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.Wholesale Fashion Handbags Clutch Coin Purse White Ladies PU Wallet, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Aiyos New Floor Standing 55 Inch Narrow Bezel Touch Screen Advertising Interactive Kiosk, 1996;Dual Plastic 9 Volt Battery Clips Connector with Wire., 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 (Precision Ball Screw with Two Nut,1991).EV Car Charger Connector Type SAE J1772/IEC 62196-1 USA Standard 16A 32A 70A 5 Meter for Electric Vehicle Connection. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Low Density Cleaner in Paper Making Machine,En471 Reflective Fabric Tape Cintas Reflectantes De Tela Plateada,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,Customized Stainless Steel Laser Cutting(Aiyos New Floor Standing 55 Inch Narrow Bezel Touch Screen Advertising Interactive Kiosk, 1996). The soluble protein may have commercial use as gelatines,Price of a Retail Supermarket Push Cart for Sale, peptides or amino acids production (Indoor UTP Cat 6 with Rj 45 Connector Length 20 Meter Cable, 1991;OEM Stainless Steel Stamping Parts Custom Stainless Steel Sheet Fabrication Metal Stamping Fabricate, 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;Handmade Natural Bamboo Basket / Bamboo Flower Pot., 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.Stainless Steel Handrail Bar Holder for 16mm Pipe.
