Recent studies have reported that exposure of mammalian cells to microwave radiation may have adverse effects such as induction of cell apoptosis. However, the molecular mechanisms underlying microwave induced mammalian cell apoptosis are not fully understood. Here, we report a novel mechanism: exposure to 1800MHz microwave radiation induces p53-dependent cell apoptosis through cytochrome c-med...

This study used two different approaches to model changes in biomass composition during microwave-based pretreatment of switchgrass: kinetic modeling using a time-dependent rate coefficient, and a Mamdani-type fuzzy inference system. In both modeling approaches, the dielectric loss tangent of the alkali reagent and pretreatment time were used as predictors for changes in amounts of lignin, cell...

Lignocellulosic biomass is a promising feedstock for added value compound production in biotechnological processes such as solid-state fermentation (SSF). Although these solid materials can be directly used substrates fermentations state, pretreatment often required, especially if the microorganism selected unable to produce lignocellulosic enzymes. In present work, several strategies were appl...

Microwave torrefaction of oat hull was conducted to enhance its physicochemical properties. A bench-top reactor with an internal stirrer used for pretreatment at temperatures 225 °C, 255 and 285 residence times 3, 6, 9 min, respectively. Results showed that a high temperature level 3 min time or severe increased calorific values by up 35% original value, while decreasing mass yield down 60.77%....

Black pepper is one of Indonesia's agricultural commodities, contributing foreign exchange to the country. However, economic value this commodity has decreased. It influenced by lack diversified black products, which course, have a higher than raw material marketing. One product diversification that can be developed oil. In obtaining essential oils, appropriate methods and technology are needed...
