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

Endosymbiotic Evolution of Algae, Secondary Heterotrophy and Parasitism [PDF]
Biomolecules, 2019 Photosynthesis is a biochemical process essential for life, serving as the ultimate source of chemical energy for phototrophic and heterotrophic life forms. Since the machinery of the photosynthetic electron transport chain is quite complex and is unlikely to have evolved multiple independent times, it is believed that this machinery has been ...

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.

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 ...

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.

Microplastics ingestion and heterotrophy in thermally stressed corals [PDF]
Scientific Reports, 2019 AbstractRising sea temperatures and increasing pollution threaten the fate of coral reefs and millions of people who depend on them. Some reef-building corals respond to thermal stress and subsequent bleaching with increases in heterotrophy, which may increase the risk of ingesting microplastics.

Bleaching forces coral’s heterotrophy on diazotrophs and Synechococcus [PDF]
The ISME Journal, 2019 Abstract Coral reefs are threatened by global warming, which disrupts the symbiosis between corals and their photosynthetic symbionts (Symbiodiniaceae), leading to mass coral bleaching. Planktonic diazotrophs or dinitrogen (N2)-fixing prokaryotes are abundant in coral lagoon waters and could be an alternative nutrient source for corals ...
