In conclusion, the efficient beta-CP-degrading strain CH7, isolated
from activated sludge and identified as P. aeruginosa, could
isomerize beta-CP to CP, utilize it as the sole carbon and energy
source for BS production, and degrade the toxic contaminant. Under
optimum conditions, 67% of total beta-CP could be degraded
after four days of cultivation in MSM supplemented with
100 mg L1 beta-CP. Our results clarify that P. aeruginosa strain
CH7 with BS production has good potential for the detoxification
and bioremediation of environments contaminated by beta-CP.
