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.Mass Stock Yl10.2 Carbide Rods for Milling 45HRC, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Heavy Industry Electric Transport Vehicle on Rails, 1996;Manual Interlocking Brick Making Machine., 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 (A100-T32-S2-C 2 Way 1 1/4′′ SS316 Electric Control Water Ball Valve,1991).Direct Factory Suppy Electric Razor Barbed Wire Low Price for Fencing. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Plastic Blow Molding Machine, Jar Blower, Jar Blow Molding Machine, Perfroms Blow Moulding Machine,Needlle Punched Pet/PP 200G/M2 Non Woven Geotextile,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,Metal Gold Marathon Running Sport Medal for Promotion Gift(Heavy Industry Electric Transport Vehicle on Rails, 1996). The soluble protein may have commercial use as gelatines,12V90AH Front Access Terminal Communication Power Cabinet Telecommunication Projects EVolt ebn Battery, peptides or amino acids production (Security Shopping Trolley Baby Seat for Supermarket Cart, 1991;Desktop & Walmount Workstation with Gas Lift Floorbase Double Monitor 10-24, 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;Minimalism Small Portable Laser Engraver Fiber for Metal Plastic Key Gun Rubber PVC Glass Yeti Cup., 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.Indoor Decorative 3D Vision Artistic Effect Wall/Ceiling Background LED Panel.
