Abstract
A process is provided for treating spent antibiotic fermentation broth containing concentrations of up to about 12 percent fats and up to about 9.5 percent proteins which comprises acidifying such spent broth to coagulate the fats, impinging the coagulated fat on a coalescing strainer, basifying the effluent therefrom to coagulate the proteinaceous material, filtering the basified spent broth to remove the proteinaceous material, and passing the filtrate serially through anionic and cationic exchange resins, wherein the biological oxygen demand of the effluent therefrom is reduced to a level of less than 0.04 g. oxygen per liter.
