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.Fire Protection Red Painted Ductile Iron Grooved Pipe Fitting, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Common Code Choke, Inductor, Line Filter, Ring Coil, Inductor, Choke Coil, 1996;High Efficiency Pure Sine Wave DC12V AC220V 1500W Power Inverter., 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 (Factory Custom Round Aluminum Tube 5154 5454 5652 5086,1991).Newest Adjustable Decline Bench Flat Weight Bench for Wholesales. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,PVC Wood Grain Decorative Sheet,Professional Ebony Wood Clarinet Bb Like Buffet Manufacturer,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,LED UV Portable Toothbrush Sterilizer(Common Code Choke, Inductor, Line Filter, Ring Coil, Inductor, Choke Coil, 1996). The soluble protein may have commercial use as gelatines,Precision Plastic Products, Auto Parts, Injection Moulds, Injection Molding, peptides or amino acids production (American NEMA Straight Blade Plug 30A 125V/250V Power Plug, 1991;10in 1500lb Pressure Seal Forged Steel Swing Check Valve, 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;Custom Printed/Embossed Black Earring Packaging Cards., 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.Mug Printing Machine Heat Press Promotion Brazil.
