The biocatalysis of substrates in the gas phase may offer advantages o
ver many conventional solution-based reactions, both in analytical dev
ices and in bioreactors designed to accommodate this new technology. T
o date, however, the range of substrates for which gas-phase biocataly
sis has been shown to be suitable is limited. Further research is requ
ired to establish the parameters that affect the kinetics and producti
vity of such systems.
