The stringent new regulations to lower sulfur content in fossil fuels require new economic
and efficient methods for desulfurization of recalcitrant organic sulfur. Hydrodesulfurization …

Sulfonates and sulfate esters are widespread in nature, and make up over 95% of the sulfur
content of most aerobic soils. Many microorganisms can use sulfonates and sulfate esters as …

This paper is a selective review on design approaches and associated catalysis and
chemistry for deep desulfurization and deep dearomatization (hydrogenation) of …

The actinomycete genus Rhodococcus is of interest for a variety of reasons. The metabolic
abilities of many species means that they can degrade a range of environmental pollutants …

The world focus on environmentally friendly fuels requires refiners to convert the
increasingly poor-quality crude oil into high-quality finished products. Refineries are facing …

Acyl‐CoA dehydrogenases constitute a family of flavoproteins that catalyze the α, β‐
dehydrogenation of fatty acid acyl‐CoA conjugates. While they differ widely in their …

The development of biocatalytic desulfurization of petroleum fractions may allow its use in
place of conventional hydrodesulfurization (HDS). Dibenzothiophene (DBT) is …

The field of Rhodococcus cell engineering is rapidly advancing because of the availability of
improved genetic tools and increased insights in their broad catabolic and biochemical …

We introduce a method of in vitro recombination or “DNA shuffling” to generate libraries of
evolved enzymes. The approach relies on the ordering, trimming, and joining of randomly …

A major concern among the environmental agencies includes the emission of sulfurous gas
into the environment. Consequently, the oil agencies are in constant search of alternative …
