Abstract
A constant CO2 equilibrium level was reached with marine algae in a closed container in sunlight in sea water. With an air atomosphere, values of 5 mg CO2 per litre were maintained by Boodlea composita and by Halimeda cylindracea, and 2 mg per litre by Enteromorpha sp. These equilibrium values were increased in an atmosphere of 100% oxygen. These values may be comparable with compensation point analyses for land plants and are indicative of photorespiration in marine algae.Keywords
