In-Depth Information
Distribution: Europe, Southeast Asia
Habitat: Freshwater systems
Description: The cells of this species are spherical or subspherical with cup-
shaped chloroplast and one pyrenoid. Bilagellated zoospores are produced
by this species.
Compounds and activities: Bioactive phenolic acid compounds (protocatechuic,
p-hydroxybenzoic, 2,3-dihydroxybenzoic, chlorogenic, vanillic, caffeic,
p-coumaric, and salicylic acids), cinnamic acid, and hydroxybenzaldehydes
(p-hydroxybenzaldehyde, 3,4-dihydroxybenzaldehyde, and vanillin) pos-
sessing antioxidative and anticancer properties have been isolated from this
species (Onofrejova et al.,
2010).
