Solubilization of coal by an extracellular product fromStreptomyces setonii 75Vi2

Abstract

Several low-ranked coals were solubilized when placed on the surface of agar cultures ofStreptomyces viridosporous T7A andS. setonii 75Vi2. When grown in submerged cultureS. setonii 75Vi2 produced an extracellular component that was capable of solubilizing coals. The extracellular coal solubilizing component had a molecular weight of S. setonii 75Vi2 is nonenzymatic.
