Isolation and application of a styrene-degrading strain of Pseudomonas putida to biofiltration.
A bacterial strain ST201 capable of degrading styrene was isolated from soil and identified as Pseudomonas putida. This strain had high tolerance to styrene and could degrade it completely in 48 h at concentrations up to 600 mg/l. P. putida ST201 was also demonstrated to degrade a mixture of benzene, toluene, ethylbenzene and p-xylene. A packed tower biofilter inoculated with P. putida ST201 was constructed which removed styrene vapor with a styrene elimination capacity of 90 g/m3.h.
