| Abstract: | Streptomyces shandongensissp.nov,a broad antibiotic spectrum strain, was isolated from the soil in the screening of agriculture antagonistic strains. The effects of heat, pH and UV on the stability of the bioactive substance in the fermented broth were studied. The water solubility and ion character of the antibiotics were analysized by pH paper chromatography and thin-layer chromatography. The results showed that the weakly acidic antibiotics were stable to heat, pH and UV, and can be dissolved in water and organic solvent. The studies provide valuable information for the further purification and structure determination. |
