Deletion of sxlr in T. reesei.
a Schematic diagram of sxlr deletion in T. reesei 6a-u and RUT-C30. We used CRISPR/Cas9 system in the T. reesei QM6a background and the traditional method in the T. reesei RUT-C30 background. b PCR results for transformant identification. Three different transformants were chosen for verification. c The xylanase and cellulase activity of 7-day culture supernatant with wheat bran and Avicel as carbon sources. Error bars represent the standard deviation of three biological replicates
