Complete Autotrophic Process for Nitrogen Removal from Ink- jet Printing Wastewater [PDF]
Lab-scale results on the treatability of ammonium-rich wastewater from textile digital printing highlight the feasibility of an innovative biological process, based on purely autotrophic bacterial populations: ammonium oxidising bacteria (AOB) and anaerobic ammonium oxidisers (AAO).

Microbial diversity, autotrophic- and heterotrophic processes in Mn-rich marine sediments
Marine microbial ecology aims to link microbial communities to the geochemical processes they drive. Molecular techniques have provided a view of the huge complexity of microbial communities and their metabolic potential, however, the information these ...

Mixotrophic flagellates, which have diverse nutritional modes and play important roles in connecting the microbial loop with the classical food chain, are ideal models to study the mechanisms of adaptation between different nutritional modes in protists.

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

Ecological and physiological studies on freshwater autotrophic picoplankton [PDF]
A series of studies were conducted to ascertain the importance of autotrophic picoplankton (0.2 - 2.0 fm in the longest dimension) in freshwaters. These included surveys of populations in lakes and rivers, and experiments on strains which had been ...

Measuring Isotope Fractionation by Autotrophic Microorganisms and Enzymes
Physical, chemical, and biological processes commonly discriminate among stable isotopes. Therefore, the stable isotope compositions of biomass, growth substrates, and products often carry the isotopic fingerprints of the processes that shape them ...

Clostridium aceticum was the first isolated autotrophic acetogen, converting CO2 plus H2 or syngas to acetate. Its genome has now been completely sequenced and consists of a 4.2-Mbp chromosome and a small circular plasmid of 5.7 kbp.

Phenylalanine <sup>15</sup>N enrichment likely indicates fungal-derived organic nutrient acquisition in mycoheterotrophic plants across fungal guilds. [PDF]
Summary Beyond fully mycoheterotrophic plants, many green plants may also obtain carbon from fungal partners. However, bulk stable isotope analyses often lack sufficient resolution in arbuscular mycorrhizal and rhizoctonia‐associated orchid systems, limiting inference of fungal‐derived organic nutrient acquisition.

A unique mechanism of catalytic bias regulated by diaphorase‐like subunit in formate dehydrogenase from Rhodobacter aestuarii is revealed. The diaphorase‐like subunit functions act as a biological “voltage rheostat” that controls the slow release of NADH to regulate redox balance, biasing the enzyme's catalytic preference toward CO2 reduction over ...
