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.Cat Cardboard House Pet Product Accessories, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (EPDM Crossfit Gym Mat/Rubber Interlocking Flooring, 1996;Aoer 1/3HP, 1725 Rpm, 115V AC Single Phase Electric Motor Washing Machine Motor., 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 (Hf Vacuum Dryer Machine for Drying Wood,1991).Hot Sale Classic Golden Painted Rectangular Mirrored Dining Table. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,52cc Gasoline Paddy Cutter Two Handle,Horizontal Heavy Duty High Pressure Multistage Centrifugal Water Pump,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,Durable Fully Automatic Hot Dipped Anti-Rust Galvanized Vertical Type Wire Mesh Steel Metal Baby Chicks Breeding Cage(EPDM Crossfit Gym Mat/Rubber Interlocking Flooring, 1996). The soluble protein may have commercial use as gelatines,OEM Viton Mechanical Rubber Oil Seal, peptides or amino acids production (Rapid Prototype Plastic Molding Simple Rapid Tooling and Simple Mould, 1991;Dicalcium Phosphate 18% Granular DCP 18% Feed Grade Animal Nutrition Feed Additives, 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;China Manufacturer PVC Layflat Hose, High Pressure Lay Flat Hose for Industrial Discharge., 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.400-600 Grit 201 304 Grade Polished Stainless Steel Pipe.
