The bacterium Sphingomonas sp. strain SS33, obtained from parent diphenyl ether-mineralizing strain SS3 (S. Schmidt, R.-M. Wittich, D. Erdmann, H. Wilkes, W. Francke, and P. Fortnagel, Appl. Environ. Microbiol. 58:2744-2750, 1992) after several weeks of adaptation on 4,4'-difluorodiphenyl ether as the new target compound, also utilized 4,4'-dichlorodiphenyl ether for growth. Intermediary halocatechols were also mineralized via the ortho pathway by type I enzymes. 4,4'-Dibromodiphenyl ether was not used as a carbon source although transformation by resting cells yielded mononuclear haloaromatic compounds, such as 4-bromophenol and 4-bromocatechol. The same was true for the conversion of 2,4-dichlorodiphenyl ether, which yielded the respective (halo-) phenols and (halo-) catechols.
从亲本二苯醚矿化菌株SS3（S. Schmidt、R.-M. Wittich、D. Erdmann、H. Wilkes、W. Francke和P. Fortnagel，《应用与环境微生物学》58:2744 - 2750，1992年）经数周在4,4'-二氟二苯醚作为新目标化合物上适应后获得的鞘氨醇单胞菌属菌株SS33，也利用4,4'-二氯二苯醚进行生长。中间卤代邻苯二酚也通过I型酶经由邻位途径矿化。4,4'-二溴二苯醚虽未用作碳源，但静息细胞转化产生了单核卤代芳烃化合物，如4-溴苯酚和4-溴邻苯二酚。2,4-二氯二苯醚的转化情况也是如此，其产生了相应的（卤代）酚和（卤代）邻苯二酚。
