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.Carbide Mould Parts Moulding Parts, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Compression Mens Customized Gym Shorts Sportswear, 1996;Hot Sale Prime Hot Dipped Galvanized Steel Coil/Band/Tape/Strip., 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 (99.8% High Aluminium Oxide Low Na2o Calcined Alumina Powder,1991).Plastic Anti-Static PMMA Transparent Coated Lenses Sheet Making Machine Extruder. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,P10 P16 P20 DIP Full Front Service Waterproof LED Panel Display,Electric Furniture Lift,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,Roller Shutter Slat and Panel Manufacturer and Complete Roller Shutter(Compression Mens Customized Gym Shorts Sportswear, 1996). The soluble protein may have commercial use as gelatines,Customized Stainless Steel Sheet Metal Cabinet Fabrication Electrical Cabinet, peptides or amino acids production (Construction Material Hoist Rack and Pinion, 1991;3000lb Small Boat Marine Electric Trailer Winch Power-in, Power-out, 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;Utl Supply Phoenix Contact Cage Clamp Dinrail Terminal Blocks., 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.Diamond Circular Tct Saw Blade for Cutting Wood/Marble Stone/Metal.
