    Abstract The promoters of high-affinity hexose transporter, HXT6 and HXT7, are sufficient for complementary expression of invertase to restore the growth of Saccharomyces cerevisiae in raffinose medium. The HXT7 promoter produced higher invertase activity at 139- and 30-fold of the basal activity in strains GN 3C.2 and W303-1, respectively. In addition, the HXT7 promoter expressed 3- to 9-fold more of enhanced green fluorescent protein than that of the constitutive ADH1 in three different S. cerevisiae strains, even during short-term incubation in glucose medium. Therefore, HXT7 promoter could be used for heterologous protein expression in S. cerevisiae.

    Abstract Aspartokinase III, encoded by lysC, is responsible for the first step of lysine biosynthesis in Escherichia coli. In this study, a lysC knockout E. coli W3110 strain was generated to study the differential gene expression profiles of wild type and lysC knockout strains. Several significant changes were observed, including biosynthesis of lysine, oxaloacetate, alpha-ketoglutarate and glutamate genes. Genes related to transporters and heat shock proteins were also affected by lysC knockout. The results indicated that the lysC knockout strain exhibited some phenomena similar to lysine starvation. The data generated by this study further clarify the systematic role of lysC in lysine biosynthesis.

    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.
