25. Oxidação umida catalitica da lignina em reatores trifasicos com produção de aldeidos aromaticos
The lignocellulosic material, representing the largest natural renewable resource, occurring in the plants under the cellulose form, hemicellulose, lignin and extractive, with the lignina corresponding about 30% of this total one. The routes of lignin chemical processing, with prominence for the oxidations processes, with the objective of vanilin production,

26. Modeling and simulation of oxidativos processes of the natural gas / Modelagem e simulaÃÃo de processos oxidativos do gÃs natural
Computational simulations in transient regimen had been carried through in order to study the partial oxidation for the synthesis gas production and attainment of methanol saw gas of synthesis in reactors of catalytic fixed bed. The considered dynamic mathematical models for the reactors had formed sets of partial distinguishing equations that had been solve

27. Anaerobic Methane Oxidation: Occurrence and Ecology
Anoxic sediments and digested sewage sludge anaerobically oxidized methane to carbon dioxide while producing methane. This strictly anaerobic process showed a temperature optimum between 25 and 37°C, indicating an active microbial participation in this reaction. Methane oxidation in these anaerobic habitats was inhibited by oxygen. The rate of the oxidation

28. Identification of putative methanol dehydrogenase (moxF) structural genes in methylotrophs and cloning of moxF genes from Methylococcus capsulatus bath and Methylomonas albus BG8.
An open-reading-frame fragment of a Methylobacterium sp. strain AM1 gene (moxF) encoding a portion of the methanol dehydrogenase structural protein has been used as a hybridization probe to detect similar sequences in a variety of methylotrophic bacteria. This hybridization was used to isolate clones containing putative moxF genes from two obligate methanotr

29. Isolation and Characterization of a Thermophilic Bacterium Which Oxidizes Acetate in Syntrophic Association with a Methanogen and Which Grows Acetogenically on H2-CO2
We previously described a thermophilic (60°C), syntrophic, two-membered culture which converted acetate to methane via a two-step mechanism in which acetate was oxidized to H2 and CO2. While the hydrogenotrophic methanogen Methanobacterium sp. strain THF in the biculture was readily isolated, we were unable to find a substrate that was suitable for isolatio
