| Abstract: | The process of oleandomycin inactivation in aqueous alkaline solutions with their heating was studied by using the microbiological method of the antibiotic content assay. The initial specific rate of inactivation of crystalline oleandomycin in buffer solutions and oleandomycin in the fermentation broth filtrate was evaluated. It was shown that the inactivation was retarded by the reaction products and the components of the fermentation broth filtrate. The production rate of oleandomycin anhydro derivatives amounting to 3-40 per cent of the total mass of the inactivation product was estimated by UV spectrophotometry. |
