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.
采用抗生素含量测定的微生物学方法,研究了在加热条件下,竹桃霉素在碱性水溶液中的失活过程。评估了结晶竹桃霉素在缓冲溶液以及发酵液滤液中的竹桃霉素的初始失活比速率。结果表明,反应产物和发酵液滤液中的成分会抑制失活。通过紫外分光光度法估算了脱水竹桃霉素衍生物的生成速率,其占失活产物总质量的3% - 40%。
