Abstract
Nitrogen-fixing cyanobacteria act as fertilizer plants providing nitrogenin situ for rice paddies. The filamentous heterocystous cyanobacteriaWestiellopsis iyengarii Jeeji Bai andMastigocladus laminosus Cohn are potential biofertilizers in the tropical region. Results presented in this paper show that combined nitrogen does not have any beneficial effect on the growth of bothWestiellopsis iyengarii andMastigocladus laminosus. While in the former this retardation in growth is seen in spite of an increase in pigmentation, proteins and photosynthesis, in the latter, the decrease in growth appears to be a direct consequence of the lowering in the cellular content of pigments and proteins.
