1. DETECÇÃO DE ESPÉCIES BACTERIANAS ENVOLVIDAS EM PROCESSOS DE BIODESSULFURIZAÇÃO EM UM SISTEMA DE LANDFARMING, NA REFINARIA GABRIEL PASSOS (REGAP), MINAS GERAIS.
The emission of sulfur from the burning of fossil fuels represents a global problem because it is the major cause of acid rain and air pollution. A major concern of the refineries is reducing the sulfur content of oil. The technology commonly used for this purpose is the hydrodesulfurization. An alternative that is being increasingly considered is biodesulfu

Crude oil and its distillates contain significant amounts of low-molecular-mass organosulphur compounds such as alkyland cycloalkyl thiols, alkyl- and arylthioethers and aromatic heterocycles based on thiophene. This last group of polycyclic aromatic sulfurated hydrocarbons includes thiophene itself, benzothiophene, dibenzothiophene, and their alkylated deri

3. Microbial Desulfurization of Alkylated Dibenzothiophenes from a Hydrodesulfurized Middle Distillate by Rhodococcus erythropolis I-19
Rhodococcus erythropolis I-19, containing multiple copies of key dsz genes, was used to desulfurize alkylated dibenzothiophenes (Cx-DBTs) found in a hydrodesulfurized middle-distillate petroleum (MD 1850). Initial desulfurization rates of dibenzothiophene (DBT) and MD 1850 by I-19 were 5.0 and 2.5 μmol g dry cell weight−1 min−1, more than 25-fold higher
