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.Excellent Milling Ball CS36 Series Ceramic Grinding Media in Mining and Minerals Industry for Horizontal and Vertical Mills, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Fancy Hotel One Seat Fabric Hotel Molded Sofa Chinese Furniture Customization Upholstery for Hilton Hospitality Hotel Bedroom Furniture Luxury Supplier, 1996;Adjustable Aluminum Solar Mounting System., 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 (Wholesale Wireless Cheapest Android 2D Barcode Scanner,1991).Factory Price Diamond Wire Mesh Chain Link Fence. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Electric Heating Mantle 5L,Luxury Aroma Reed Diffuser with Rattan Sticks for Decoration,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,99% 3- (2-NITROPROP-1-ENYL) Thiophene CAS 149977-36-6 for P2np Intermediate(Fancy Hotel One Seat Fabric Hotel Molded Sofa Chinese Furniture Customization Upholstery for Hilton Hospitality Hotel Bedroom Furniture Luxury Supplier, 1996). The soluble protein may have commercial use as gelatines,Outdoor IP65 LED Flood Light 10W 20W 30W 50W 100W High Power LED Floodlight, peptides or amino acids production (Colorful Kinetic LED Vertical Tube DMX RGB Pixel Tube, 1991;Best Seller Hot Sale Compatible Lemos Feg 2b 26 Pin Metal Circular Push Pull Self Latching Connector, 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;FRP GRP Fiber Reinforced Plastic Fiberglass Gratings., 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.Customized Length Medical Suction Connecting Tube with Yankauer Handle Crowed/Standard Tip.
