Chromulina placentulasp. nov. (Chrysophyceae), a freshwater nannoplankton flagellate

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...

Algoriphagus aquatilis sp. nov., isolated from a freshwater lake.

A Gram-negative, non-spore-forming, non-motile bacterium, strain A8-7(T), was isolated from fresh water of a slightly alkaline lake, Longhu Lake, in Daqing, north-east China, and its taxonomic position was studied by using a polyphasic approach. Strain A8-7(T) was aerobic, heterotrophic and positive for catalase and oxidase. It grew at 20-37 degrees C (optimum 30 degrees C) and pH 5.5-10.5 (opt...

Gemmobacter lanyuensis sp. nov., isolated from a freshwater spring.

A bacterial strain designated Orc-4(T) was isolated from a freshwater spring in Taiwan and characterized using the polyphasic taxonomic approach. Cells of strain Orc-4(T) were facultatively anaerobic, Gram-reaction-negative, poly-β-hydroxybutyrate-accumulating, non-motile rods surrounded by a thick capsule and forming cream-white colonies. Growth occurred at 15-40 °C (optimum, 25-30 °C), at pH ...

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....
