Relationship between biodegradation rate and percentage of a compound that becomes sequestered in soil

摘要: A study was conducted to determine whether the rate of biodegradation phenanthrene determines extent its sequestration. Samples a single soil type with different biodegradative activities were used. Various rates obtained by use incubation temperatures, adding bacterial culture or both. Much compound became biologically unavailable (sequestered) when initial slow, and little remained if had high degradative activity. portion remaining in soils previously low activity degraded samples reinoculated incubated under favorable conditions, but significant amount still microbiologically unavailable. The data show that percentage will be sequestered form is determined soil.
