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.Zinc Alloy Lid Zamak Alloy Casting Cap (STK-14-Z0069), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Transparent Color Stretch Wrap Film Manual Operate Wrap Film, 1996;Good Price Welding Electrode (e7018/e7018-1)., 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 (Ep/Nn/EPP Industrial Rubber Conveyor Belt,1991).Tpo Waterproof Membrane/Thermoplastic Polyolefin for Rooofing. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,New PP Plastic 24mm 28mm Liquid Cream Pump for Lotion Bottles Rd-238,Custom Logo Fleece Hoodies Men Pullover Neno Oversized Men′s Hoodies,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,Auto Spare Parts Ignition Coil Fp85-18-100c(Transparent Color Stretch Wrap Film Manual Operate Wrap Film, 1996). The soluble protein may have commercial use as gelatines,vacuum Pressure Impregnation CCA Wood Preservative Treatment Equipment, peptides or amino acids production (Flooded Type Water Cooled Screw Chiller, 1991;Promotional Custom Embossed Cups with Logo Print for Office/Holiday/Birthday, 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;Enameled Mini Cast Iron Casserole., 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.Good Quality Tomato Sauce Making Machine.
