Heterotrophy and Nitrogen Fixation in Chlorogloea fritschii [PDF]

Journal of General Microbiology, 1965
The blue-green alga Chlorogloea fritschii fixed elementary nitrogen to a limited extent in the dark in a strictly inorganic medium. Growth and nitrogen fixation continued in the dark when a suitable organic substrate was present in the medium. Among the organic substrates tested, sucrose (0.01 M) was the most readily utilized and was outstanding in ...

Oxygen and Heterotrophy Affect Calcification of the Scleractinian Coral Galaxea fascicularis

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

Light May Have Triggered a Period of Net Heterotrophy in Lake Superior

, 2018
Recent studies of Lake Superior, the Earth\u27s largest freshwater lake by surface area, describe it as net heterotrophic (primary production \u3c community respiration), making it a net source of carbon dioxide (CO2) to the atmosphere.

Organic Carbon and Nitrogen Isoscapes of Reef Corals and Algal Symbionts: Relative Influences of Environmental Gradients and Heterotrophy

, 2020
The elemental (C/N) and stable isotopic (δ13C, δ15N) compositions and compound-specific δ15N values of amino acids (δ15NAA) were evaluated for coral holobionts as diagnostic tools to detect spatiotemporal environmental ...

Heterotrophy in recruits of the scleractinian coral Pocillopora damicornis

, 2013
Heterotrophy is essential for meeting the metabolic requirements of scleractinian corals but the feeding mechanisms of coral juveniles are poorly understood.

No short-term effect of sinking microplastics on heterotrophy or sediment clearing in the tropical coral Stylophora pistillata

, 2022
Investigations of encounters between corals and microplastics have, to date, used particle concentrations that are several orders of magnitude above environmentally relevant levels.

Suppression subtractive hybridization reveals transcript profiling of Chlorella under heterotrophy to photoautotrophy transition.

, 2012
Microalgae have been extensively investigated and exploited because of their competitive nutritive bioproducts and biofuel production ability. Chlorella are green algae that can grow well heterotrophically and photoautotrophically.

Co-variation between autotrophy and heterotrophy in the Mediterranean coral Cladocora caespitosa [PDF]

, 2010
This study quantifies the relative contributions of autotrophy and heterotrophy to the energy budget of the temperate scleractinian species Cladocora caespitosa Linnaeus 1767. Colonies were incubated under different light and feeding regimes, and changes

Fatty acid composition of three Chlorella strains during auto– and heterotrophy.

, 2014
The distribution of total fatty acids measured as FAME and TAG are plotted as solid and diagonal bars, respectively, for C. protothecoides UTEX 411, C. vulgaris UTEX 265, and C. sorokiniana UTEX 1230.
