Raphidocelis subcapitata

Trifluoroacetic acid has been shown to impact sensitive species of algae, such as Raphidocelis subcapitata, with a lowest observed effective dose of 360 xg/l [236]. Most plant species tested were impacted by trifluoroacetic acid at concentrations in the mg/1 range [236,240]. Although these toxic concentrations are 2 - 3 orders of magnitude higher than typical current environmental levels [237-239], there is concern that trifluoroacetic acid may accumulate over many years in terminal water bodies to the point that concentrations toxic to algae and some higher plants may be achieved.

This alga, S. capricornutum (Printz), has undergone two recent taxonomical changes. It was first renamed Raphidocelis subcapitata and later became Pseudokirchneriella subcapitata. Following these taxonomical tribulations, the correct appellation is purported to be Pseudokirchneriella subcapitata (Korshikov) Hindak (for explanations see Chapter 3, volume 1 of this book). ...

The most commonly used species of freshwater algae are Raphidocelis subcapitata (former Selenastrum capricornutum), Desmodesmus armatus (former Scenedesmus subspicatus) and Chlorella sp., and the marine algae Skeletonema costatum and Phaeodactylum tricornutum. They are well known for their physiological properties and sensitivity to a couple of toxic elements and organic substances. Their optimal growth conditions are known as well as their reproduction rate, which is a validity criterion for the standardised tests.
