PROCESS FOR PRODUCING IMMOBILIZED MICROORGANISM- COMPLEX HAVING CONTROLLING ACTIVITY AGAINST PLANT PATHOGENIC MICROORGANISM

摘要

The culture medium of the microorganisms antagonistic to plant pathogenic microorganisms are treated with an inorganic salt of a metal having a valency of 2 or more so as to give their cell walls positive charges, mixed with 5-10 w/w% of ?-, .epsilon.- or .lambda.-carrageenan, and then spray-dried. This successive process allows the microorganism to be immobilized. The produced microorganism -complex has abilities to control plant pathogenic microorganisms and to preserve the immobilized microorganisms for a long period.
