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.Garden Decoration Marble Stone Granite Small Angel Sculpture Water Fountain, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (530ml Glassware/Glass Jar/Wine Bottle/Liquor Bottle/Spirits Bottle/Glass Vodka Bottle, 1996;PCB Connector Pin Connector 1.0 Pitch Dual Row Pin Header., 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 (Sdlg LG936L Wheel Loader Spare Parts 4041000687 Hose Assembly,1991).Galvanized Roller Shutter Window Torsion Springs. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,100 Ton 200 Ton Bending Cutting Straightening Machine H Frame Hydraulic Press for Sale,Carbon Graphite Crucible,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,Decorative Aluminum Solid Panel for Commercial Building(530ml Glassware/Glass Jar/Wine Bottle/Liquor Bottle/Spirits Bottle/Glass Vodka Bottle, 1996). The soluble protein may have commercial use as gelatines,Cummins ISBE truck diesel engine motor parts 3940059 camshaft bushing, peptides or amino acids production (Di DIN3352 Double Orifice Automatic Air Release Valve Dn65, 1991;Magic Hair Twist   Curl Sponge Brush, 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;Clearing Clogged Effectively Pipe Drain Cleaning Machine (A75)., 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.Geyi Disposable Laparoscopic Visible Optical Trocar.
