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.Wholesale Wireless Cheapest Android 2D Barcode Scanner, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Factory Price Diamond Wire Mesh Chain Link Fence, 1996;Electric Heating Mantle 5L., 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 (Luxury Aroma Reed Diffuser with Rattan Sticks for Decoration,1991).99% 3- (2-NITROPROP-1-ENYL) Thiophene CAS 149977-36-6 for P2np Intermediate. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Outdoor IP65 LED Flood Light 10W 20W 30W 50W 100W High Power LED Floodlight,Colorful Kinetic LED Vertical Tube DMX RGB Pixel Tube,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,Best Seller Hot Sale Compatible Lemos Feg 2b 26 Pin Metal Circular Push Pull Self Latching Connector(Factory Price Diamond Wire Mesh Chain Link Fence, 1996). The soluble protein may have commercial use as gelatines,FRP GRP Fiber Reinforced Plastic Fiberglass Gratings, peptides or amino acids production (Customized Length Medical Suction Connecting Tube with Yankauer Handle Crowed/Standard Tip, 1991;Fashion Mens Long Zipper Credit Card Purse PU Phone Wallet with Strap, 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;48V DC Powered Air Conditioner for Outdoor Cabinet 2000W., 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.New Funfair Outdoor Sky Space Walk Tourist Bike Amusement Park Rides.
