Protective role of hematin in alcohol oxidase-mediated glycerol oxidation: A kinetic modeling approach.

Mathematical modeling of complex multi-catalytic reaction pathways is a powerful tool not only for determining optimal operational conditions but also for gaining insights into the kinetic behavior of efficient yet product-sensitive enzymes. This approach was applied to the biooxidation of glycerol using oxidases, aided by hematin, a natural mimic of heme peroxidases and catalases, which acts as a scavenger for enzymatically produced HO. The bi-catalytic reaction system was coupled with the formation of a colored imine product from phenol and 4-aminoantipyrine, enabling spectrophotometric monitoring of reaction kinetics.

Pyrolysis and copyrolysis of three lignocellulosic biomass residues from the agro-food industry: A comparative study.

In this study, pyrolysis of residual biomass from the agro-alimentary industry of Argentina was investigated. The studied biomasses were rice husk, peanut shell and wheat straw. The effect of pyrolysis temperature over solid (bio-char), liquid (bio-oil) and gas (bio-gas) fractions weight yields were evaluated for each biomass, in the range of 350-650 °C.
