Growth and fatty acid profiles of microalgae species isolated from the Baja California Peninsula, México
The growth rate, fatty acid profile and toxicity of 21 microalgae strains (Cyanophyceae (3), Chlorodendrophyceae (1), Xanthophyceae (1) and Bacillariophyceae (16)), isolated from coastal waters of Baja California (NW México), were determined. Cyanophytes Komvophoron sp. had the highest growth rates...
