Experimental evaluation of a diffusion reaction model (part 1) for the determination of both steady-and transient-state behavior of biofilters for waste air biotreatment is presented. The model, applied to the aerobic biodegradation of methyl ethyl ketone (MEK) and methyl isobutyl ketone (MIBK) vapors from air as single and as mixed pollutants, proved appropriate for describing most of the expe...

Here, we present the complete genome of Rhodococcus pyridinivorans SB3094, a methyl-ethyl-ketone (MEK)-degrading strain used for bioaugmentation relating to the treatment of wastewater contamination with petrochemical hydrocarbons. The genome highlights important features for bioaugmentation, including the genes involved in the degradation of MEK.

Methyl ethyl ketone (MEK) enters the atmosphere following direct emission from vegetation and anthropogenic activities, as well as being produced by the gas-phase oxidation of volatile organic compounds (VOCs) such as nbutane. This study presents the first overview of ambient MEK measurements at six different locations, characteristic of forested, urban and marine environments. In order to unde...

Background: Candida albicans is the most prevalent fungi isolated in endodontic infections. In this study, ability of C. biofilm to tolerate novel solvent mixtures methyl ethyl ketone (MEK)/tetrachloroethylene (TCE) and MEK/orange oil (OOil) sequentially standard irrigation sodium hypochlorite (NaOCl) ethylenediaminetetraacetic (EDTA) was evaluated. Methods: Biofilm cell cultures SC 5314 were t...

Methyl Ethyl Ketone and Methyl Isobutyl Ketone Not Carcinogenic The April 22, 1993, issue of Environmental Health Perspectives contained a commentary by Legator and Strawn entitled "Public Health Policies Regarding Hazardous Waste Sites and Cigarette Smoking: An Argument by Analogy." Although the article does not include any discussion of either methyl ethyl ketone (MEK) or methyl isobutyl keto...

An novel diffusion reaction model for the determination of both the steady-state and transient-state behavior of biofilters for waste air biotreatment is developed and discussed. The model considers the reactor to comprise finite sections, for each of which transient mass balances are established and solved by digital simulation. The elimination of methyl ethyl ketone (MEK) and methyl isobutyl ...

Levulinic acid (LA), 4-oxo-pentanoic acid, is a new platform chemical with various potential uses. In this paper, catalytic hydrogenation and oxidation of levulinic acid were studied. It was shown from experiments that levulinic acid can be hydrogenated to γ-valerolactone (GVL) over transition metal catalysts and oxidative-decarboxylated to 2-butanone (methyl-ethyl-ketone, MEK) and methyl-vinyl...
