for ability to grow heterotrophically with glucose as the sole carbon source. Thirteen of these isolates proved capable of growth under these conditions.

Energetics and Application of Heterotrophy in Acetogenic Bacteria [PDF]
Applied and Environmental Microbiology, 2016 ABSTRACTAcetogenic bacteria are a diverse group of strictly anaerobic bacteria that utilize the Wood-Ljungdahl pathway for CO2fixation and energy conservation. These microorganisms play an important part in the global carbon cycle and are a key component of the anaerobic food web.

Ingestion of Diazotrophs Makes Corals More Resistant to Heat Stress
Biomolecules, 2022 Over the past decade, coral bleaching events have continued to recur and intensify. During bleaching, corals expel millions of their symbionts, depriving the host from its main food source.
