On cultivation of the alga Vaucheria dichotoma (Xanthophyceae) in axenic culture

Phycologia, 1976
Abstract The alga Vaucheria dichotoma was isolated and cultivated under axenic conditions. Optima of various parameters were determined: temperature 22–23 °C, pH 8.0–8.5, salinity around 1%. As a P-source, α- or β-glycerophosphate was as good as inorganic phosphate; good growth was obtained within a wide range of concentrations of all three P-compounds.

Osmotic adjustments in a psychrophilic alga, Xanthonema sp. (Xanthophyceae)

Environmental and Experimental Botany, 2008
Abstract Extremophile microalgae show a remarkable ability to cope with harsh environments, yet still relatively little is known about the molecular basis for such tolerance. In this work the susceptibility of a psychrophylic alga isolated from alpine snowbanks, Xanthonema sp., to either water or salt stress conditions was assessed, and mechanisms ...

???????? ?????????? Botrydium Wallroth ?? Vaucheria De Candolle (Xanthophyceae) ?????? ?????????????????????? (????????????)

2019
The yellow green algae belonging to the genera Botrydium and Vaucheria (Xanthophyceae) were studied in the south of the Baikal region from 2011 to 2017. As a result, 375 populations of 15 siphonous xanthophytes from Botrydium (1 species) and Vaucheria (13 species and 1 variety) have been revealed in the 218 localities of the studied region.

Zum Feinbau von Botrydium granulatum Grev. (Xanthophyceae)

Archiv f�r Mikrobiologie, 1967
Die polyenergide Xanthophycee Botrydium granulatum wurde nach Glutaraldehydfixierung elektronenmikroskopisch an Ultradunnschnitten untersucht. 1. Die Energiden sind cytomorphologisch nicht gegeneinander abgegrenzt. 2. Die Chromatophoren besitzen keine Grana, ihre Thylakoide sind zu Dreiergruppen assoziiert.

[Antheraxanthin-zeaxanthin conversion in Vaucheria sessilis (Xanthophyceae)].

Planta, 2014
There is a light-induced transformation of antheraxanthin to zeaxanthin in the heterokont alga Vaucheria. This reaction can be reversed in the dark. The other carotenoids remain unchanged under the influence of light.
