DBT degradation enhancement by decorating Rhodococcus erythropolis IGST8 with magnetic Fe3O4 nanoparticles [PDF]

, 2009
Biodesulfurization (BDS) of dibenzothiophene (DBT) was carried out by Rhodococcus erythropolis IGST8 decorated with magnetic Fe3O4 nanoparticles, synthesized in-house by a chemical method, with an average size of 45-50 nm, in order to facilitate the post-

Visualizing the invisible: class excursions to ignite children’s enthusiasm for microbes

Microbial Biotechnology, Volume 13, Issue 4, Page 844-887, July 2020., 2020
The ubiquity of microbes, their manifold activities and pervasive influence on the health of all life, local environments and the planet, necessitate an understanding of relevant microbial processes for informed, evidence‐based decision‐making at all levels of society – i.e. Microbiology Literacy.

Adsorptive Desulfurization of Organic Sulfur from Model Fuels by Active Carbon Supported Mn (II): Equilibrium, Kinetics, and Thermodynamics

International Journal of Chemical Engineering, Volume 2020, Issue 1, 2020., 2020
Mn (II)/AC adsorbents were prepared by ultrasonic impregnation. The 2 wt. % Mn/AC showed best adsorptive performance, and the optimal adsorption temperature was 313 K. Benzene, methylbenzene, and naphthalene were used to explore the adsorptive selectivity of Mn/AC, indicating that Mn could enhance the adsorptive capacity but could not improve the ...

Assessment of the Oxidative Desulfurization of Middle Distillate Surrogate Fuels with Spectroscopic Techniques

Journal of Analytical Methods in Chemistry, Volume 2020, Issue 1, 2020., 2020
The oxidative desulfurization of five (5) model sulfur compounds and eleven (11) surrogate blends was investigated using the hydrogen peroxide (H2O2)‐acetic acid (CH3COOH) system. Consequently, extractive desulfurization was carried out using conventional solvents.

Bacterial Biological Factories Intended for the Desulfurization of Petroleum Products in Refineries

Fermentation, 2023
The removal of sulfur by deep hydrodesulfurization is expensive and environmentally unfriendly. Additionally, sulfur is not separated completely from heterocyclic poly-aromatic compounds. In nature, several microorganisms (Rhodococcus erythropolis IGTS8,

Designing recombinant Pseudomonas strains to enhance biodesulfurization [PDF]

Journal of Bacteriology, 1997
The dsz biodesulfurization cluster from Rhodococcus erythropolis IGTS8 has been engineered under the control of heterologous broad-host-range regulatory signals to alleviate the mechanism of sulfur repression, and it was stably inserted into the chromosomes of different Pseudomonas strains.

Exploring the Mechanism of Biocatalyst Inhibition in Microbial Desulfurization [PDF]

, 2013
Microbial desulfurization, or biodesulfurization (BDS), of fuels is a promising technology because it can desulfurize compounds that are recalcitrant to the current standard technology in the oil industry. One of the obstacles to the commercialization of

Biodesulfurization in Biphasic Systems Containing Organic Solvents [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT Biphasic systems can overcome the problem of low productivity in conventional media and have been exploited for biocatalysis. Solvent-tolerant microorganisms are useful in biotransformation with whole cells in biphasic reactions.
