Spiniferomonas triangularissp. nov., a new silica-scaled freshwater flagellate (Chrysophyceae, Paraphysomonadaceae)

Observations On The Ultrastructure Of The Naked Freshwater Flagellate Chrysochromulina tobin sp. nov. (Haptophyta)

Haptophytes are nano-planktonic unicells whose small size belies their contribution of 30-50% of the total photosynthetic stock in the world's ocean [1]. In addition to their major role in contributing to the Earth's carbon cycle [1], blooms of these algae can produce noxious odors that compromise water quality and can generate toxins responsible for fish and animal mortality [2]. Because the f...

Biodiversity and biogeographical implications of silica-scaled chrysophytes (Chrysophyceae and Synurophyceae) of the northeast wetlands of Argentina

Wetlands and water bodies in the Parana Delta River and Ibera System of northeast Argentina were studied for scaled chrysophytes. The Delta region of the Parana River is composed of a series of braided channels, streams and lagoons that extend over 17,500km2. Although the Delta is situated in the temperate zone, it experiences a more subtropical climate. The water ways of the Ibera System consi...

Inhella inkyongensis gen. nov., sp. nov., a new freshwater bacterium in the order Burkholderiales.

A freshwater bacterium, designated IMCC1713(T), was isolated from a highly eutrophic artificial pond. Cells of the strain were Gram-negative, chemoheterotrophic, polybeat and obligately aerobic short rods that were motile with a single polar flagellum. The 16S rRNA gene sequence similarity analysis showed that the novel strain was most closely related to the species Roseateles depolymerans (96....

Inhella inkyongensis gen . nov . , sp . nov . , a New Freshwater Bacterium in the Order

The Morphology, Ultrastructure and SSU rRNA Gene Sequence of a New Freshwater Flagellate, Neobodo borokensis n. sp. (Kinetoplastea, Excavata).

A small free-living freshwater bacteriotrophic flagellate Neobodo borokensis n. sp. was investigated by electron microscopy and analysis of its SSU ribosomal RNA gene. This protist has paraxonemal rods of typical bodonid structure in the flagella, mastigonemes on the proximal part of the posterior flagellum, two nearly parallel basal bodies, a compact kinetoplast, and discoid mitochondrial cris...
