Effects of petroleum hydrocarbons on the growth of a microalga, Isochrysis sp. (Chrysophyta)
MetadataShow full item record
Effects of water soluble fraction of Bombay High crude oil and heavy duty marine diesel on the growth of a microalga were examined and compared. Most concentrations of the oil depressed the growth rate in Isochrysis sp. Marine diesel prevented the growth of the alga in a concentration above 10%, while crude oil at a similar concentration had little effect on the growth. Hydrocarbon would cause environmental damage through selective effects on natural biota in the marine environment.
