Biodesulfurization

Part of speech: noun

Definitions

1. A process that uses biological agents such as bacteria or enzymes to remove sulfur compounds from fuels or materials, thereby reducing sulfur emissions and environmental pollution
2. The application of microorganisms or biological catalysts to extract sulfur from fossil fuels or substances, helping to decrease the release of sulfur oxides during combustion
3. Utilizing living organisms or their enzymatic activity to eliminate sulfur-containing elements from fuels or raw materials, aiming to minimize sulfur pollution and improve fuel quality

Etymology: Biodesulfurization is a plain technical coinage, built by joining the prefix "bio-", meaning life or biological, to "desulfurization", the removal of sulfur. The "de-" prefix marks removal, "sulfur" is the element itself, and "-ization" turns the process into a noun. Put together, the word names the use of living organisms, typically certain bacteria, to strip sulfur from compounds such as those in crude oil or coal. The point of the term is contrast with conventional methods. Industrial desulfurization usually relies on high temperature, pressure and hydrogen gas, a process called hydrodesulfurization. Biodesulfurization instead works at ambient conditions, with microbes that cut sulfur out of molecules while leaving the rest of the fuel intact.

Synonyms: biological desulfurization, bio-desulfurization
