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.Pure Water Cutting Head Assy for Waterjet Cutting Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Kitchen Piece Multi-Function Rectangular Non-Slip Heat-Resistant Pad Coaster Cushion Tablecloth Table Silicone Table Mat, 1996;Latest Lace Fabric Design Logo Flag Embroidery Patch., 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 (China Economic Customized Design Steel Frame Farm Buildings Poultry Farm House for Chicken,1991).High Pressure 2 1/2 Hose Crimper Machine From Kangmai Hydraulic. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Auto Parts Window Regulator Switch for Mercedes Benz 213 905 15 05,New H Type Battery Cage System for Layer Chicken Farm,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,Calcined Petroleum Coke as Best Recarburizer in Iron Industry(Kitchen Piece Multi-Function Rectangular Non-Slip Heat-Resistant Pad Coaster Cushion Tablecloth Table Silicone Table Mat, 1996). The soluble protein may have commercial use as gelatines,X15 Power Monitor Two Way Live Stage Monitor Speaker System, peptides or amino acids production (Australia White High Quality Elegant Wood Window Plantation Shutters, 1991;Big Smart Hydroponic Planter Indoor Garden Light, 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;Fluorine Lined Butterfly Valve Flanged Type Anti Corrosion., 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.Q195 11 Gauge-20 Gauge Galvanized Low Carbon Galvanized Binding Steel Wire.
