60 results about "Intestinal membrane" patented technology

The mucosa is the innermost tissue layer of the small intestines, and is a mucous membrane that secretes digestive enzymes and hormones. The intestinal villi are part of the mucosa. The three sections of the small intestine look similar to each other at a microscopic level, but there are some important differences.

Pharmaceutical proteins, human therapeutics, human serum albumin, insulin, native cholera toxic b submitted on transgenic plastids

Transgenic chloroplast technology could provide a viable solution to the production of Insulin-like Growth Factor I (IGF-I), Human Serum Albumin (HSA), or interferons (IFN) because of hyper-expression capabilities, ability to fold and process eukaryotic proteins with disulfide bridges (thereby eliminating the need for expensive post-purification processing). Tobacco is an ideal choice because of its large biomass, ease of scale-up (million seeds per plant), genetic manipulation and impending need to explore alternate uses for this hazardous crop. Therefore, all three human proteins will be expressed as follows: a) Develop recombinant DNA vectors for enhanced expression via tobacco chloroplast genomes b) generate transgenic plants c) characterize transgenic expression of proteins or fusion proteins using molecular and biochemical methods d) large scale purification of therapeutic proteins from transgenic tobacco and comparison of current purification / processing methods in E. coli or yeast e) Characterization and comparison of therapeutic proteins (yield, purity, functionality) produced in yeast or E. coli with transgenic tobacco f) animal testing and pre-clinical trials for effectiveness of the therapeutic proteins. Mass production of affordable vaccines can be achieved by genetically engineering plants to produce recombinant proteins that are candidate vaccine antigens. The B subunits of Enteroxigenic E. coli (LTB) and cholera toxin of Vibrio cholerae (CTB) are examples of such antigens. When the native LTB gene was expressed via the tobacco nuclear genome, LTB accumulated at levels less than 0.01% of the total soluble leaf protein. Production of effective levels of LTB in plants, required extensive codon modification. Amplification of an unmodified CTB coding sequence in chloroplasts, up to 10,000 copies per cell, resulted in the accumulation of up to 4.1% of total soluble tobacco leaf protein as oligomers (about 410 fold higher expression levels than that of the unmodified LTB gene). PCR and Southern blot analyses confirmed stable integration of the CTB gene into the chloroplast genome. Western blot analysis showed that chloroplast synthesized CTB assembled into oligomers and was antigenically identical to purified native CTB. Also, GM1,-ganglioside binding assays confirmed that chloroplast synthesized CTB binds to the intestinal membrane receptor of cholera toxin, indicating correct folding and disulfide bond formation within the chloroplast. In contrast to stunted nuclear transgenic plants, chloroplast transgenic plants were morphologically indistinguishable from untransformed plants, when CTB was constitutively expressed. The introduced gene was stably inherited in the subsequent generation as confirmed by PCR and Southern blot analyses. Incrased production of an efficient transmucosal carrier molecule and delivery system, like CTB, in transgenic chloroplasts makes plant based oral vaccines and fusion proteins with CTB needing oral administration a much more practical approach.

The invention discloses a method for treating sausage casing wastewater. The method comprises the following steps of: 1) sterilizing; 2) carrying out solid-liquid separation to obtain filtrate and protein-rich solid contents; 3) desalting, wherein the filtrate is passed through a nanofiltration device to obtain high salinity wastewater, amino acid solution and peptide solution; multiple-effect continuous crystallization is carried out on the high salinity wastewate to obtain crystallized salt and sausage casing recycle water; 4) crushing and pulping, wherein the protein-rich solid contents arecrushed and ground to obtain pulp; 5) carrying out enzymolysis, wherein amino acid, peptide solution and pulp are mixed and enzymolysis is carried out on the mixture; 6) concentrating, wherein the mixed solution is concentrated to obtain a concentrated material; and 7) carrying out spray drying, wherein the concentrated material is mixed with auxiliary materials, and spray drying is carried out to obtain an intestinal membrane protein powder. The invention provides the method for treating sausage casing wastewater, which combines a nanofiltration technology, a biological enzyme technology, ahigh salinity wastewater treatment technology and a spray drying technology; the method can meet requirements of sausage casing wastewater treatment, can bring economic benefits to enterprises, and ispracticable.

Suckling pig creep feed mixed feed and preparation method thereof

The invention discloses a suckling pig creep feed mixed feed which consists of the following raw materials in percentage by mass: national standard level-1 corn, national standard level-1 wheat, extruded full-fat soybean, extruded dehulled soybean meal, concentrated soybean protein, defatted fish meal, high-protein whey powder, edible glucose, high-quality soybean oil, coconut oil, calcium lactate, feed grade calcium hydrophosphate and gunk. The mixed feed is prepared by employing the production process of superfine grinding, mixing, pelletizing, cooling, grading and packaging. According to the suckling pig creep feed mixed feed, the conventional problems of low suckling pig creep feed protein, little suckling pig feed intake, high feed conversion ratio and slow weight increase within 10 days after breast-feed and ablactation are solved, the plasma proteins, intestinal membrane proteins and other protein raw materials homologous with pig organisms which bring danger of porcine virus diseases and the risk of possibly influencing and changing porcine biogenic genes are avoided, the suckling pig feed intake and daily gain are improved, and the feed conversion ratio is reduced.
