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.Dark Blue Color Texture Indoor Swimming Pool Glass Mosaic Tile, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cable Tray with ′t′ Slots, 1996;10 Gauge Galvanized Welded Wire Mesh for Construction Using., 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 Factory Inline Hockey Skate Puck,1991).0.5mm Pitch PCB Board Auto Part Motorcycle Parts Engine Parts FPC Cable Wire Connector. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,201 301 304 Embossed Checkered Plate Stainless Steel Coil/Sheet,Disposable PS Foam Fast Food Box Making Machine,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,Suoer 12V 220V 3000W Pure Sine Wave Inverter (FPC-D3000A)(Cable Tray with ′t′ Slots, 1996). The soluble protein may have commercial use as gelatines,Best Stereo Amplifier Sound System Amplifier Price Fp22000q PRO Audio Power AMP, peptides or amino acids production (Foska Good Quality Plastic Stapler Set with Staples, 1991;Best Selling Counter Balance Forklift 3 Ton LPG Forklift Truck, 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;Hotel SPA Swimming Pool, Sport Room, Bathroom Towel., 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.Powerful Cleaning Colorful Scouring Pad for Kitchen Use.
