Soils that had a high binding capacity for inorganic orthophosphate (Pi) had reduced capacities to bind ionic alkyl phosphorus compounds. Only ionic methylphosphonate (MPn) and ionic phenylphosphonate exhibited moderate binding. Pseudomonas testosteroni used either MPn or Pi as a sole phosphorus source and exhibited diauxic utilization of MPn and Pi. The utilization of MPn was suppressed in the presence of Pi. This suppression was abolished by a Pi-binding soil. The soil did not have a significant effect on the maximum rate of degradation of either MPn or the poorly bound ionic O-isopropyl methylphosphonate, whereas the amount of MPn (but not the amount of O-isopropyl methylphosphonate) metabolized was reduced in the presence of soil
对无机正磷酸盐（Pi）具有高结合能力的土壤，其结合离子烷基磷化合物的能力降低。只有离子型甲基膦酸盐（MPn）和离子型苯基膦酸盐表现出适度的结合。睾丸酮假单胞菌将MPn或Pi用作唯一的磷源，并表现出对MPn和Pi的二次生长利用。在Pi存在的情况下，MPn的利用受到抑制。这种抑制作用被一种结合Pi的土壤消除。该土壤对MPn或结合性差的离子型O-异丙基甲基膦酸盐的最大降解速率没有显著影响，而在有土壤存在的情况下，代谢的MPn量（但不是O-异丙基甲基膦酸盐的量）减少了。
