Abstract:
We isolated and characterized three strains of Penicillium; P. citrinum, P. chrysogenum and P. variabile from acidic mediums with kraft liquor as carbon’s source. We analyze their capacity to modify polyphenols. Preliminary assays confirmed the capabilities of these microorganisms to modify and degrade polyphenolic compounds like lignin. We demonstrate that they can grow in mediums with phenolic models and metoxilated compounds such as 3,4,5-trimetoxy benzaldehyde, syringic acid, resorcialdehyde, guaiacol and coniferyl alcohol, so they have the enzymes for oxidative, depolimerizating and demetoxilated reactions. The identification and characterization of these enzymes was made trough bioinformatics studies which allow us to relate different metabolic routes and enzymes from different genus and species. We also study the metabolism of Trichoderma reesei, isolated from Costa Rica’s mediums in order to use it as a consortium to modify polysaccharides. We believe that Penicillium’s consortium could modificate lignocelulosics in pretratement’s process for biofuel’s production or for chemist’s obtaining as modified phenols and their resins. We think that they reduce poliphenolic industrial residues. The use of this new efficient consortium of Deuteromycetes led us to innovate in traditional process for obtaining modificated phenols.
