RESUMO
A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.
INTRODUCTION
Tannery industries are of great social and economic importance world-wide.Tree Root Grinder Stump Grinder, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Open Narrow Slot Kx Electrical Wire Cable Raceway Ducts/Yellow Jacket Cable Protector, 1996;Customization! Bdy380CD Horizontal Directional Drilling Machine., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (V Folding HDPE LDPE Coreless Degradable Star Sealing Corn Starch Trash Coreless Rolling Garbage Flat Plastic Bag Making Machine,1991).Hotel Laundry Flatwork Ironing Machine/Roller Machine / Linen Iron Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,6D Galvanic Facial Machine Eye Lifting Skin Care Beauty Equipment,Plastic Tk4100/T5577/S50/S70 Contactless RFID Card for Identification,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).
Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,Programmable Salt Spray Test Chamber for Corrosion Testing/Test(Open Narrow Slot Kx Electrical Wire Cable Raceway Ducts/Yellow Jacket Cable Protector, 1996). The soluble protein may have commercial use as gelatines,Professional Manufacturer Pure Wolfram Wire with High Purity 99.95%, peptides or amino acids production (FKM Bearing Oil Seal /Customized, 1991;Hot Selling Shandong Manufacturer 3 4 5 Inch Rubber Sealing Ring Joint UPVC Rrj Pipe for Water Supply and Sewage/Drainage 8kg Rate PVC Tubes, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;T Slot Aluminum Extrusion Ob4040b Aluminium Profile, Industrial Aluminum Profile., 1998).
This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Hot Sale Auto and Type Customized Car Paint Spray Booth by Ce.
