dig-irnas-es-10261-560672018-09-11T12:09:01Z Analysis of chemical changes in Picea abies wood decayed by different Streptomyces strains showing evidence for biopulping procedures Arias Fernández, Mª E. Rodríguez Bullido, Juana Pérez Leblic, Mª I. Hernández Cutuli, M. Polvillo, Oliva González-Pérez, José Antonio González-Vila, Francisco Javier Comisión Interministerial de Ciencia y Tecnología, CICYT (España) 10 pages, 1 figure, 2 tables, 24 references. The present study is focused on analysing the suitability of different Streptomyces strains for biomechanical pulping purposes using spruce wood (Picea abies) as substrate. After 2 weeks of incubation, no apparent variations in lignin Klason content of treated woods were detected compared with the control. However, the increase in acid-soluble lignin fraction pointed out chemical alterations in lignin moiety. Through Py-GC/MS analysis enrichment in cellulose and lignin molecule modifications were detected in treated woods. The increase in the relative abundance of the most G-type phenol units with a higher oxidation degree suggests that some oxidation occurred in the lignin C3-alkyl chain. In addition, the decrease in the phenylmethane? phenylethane/phenylpropane(phC1? phC2/phC3) ratio would indicate the ability of Streptomyces strains to breakdown the C3-alkyl chain linkages once carbons had been oxidized. From this study it could be concluded that the assayed strains are able to produce a delignification of spruce wood which may improve mechanical pulping processes. This work was supported by the Spanish CICYT Project CTQ2004-03441/PPQ.
