Abstract
Intracellular substances of microbial origin are prepared by culturing a microorganism in a suitable nutrient medium therefor in the presence of at least one antibiotic in sufficient amount to weaken the walls of the microorganism cells but insufficient to arrest growth of the microorganism and induce discharge of the intracellular substances into the culture medium, thereafter rupturing the walls of at least a part of the microorganism cells and recovering the intracellular substances released by rupture of the cell walls.
