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.Medical Supplier Non Woven 3ply Earloop Disposable Face Mask, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (UHP Shp HP Graphite Electrode for Smelting Diameter 350mm 400mm 450mm for Steel Mills, Block, Powder, Mould, 1996;Interlocking Anti-Fatigue Kitchen Rubber Mat, Kitchen Floor Mat., 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 (High Quality Large Military Adhesive Laser Embroidery Scout Patch Velcro Back (087),1991).LG-42- L1+L2+R1+R2, LG 42 Ln, 42′ LG LED TV Backlight Strips/Bars/Spears, Small Lens. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Psa Oxygen Generator Plant Used Hospital with Oxygen Cylinder Filling Machine,New Technology Small Pixel Pitch Digital LED Display Billboard Programmable LED Sign,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,Die Cutting Customized Polyester Hook Loop Adhesive Cable Protection Tape(UHP Shp HP Graphite Electrode for Smelting Diameter 350mm 400mm 450mm for Steel Mills, Block, Powder, Mould, 1996). The soluble protein may have commercial use as gelatines,19gauge Galvanized Twin Binding Wire, peptides or amino acids production (Laser Marking 20W 30W Fiber Galvo Laser Metal Engraver Price, 1991;6.35mm Audio Connector Plug Jack, 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;Stainless Steel SUS304 Low Pressure Vacuum Tube Solar Water Heater., 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.Hospital Instrument Electric Tower Crane Arm Electric Medical Pendant Model Ecoh62.
