BIOTRANSFORMACIÓN DE LOS SUSTRATOS 2-FENILETANOL Y ACETOFENONA CON EL HONGO FITOPATÓGENO Colletotrichum acutatum/ BIOTRANSFORMATION OF 2-PHENYLETHANOL AND ACETOPHENONE BY THE PLANT PATHOGENIC FUNGUS Colletotrichum acutatum/ BIOTRANSFORMAÇÃO DOS SUBSTRATOS 2-FENILETANOL E ACETOFENONA COM O FUNGO FITOPATOGÊNICO Colletotrichum acutatum

Resumen en portugués Neste estudo foi analisada as biotransformaçoes feitas pelo fungos fitopatogênico Colletotrichum acutatum, nos substratos 2-feniletanol 1 e acetofenona 2; os processos forem feitos no meio de cultura Czapeck-Dox a uma temperatura média de 24 °C, umidade relativa entre 45 e 60% e agitação 150 rpm em um agitador orbital tipo shaker. Na biotransformaçao do substrato 1 é obtido os produtos metabólicos 1-fenil-1,2-etanodiol 3, (2-metoxietil) benceno 4 e acetato de 2-f (mas) eniletilo 5, e do substrato 2 os compostos 1-fenil- 1,2-etanodiol 3, 1-feniletanol 6 e 2- feniletanol 1. Os produtos da transformação microbial forem identificados por meio do cromatografia de gás acoplada ao espectrometria da massas (CG-EM) e ressonância magnética nuclear de hidrogênio e de carbono (RMN 1H e 13C). Uma tendência marcada do patógeno é observada para produzir hidroxilaçoes na cadeia lateral do anel aromático; também tem a capacidade de reduzir ao grupo carbonilo e esterificar dos grupos hidroxilo da função álcool primária. Uma rota metabólica possível para a transformação das substratos é discutida. Resumen en español En este estudio se evaluaron las biotransformaciones realizadas por el hongo fitopatógeno Colletotrichum acutatum, sobre los sustratos 2-feniletanol 1 y acetofenona 2; los procesos se realizaron en el medio de cultivo líquido Czapeck-Dox a temperatura promedio de 24 oC, humedad relativa entre 45 y 60%, y agitación a 150 rpm en un agitador orbital tipo shaker. En la biotransformación a partir del sustrato 1 se obtuvieron los productos metabólicos 1-fenil-1,2-etanodiol (mas) 3, (2-metoxietil) benceno 4 y acetato de 2-feniletilo 5, y desde el sustrato 2 los compuestos 1-fenil-1,2-etanodiol 3, 1-feniletanol 6 y 2-feniletanol 1. Los productos de la transformación microbiana se identificaron mediante cromatografía de gases acoplada a espectrometría de masas (CG-EM), y resonancia magnética nuclear de protón y carbono (RMN 1H y 13C). Se observó una tendencia marcada del patógeno a producir hidroxilaciones sobre el sustituyente del anillo aromático; igualmente, tiene la capacidad de reducir el grupo carbonilo y esterificar los grupos hidroxilo de alcoholes primarios. Se discute una posible ruta metabólica para la transformación de los sustratos. Resumen en inglés The microbial transformation of 2-phenilethanol 1 and acetophenone 2 was investigated using the plant pathogenic fungus Colletotrichum acutatum; the process was carried out in liquid media culture Czapeck-Dox at an average temperature of 24 oC, a relative humidity between 45% and 60% and with agitation in a shaker at 150 rpm. The biotransformation of the substrate 1 produced the metabolic products 1-phenyl-1,2-ethanediol 3, (2- methoxyethyl)benzen 4 and 2-phenylethyl acet (mas) ate 5, and from substrate 2 were obtained the compounds 1-phenyl- 1,2-ethanediol 3, 1-phenylethanol 6 and 2-phenylethanol 1. The structures of metabolic products were determined by gas chromatography coupled with mass spectrometry (GC-MS) and nuclear magnetic resonance of proton and of carbon (1H and 13C NMR). The process has a strong tendency of the pathogen to produce hydroxylations on the substituents attached to the aromatic ring. Additionally, C. acutatum was effective to reduce the carbonyl group and produce esterification reactions in the hydroxyl groups from primary alcohols. The metabolic pathway of both substrates is discussed.
