Evaluating the Effect of Lignocellulose-Derived Microbial Inhibitors on the Growth and Lactic Acid Production by Bacillus coagulans Azu-10

Fermentation, 2021
Effective lactic acid (LA) production from lignocellulosic biomass materials is challenged by several limitations related to pentose sugar utilization, inhibitory compounds, and/or fermentation conditions.

Influence of Hydrothermal Carbonization on Composition, Formation and Elimination of Biphenyls, Dioxins and Furans in Sewage Sludge

Energies, 2018
In many areas of application, the influence of hydrothermal carbonization (HTC) on the composition of organic pollutants is still unexplored. In this study, sewage sludge (SS) was carbonized and the input as well as the hydrochar were examined for the ...

Dioxins and furans in fly ashes from an incinerator

Revista Facultad de Ingeniería Universidad de Antioquia, 2004
The amount of dioxins and furans in fly ashes from a medical waste incinerator was determined following the US EPA 8280A protocol. Dioxin emissions in both particulate matter and exit gas stream from the incinerator’s chimney were estimated. Furthermore,

Synthesis and Anti-Tuberculosis Activity of Substituted 3,4-(dicoumarin-3-yl)-2,5-diphenyl Furans and Pyrroles

Engineering Proceedings, 2022
Increasing rates of multi-drug resistant (MDR) and extremely-drug resistant (XDR) cases of tuberculosis (TB) strains are alarming, and eventually hampered an effective control of the pathogenic disease. In the present study, nine derivatives of 2,3-bis(2-
