Analysis of dibenzothiophene desulfurization in a recombinant Pseudomonas putida strain.

摘要

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