Abstract
Four green microalgae (Chlorella sorokiniana, Chlorella vulgaris, Scenedesmus obliquus and Selenastrum capricornutum), a wild Bolivian microalga strain and two cyanobacteria (Anabaena catenula and Microcystis aeruginosa) were compared for tolerance to salicylate, O2 production capacity and ability to support salicylate degradation by a Ralstonia basilensis strain in symbiotic microcosms with the microalgae. Microcystis aeruginosa had the highest tolerance to salicylate at 500 mg l-1 and 1500 mg l-1 but only produced 0.7 mg O2 l-1 h-1 in the absence of pollutant. Chlorella sorokiniana resisted salicylate at 1500 mg l-1 with the highest O2 production in the absence of salicylate (26 mg l-1 h-1) closely followed by the Bolivian microalga (23... (More)

Selenastrum capricornutum and Anabaena catenula were completely inhibited by salicylate at 500 mg l-1. When inoculated with Ralstonia sp. and supplied with salicylate, Chlorella sorokiniana had the highest removal rate (19 mg l-1 h-1), followed by the wild Bolivian strain (18 mg l-1 h-1) and Chlorella vulgaris (14 mg l-1 h-1).
