The dark ocean and the underlying deep seafloor together represent the largest
environment on this planet, comprising about 80% of the oceanic volume and covering more …

Heterotrophic protists (unicellular eukaryotes) form a major link from bacteria and algae to
higher trophic levels in the sunlit ocean. Their role on the deep seafloor, however, is only …

Marine heterotrophic flagellates (HFs) form a diverse and ecologically relevant functional
group of bacterial grazers and nutrient remineralizers in oceanic waters. Despite playing a …

The benthic biome of the deep‐sea floor, one of the largest biomes on Earth, is dominated
by diverse and highly productive heterotrophic protists, second only to prokaryotes in terms …

Deep-sea ecosystems, limited by their inability to use primary production as a source of
carbon, rely on other sources to maintain life. Sedimentation of organic carbon into the deep …

Cafeteria is one of the most common and ecologically significant genera of heterotrophic
nanoflagellates in marine plankton. We could isolate and cultivate 29 strains …

The heterotrophic nanoflagellate genus Cafeteria has been found to be ubiquitously
distributed in the marine realm. We could isolate and cultivate ten strains morphologically …

The nitrite-dependent anaerobic methane oxidation (n-damo) process is believed to have
good application prospects, but its development is limited by the low growth rate and low …

A new Euplotes species, isolated from abyssal depths (> 4000 m) of the North Atlantic
Ocean, was described based on morphology, ciliary pattern and molecular data. Euplotes …

Diversity of microbial eukaryotes is estimated largely based on sequencing analysis of the
hypervariable regions of 18S rRNA genes. But the use of different regions of 18S rRNA …
