โœฆ Synopsis

27 strains of mieroorgenisms including moulds, bacteria, aetinomyees and yeasts, which produced substances that flocculated a kaolin clay, were screened. One sU'ain, identified as Arthrobacter sp., secreted biofloeculant during growth. The flocculant ('MF-6) was purified to eleclrophoretic homogeneity by precipitation with ethanol and gel chromatography. Its molecular weight was higher than 10 e De_ It could efficiently flocculate all suspended solids tested in aqueous solution and colored water like dye solulJort, and its flocculating ability was significantly enhanced by adding Ca ~, Mn ~* , Mg ~, etc.

Graft copolymers of starch, amylose, and amylopectin with polyacrylamide have been synthesized using a ceric-ion-initiated solution polymerization technique. In the case of amylopectin-g-polyacrylamide ( Ap-g-PAM ) , four graft copolymers have been synthesized with variation in the number and length
