The sorption of N-(β-ketokaproil)-L-homoserine lactone (CAS 143537-62-6) on activated carbon (CAS 16291-96-6) was studied using the recombinant Escherichia coli JLD271, pAL103; luxR + luxI_luxCDABE luminescent biosensor. The sorption process was completed in 60 min, relatively stable over a wide range of pH values, characterized by the sorption capacity 9×10−9 mg / mg and most correctly described by the Langmuir theory for a homogeneous monomolecular surface adsorption. The result explained the use of activated carbon for bacterial infections treatment which uses acylated homoserine lactones mediated system in cell-to-cell chemical communication.
