The culture pure Pseudomonas sp. CPE1 strain capable of metabolizing low-chlorinated biphenyls in the presence of biphenyl was found to be able to grow on Aroclor 1221 in the absence of an additional carbon source. The presence of glass beads (diameter = 3 mm, 30% w/v) or Triton X-100 (0.066% v/v) in the culture medium significantly enhanced the aerobic dechlorination of the polychlorinated biphenyls present in Aroclor 1221 in batch cultures of CPE1 strain. This result has been ascribed to an increase of Aroclor 1221 bioavailability in the cultures containing glass beads or Triton X-100, probably deriving from a greater interface area PCB-water, i.e. the surface area on which the polychlorobiphenyl degradation seems to take place.
在联苯存在的情况下，能够代谢低氯代联苯的纯培养假单胞菌CPE1菌株被发现能够在没有额外碳源的情况下以Aroclor 1221为培养基生长。在CPE1菌株的分批培养中，培养基中玻璃珠（直径 = 3 mm，30% w/v）或Triton X-100（0.066% v/v）的存在显著增强了Aroclor 1221中多氯联苯的好氧脱氯作用。这一结果归因于在含有玻璃珠或Triton X-100的培养物中Aroclor 1221生物可利用性的增加，这可能源于更大的多氯联苯 - 水界面面积，即多氯联苯降解似乎发生的表面积。
