从甘蔗根际土壤中分离到的假单胞菌在好氧条件下不仅能代谢六六六的α和伽马异构体，而且能代谢热力学上更稳定的β异构体。细菌对这三种异构体的降解导致暂时性代谢物的积累，并最终释放化学计量比的共价键合氯作为氯化物。
A Pseudomonas sp., isolated from sugarcane rhizosphere soil, readily metabolized not only alpha and gamma isomers of hexachlorocyclohexane, but also the thermodynamically more stable beta isomer, under aerobic conditions. Bacterial degradation of the three isomers led to the accumulation of a transitory metabolite and eventual release of covalently linked chlorine as chloride in stoichiometric amounts.
