A successful method to establish an inoculated bacterium in soil was developed. The bacterial strain used was Sphingomonas paucimobilis strain SS86, which has a unique ability to aerobically assimilate gamma-1,2,3,4,5,6-hexachlorocyclohexane (gamma-HCH). The bacterium has been known to disappear rapidly when simply inoculated into soils, whereas the gamma-HCH-assimilating S. paucimobilis indigenous to the soil where gamma-HCH has been annually applied survives and becomes established. However, strain SS86 was found to establish itself when introduced into a soil which had been exposed to gamma-HCH before bacterial inoculation, showing the same dynamics in the soil as shown by the indigenous gamma-HCH-assimilating S. paucimobilis. Use of a selective substrate was suggested to be a new method effective for establishing inoculated bacteria in soils.
