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.Hot Selling Free Sample Natural Fragrant Bath SPA Salt, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Custom FSTN Va COB Cog Segment LCD Display Module, 1996;Jc680 High Temperature Pressure Transmitter., 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 (Deep Hole Cylinder Boring Machine for Sale,1991).Hot Selling 202 Stainless Steel Coil. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,NPK 16X Hammer Spare Parts Racing Forged Piston,2PC Flanged&Threaded, Wcb&CF8&CF8m, Floating&Trunnion Ball Valve,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,Compatible FHG EGG 1B 2 3 4 5 6 7 8 10 12 14 16 Pins Elbow Plug/Fixed Socket Push-Pull Metal Connector(Custom FSTN Va COB Cog Segment LCD Display Module, 1996). The soluble protein may have commercial use as gelatines,Mobile Hydraulic Concrete Placing Boom, peptides or amino acids production (Jcb Spare Parts for 3cx and 4cx Oil Cooler 923/02700, 1991;Heavy Duty 22oz PVC Vinyl Flatbed Cargo Tarpaulin Roll, 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;Cr1000 Spray Nozzle Common Rail Injector Tester., 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.Industrial Cast Steel Flanged One Way Swing Check Valve Nrv.
