There is a need to explore lignocellulosic materials to select an adequate substrate for lignocellulolytic enzyme production. Utilization of some residues provides an opportunity to produce high yields of lignocellulolytic enzymes in a simple medium.The aim of the present work was to study the effect of wood flour as a carbon source on the cellulolytic and xylanolytic secretion of white-rot fungi native from Misiones.Fungi were incubated with 5 g Pinussp. wood flour/L and 5g Eucalyptussp. wood flour/L as carbon sourcesin a reciprocal shaker at 80 rpm and 29ºC for 15 days. Total cellulase, endo-1,4-β-glucanase, β-glucosidase, cellobiohydrolase and endo-1,4-β-xylanase activities were determined in culture supernatants.Tested fungi showed high endo-1,4-β-xylanase activity between 6 and 12 days. Total cellulase showed the highest activity between 12-15 culture days. The test did not show differences among Pycnoporus sanguineusLBM 014, P. sanguineusBAFC 2126, Irpex lacteusBAFC 1171, Irpexsp. LBM 032, Irpexsp. LBM 034 and Lenzites elegans BAFC 2127, showing the highest activity for thisgroupregard the others strains. I. lacteusBAFC 1171 was the strain with major endo-1,4-β-glucanase activity at day 9 (847U/L). In the case of β-glucosidase and cellobiohydrolase, P. sanguineusBAFC 2126 was the strain with the highest activity between 12-15 culture days (18 U/L), and between 9-15 culture days (39 U/L), respectively. Wood flour proved to be a suitable carbon source to produce hydrolytic enzymes. I. lacteusBAFC 1171 and P. sanguineusBAFC 2126 have potential for cellulase production whereas P. sanguineusLBM 008 is a goodendo-1,4-β-xylanase producer. 2015-11-10 info:eu-repo/semantics/article info:ar-repo/semantics/artículo info:eu-repo/semantics/publishedVersion https://hdl.handle.net/20.500.12219/4472 eng info:eu-repo/semantics/altIdentifier/urn/https://rajpub.com/index.php/jbt/article/view/4855/pdf_58 info:eu-repo/semantics/openAccess application/pdf application/pdf 680.4 KB Council for Innovative Research |
