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.Wheel-Type-Carriage Precision Heavy Duty Linear Guide, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Double-Offset Double Flanged Stainless Steel Butterfly Valve, 1996;Automotive Acrylic Wholesale Masking Tape Factory Price., 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 (Home Decoration Candle Glass Holder for Table Decorative,1991).Wholesale Wooden Lid Borosilicate Jam Honey Storage Glass Jars. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Wholesale Black Galvanized Head Stainless Steel Screw,Hardware Rigging Galv Zinc Plated M10 Eye-Hook DIN1480 Turnbuckle,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,Outdoor Dining Table Set Stainless Steel Table Mesh Fabric Chair(Double-Offset Double Flanged Stainless Steel Butterfly Valve, 1996). The soluble protein may have commercial use as gelatines,OEM Logo Soft Silicone Reusable BPA Free Drinking Straws, peptides or amino acids production (Coated Waterproof Tarp Fabric Sheet Cover PP/PE Tarpaulin, 1991;4 Drawer Steel Office Vertical Filing Cabinet, 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;12V Kids Ride on Remote Control Battery Powered Electric Toy RC Car., 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.Parts for Crane Outrigger Hydraulic Oil Cylinder.
