ABSTRACT:
A multilayer structure is prepared containing immobilized nitrogen-fixing filamentous blue-green algal heterocyst cells. The cells are attached to a first layer which is a water-insoluble support having a surface energy of about 30 to about 115 dynes per cm. Second and third layers are adjacent and contiguous with first and second surfaces, respectively, of the first layer. At least one of the second and third layers is transparent to actinic radiation. The support may be cellulosic such as wood pulp. The immobilized cells fix nitrogen at a rate which is substantially greater than cells when not immobilized. The structure is useful as a nutrient source for agricultural purposes.
