These microorganisms have been reported to provide DEHP, which may be produced by these microorganisms. The 14C contents (pMC) of DEHP and a positive control (a mixture of two fatty acids) purified from the ethanol extract of the dinoflagellate cells were 16.3 \u571f 0.1 and 85.7 \u571f 0.3, respectively, and DEHP and a mixture of two unsaturated fatty acids from the broth filtrate of S. bangladeshensis were 14.3 \u58eb 0.1 and 101.9 \u58eb 0.4, respectively. Consequently, the origin of DEHP isolated from these microorganisms was an industrial product. There were several reports that claimed DEHP was a microbial origin by the fermentation with radio active and stable isotope-labeled biosynthetic precursors. However, a labeled DEHP was not isolated but detected by HPLC or MS in these reports. Our study suggests at a labeled DEHP has to be purified and examined incorporated pattern to prove its origin.\u653e\u7dda\u83ccStreptomyces bangladeshensis NBRC
