Abstract
Strain W-10, originally identified as Trichoderma koningii, and its supposed mutant G-39, published for production and gene expression of cellulase and xylanase, demonstrated morphological characteristics distinct from those of T. koningii, respectively. To clarify the identification derived from morphological characteristics, several methods were used, including electrophoretic karyotyping, internal transcribed spacer (ITS) analysis of rDNA, and polymerase chain reaction (PCR) fingerprinting using the universal primer L45. All the molecular characteristics showed that strains G-39 and W-10 were identical to T. reesei and T. longibrachiatum, respectively. The results strongly supported that T. koningii G-39 and W-10 should be reassigned as T. reesei and T. longibrachiatum, respectively. Strain G-39 should be considered a mutant from T. reesei QM9414 whose spores were contaminated with those of strain W-10 during a laboratory operation. According to this, we declare that T. koningii G-39 and W-10 must be renamed as T. reesei and T. longibrachiatum, respectively.
