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.100% Cotton Luxury Printed Bedding Comforter Set, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Mouse Pad with Gel Wrist Rest, 1996;Custom Size Christmas Gift Personalized Watch Boxes for Men., 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 (Best Selling Quality Aluminum Acetylene Gas Cylinder,1991).Coal Mine Mini Electric Excavator with Quick Coupling. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2000L Stainless Steel Micro Brewery Wine / Beer Conical Fermentation Tank,Food Grade Transparent Cookie Airtight Plastic Container Jars,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,Stainless Steel Sheet Metal Fabrication Switchgear Cabinet Factory(Mouse Pad with Gel Wrist Rest, 1996). The soluble protein may have commercial use as gelatines,Boho Gold&Silver Antique 3 Circle Hoops Pendant Earring for Women, peptides or amino acids production (Factory Direct Sale Single Cloth Hanger Hook, 1991;2 Round Sash Pulley for Chain - Brass (PVD), 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;Anodized Aluminum Expanded Metal Mesh Competitive Price., 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 DIP Galvanized G2150 D Ring Shackle.
