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.Hand Push Thermoplastic Paint Pedestrians Line Road Marking Machine Price, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (50mm/75mm/100mm/150mm/200mm/300mm EPS/PU/PIR/PUR/Polyurethane/Rock Wool Sandwich Panel for Steel Structure/Cold Storage Roof and Wall Insulation, 1996;5/2 Way 3/2 Way Shift Airtac Namur Solenoid Valve., 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 (600mm Warehouse No Power Roof Fan,1991).Small Brown Glass Bottles. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Custom High Quality Resealable Zipper Flat Bottom Stand up Pouch Animal Feed Plastic Packing Bag,Low Price 750W 1000W 1500W 2000W 3000W 4000W 6000W Combined Fiber Metal Laser Cutting Machine Sheet and Pipe,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,RF China Professional Manufacturer Direct Way Manual Ball Valve(50mm/75mm/100mm/150mm/200mm/300mm EPS/PU/PIR/PUR/Polyurethane/Rock Wool Sandwich Panel for Steel Structure/Cold Storage Roof and Wall Insulation, 1996). The soluble protein may have commercial use as gelatines,Hollow Polycarbonate Sheet--Polycarbonate 100% Ge Lexan/ Bayer and UV Protected, peptides or amino acids production (Stainless Braided PTFE Hose R14 Standard Pipe, 1991;SPA and Beauty Service Air Cleaning Ultrasonic Air Diffuser, 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;Black Steel ASTM A192 Seamless Pipe Sch120., 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.Raw Material Adhesive NBR Latex of Latex Long Gloves.
