Biodesulfurization was monitored in a recombinantPseudomonas putida CECT5279 strain. DszB desulfinase activity reached a sharp maximum at the early exponential phase, but it rapidly decreased at later growth phases. A model two-step resting-cell process combining sequentiallyP. putida cells from the late and early exponential growth phases was designed to significantly increase biodesulfurization.
