    摘要: The present disclosure pertains to a genetically modified microorganism that satisfies some of specific requirements. The specific requirements include: (I) compared to a wild type microorganism, having reduced or inactivated succinate dehydrogenase activity or fumarate reductase activity; (II) compared to a wild type microorganism, having reduced or inactivated lactate dehydrogenase activity; (III) having a modified phosphoenolpyruvate carboxylase activity and thus showing resistance against the feedback inhibition by aspartic acid in wild type phosphoenolpyruvate carboxylase activity, or having an exogenous phosphoenolpyruvate carboxylase activity and thus showing higher resistance against the feedback inhibition by aspartic acid than wild type phosphoenolpyruvate carboxylase activity shown by a wild type microorganism; and (IV) compared to a wild type microorganism, having reduced or inactivated pyruvate : quinone oxidoreductase.

    摘要: The present invention relates to a method for producing a recombinant protein, the method including: a first step of culturing a recombinant cell expressing a recombinant protein under control of an inducible promoter in a medium containing galactose and at least two selected from the group consisting of mannitol, raffinose, and melibiose; and a second step of further culturing the recombinant cell under a condition that expression from the inducible promoter is induced after the first step.

    摘要: The present invention relates to a modified fibroin including a domain sequence represented by Formula 1: [(A) n motif-REP] m or Formula 2: [(A) n motif-REP] m -(A) n motif, and having a serine residue content rate of less than 5.5%. [In Formula 1 and Formula 2, the (A) n motif represents an amino acid sequence consisting of 4 to 27 amino acid residues, and the number of alanine residues with respect to the total number of amino acid residues in the (A) n motif is 80% or more. REP represents an amino acid sequence consisting of 10 to 200 amino acid residues. m represents an integer of 10 to 300. The plurality of (A) n motifs may be the same amino acid sequence or different amino acid sequences. A plurality of REPs may be the same amino acid sequence or different amino acid sequences.]

    摘要: The objective of the present invention is to provide a transformed Aspergillus microorganism lacking at least two types of selection marker genes available for marker recycling method and a composition therefor. The objective can be achieved by a transformed Aspergillus microorganism lacking at least two types of selection marker genes available for marker recycling method on its chromosomes, or a composition for transforming an Aspergillus microorganism containing at least two types of nucleic acid fragments containing a loop-out region and a selection marker gene available for marker recycling method between homologous recombination regions, wherein the selection marker genes contain a tryptophan biosynthesis gene and a gene different from tryptophan biosynthesis gene.
