The invention relates to a modified cellulase derived polypeptide and application thereof, and belongs to the technical field of gene engineering and enzyme engineering. The invention provides a derivative polypeptide of cellulose excision enzyme Cel7A, the cellulose excision enzyme Cel7A is derived from Trichoderma reesei, NCBI Acession No.XM006969162.1, and the amino acid sequence of the cellulose excision enzyme Cel7A is as shown in SEQ ID NO: 1. The invention further provides a preparation method of the derivative polypeptide of the cellulose excision enzyme Cel7A. Wherein the amino acid sequence of the cellulose binding domain CBM is as shown in SEQ ID NO: 2. The derivative polypeptide is a polypeptide of which the amino acid sequence is 70% or more identical to that of a polypeptide shown in SEQ ID NO: 2, can reduce combination with lignin and improve the degradation efficiency of cellulose, so that the saccharification efficiency of cellulase is improved, the post-treatment process cost is greatly saved, and the derivative polypeptide is suitable for industrial production. The method has important industrial application value.

The invention relates to the technical field of coatings, and provides a coating for reducing the burning loss of a steel billet and a preparation method thereof.The coating for reducing the burning loss of the steel billet is prepared from, by weight, 15-20 parts of red mud, 10-16 parts of zirconium oxide, 2-4 parts of titanium oxide, 18-28 parts of silicon carbide, 6-9 parts of ferrous oxide, 5-8 parts of aluminum oxide, 12-17 parts of binder, 0.5-5 parts of water reducing agent and 18-28 parts of curing agent; the binder comprises the following components in parts by weight: 3-5 parts of a silica sol binder, 3-9 parts of magnesium aluminum silicate, 1-5 parts of magnesium acetylacetonate and 1-3 parts of a cellulose binder. According to the technical scheme, the problem that the effect of reducing the oxidation burning loss degree of a steel billet by a coating in related technologies is poor is solved.

Provided is a granule for suspension, which is a pharmaceutical composition including: a compound represented by formula 1:or a pharmaceutically acceptable salt or solvate thereof, a binding agent; and a dispersant. The binding agent includes a binding agent selected from the group consisting of a cellulose binding agent, a povidone binding agent, a vinyl alcohol binding agent, and a thickening polysaccharide binding agent. The dispersant is selected from the group consisting of an inorganic salt dispersant, an ether dispersant, a starch dispersant, a cellulose dispersant, and a fatty acid ester salt dispersant.

The present application discloses a composition comprising an adsorbent and a cellulose based binder that strongly adheres to a support and is flexible.
