A method for manufacturing a fermentation product by culturing a microorganism, the method containing steps (A) to (D): (A) culturing the microorganism with a first culture medium; (B) passing a culture solution containing cultured bacterial cells, raw materials for culture, and the fermentation product through an adsorption tower packed with an adsorbent capable of adsorbing the fermentation product from the culture solution, and then collecting an effluent containing the bacterial cells and the raw materials for culture flowing out from the adsorption tower, wherein a relationship among a size (short diameter) d of the bacterial cell, a pore size D1 of the adsorbent, and a minimum void size D2 between adsorbent particles, D1<d<D2 is satisfied; (C) eluting the fermentation product from the absorbent; and (D) culturing the microorganism with a second culture medium using collected effluent containing the bacterial cells and the raw materials for culture.

Provided herein are novel anti-CD28×anti-B7H3 (also referred to as “αCD28×αB7H3”) heterodimeric bispecific antibodies and methods of using such antibodies for the treatment of cancers. Subject αCD28×αB7H3 antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and targeting to B7H3 on tumor cells. Thus, such antibodies selectively enhance anti-tumor activity at tumor sites while minimizing peripheral toxicity. The subject antibodies provided herein are particularly useful for enhancing anti-tumor activity when used in combination with other anti-cancer therapies.

An isolated nucleic acid encoding an FX protein having a serine at position 79, a lysine at position 90, a leucine at position 136, an arginine at position 211, a serine at position 289, and a combination thereof is provided. Cells having a gene encoding a modified FX protein are provided, wherein the cells exhibit a reduced ability to fucosylate a glycoprotein at a first temperature, but exhibit the ability to fucosylate the glycoprotein at a second temperature. Methods and compositions for making glycoproteins with reduced fucosylation are provided.

A Trichoderma reesei mutant strain has a function of a polypeptide consisting of the amino acid sequence represented by SEQ ID NO: 2 is reduced. A method of producing a protein includes a step of cultivating the Tricho-derma reesei mutant strain, and a method of producing a cellulase includes a step of cultivating the Trichoderma reesei mutant strain.

The present disclosure relates to an isolated anti-FcRn antibody, which is an antibody binding to FcRn (stands for neonatal Fc receptor, also called FcRP, FcRB or Brambell receptor) that is a receptor with a high affinity for IgG or a fragment thereof, a method of preparing thereof, a composition for treating autoimmune disease, which comprises the antibody, and a method of treating and diagnosing autoimmune diseases using the antibody. The FcRn-specific antibody according to the present disclosure binds to FcRn non-competitively with IgG to reduce serum pathogenic auto-antibody levels, and thus can be used for the treatment of autoimmune diseases.

A mutant strain of a filamentous fungus of the genus Trichoderma having a reduced function of a polypeptide consisting of the amino acid sequence represented by SEQ ID NO: 2; and a method of producing a sugar from a cellulose-containing biomass, the method including: step a of producing a cellulase by cultivating a Trichoderma reesei mutant strain having a reduced function of a polypeptide consisting of the amino acid sequence represented by SEQ ID NO: 2, and step b of saccharifying the biomass by using the cellulase obtained in the step a.

Disclosed is a novel polyene-specific glycosyltransferase derived from Pseudonocardia autotrophica. The glycosyltransferase includes an amino acid sequence of SEQ ID NO: 1 and a gene encoding the glycosyltransferase. The glycosyltransferase is produced by a method which includes the steps of: culturing transgenic recombinant microorganisms; and isolating glycosyltransferase from the cultured recombinant microorganisms.
