	bibo:abstract "The direct utilization by higher plants of nitrogen fixed\nby blue-green algae could play a substantial part in the\nEarth's nitrogen cycle. That certain species of blue-green\nalgae can fix nitrogen when grown in solution culture is\nwell established. The maintenance of soil nitrogen\nsupplies in rice paddy has been attributed to the growth\nand fixation of nitrogen by blue-green algae. Recently it\nwas postulated that the blue-green algae may be important\nin the nitrogen economy of grazing lands."^^xsd:string;
