A test of the ash-free dry weight technique on the developmental stages of Patiriella spp. (Echinodermata : Asteroidea) [PDF]

, 2001
Determination of the ash-free dry weight (AFDW) of marine specimens requires samples to be rinsed, soaked, and centrifuged. Problems associated with this technique were examined with the developmental stages of seastar species (Patiriella) with different

The role of mixotrophic protists in the biological carbon pump [PDF]

, 2014
The traditional view of the planktonic food web describes consumption of inorganic nutrients by photoautotrophic phytoplankton, which in turn supports zooplankton and ultimately higher trophic levels.

Chloroplast symbiosis in a marine ciliate: ecophysiology and the risks and rewards of hosting foreign organelles

Frontiers in Microbiology, 2012
Simultaneous use of both heterotrophic and autotrophic metabolism (mixotrophy) is common among protists. Strombidium rassoulzadegani is a planktonic mixotrophic marine ciliate that saves chloroplasts from its algal food and obtains a nutritional subsidy

An autumn biodiversity survey on heterotrophic and mixotrophic protists along a coast-to-offshore transect in the Gulf of Naples (Italy)

Advances in Oceanography and Limnology, 2021
Plankton communities include both unicellular and multicellular organisms. An important unicellular component is represented by those protists (i.e., unicellular eukaryotes) that consume bacteria, other protists, and even small animals.

Estuarine Nitrifiers: New Players, Patterns and Processes [PDF]

, 2010
Ever since the first descriptions of ammonia-oxidizing Bacteria by Winogradsky in the late 1800s, the metabolic capability of aerobic ammonia oxidation has been restricted to a phylogenetically narrow group of bacteria.

Mixotrophy in cyanobacteria

Current Opinion in Microbiology
Cyanobacteria evolved the oxygenic photosynthesis to generate organic matter from CO2 and sunlight, and they were responsible for the production of oxygen in the Earth's atmosphere. This made them a model for photosynthetic organisms, since they are easier to study than higher plants.

Isolation of an Obligate Mixotrophic Methanogen That Represents the Major Population in Thermophilic Fixed-Bed Anaerobic Digesters

Microorganisms, 2020
Methanothermobacter Met2 is a metagenome-assembled genome (MAG) that encodes a putative mixotrophic methanogen constituting the major populations in thermophilic fixed-bed anaerobic digesters.

Mixotrophy in a Local Strain of Nannochloropsis granulata for Renewable High-Value Biomass Production on the West Coast of Sweden

Marine Drugs, 2022
A local strain of Nannochloropsis granulata (Ng) has been reported as the most productive microalgal strain in terms of both biomass yield and lipid content when cultivated in photobioreactors that simulate the light and temperature conditions during the

Why mixotrophy flourished in water but rarely on land

Frontiers in Ecology and Evolution
Mixotrophy, the ability to combine photosynthesis with heterotrophic acquisition of carbon or nutrients, is now recognized as a central feature of aquatic microbial food webs and a recurrent strategy in several protist and simple animal lineages.
