Boosting Dibenzothiophene Biodesulfurization Through Implantation of a Refactored DBT Pathway in a Tailored Pseudomonas putida Chassis [PDF]

Microbial Biotechnology
This study reports the efficacy of a rationally designed Pseudomonas putida strain to bring about the specific removal of S atoms from dibenzothiophene (DBT), the model heterocyclic sulfur‐containing component of raw petroleum.

Interplay between Sulfur Assimilation and Biodesulfurization Activity in Rhodococcus qingshengii IGTS8: Insights into a Regulatory Role of the Reverse Transsulfuration Pathway [PDF]

mBio, 2022
Biodesulfurization is a process that selectively removes sulfur from dibenzothiophene and its derivatives. Several natural biocatalysts harboring the highly conserved desulfurization operon dszABC, which is significantly repressed by methionine, cysteine,

Mitigating product inhibition in 2'-hydroxybiphenyl-2-sulfinate desulfinase (DszB) with synthetic glycosylation. [PDF]

Protein Sci
Abstract The combustion of sulfur‐rich crude oil is toxic to the environment, making the removal of sulfur impurities a priority for the sustainable use of liquid fuels. Biodesulfurization via the 4S pathway is a promising approach due to its C‐S bond cleavage specificity and mild operating conditions.

The Arsenal of Aromatic Degrading Bacteria: How They Sense, Chase, Adapt and Destroy Environmental Pollutants. [PDF]

Microb Biotechnol
In the environment, bacteria sense aromatic pollutants, migrate toward them, adapt to toxicity, and deploy specialized uptake and catabolic systems. Genomic plasticity, metabolic versatility and division of labor within populations together aid in the degradation of persistent aromatics, highlights that biodegradation is driven by various eco ...

Investigating role of abiotic side and finding optimum abiotic condition for improving gas biodesulfurization using Thioalkalivibrio versutus [PDF]

Scientific Reports, 2022
Hydrogen sulfide (H2S) is a super toxic substance that produces SOx gases when combusted. Therefore, it should be removed from gas streams. Biodesulfurization is one of the developing methods for removing sulfide.
