ABSTRACT:
J-1 which is a strain of cyanobacteria is used to form and excrete a material useful as a floculating agent and as an additive useful in soil conditioning.
Method of separating and culturing the cyanobacteria under conditions necessary to achieve maximum formation and excretion of the material into solution.
Method of purifying and separating excreted as well as intracellular material from cyanobacteria.
Method of clarifying a particulate-laden liquid with a material excreted by cyanobacteria, and particularly species J-1.
Extracellular polymeric material which is water-soluble, non-dialyzable, having a molecular weight greater than 100,000 based on Sephadex column elution G 150, containing sugar, peptide, and fatty acid moieties, giving a positive Anthrone test, having an absorption peak of 205 nm. using a Perkin-Elmer spectrophotometer Model 402.
