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.New Monocular Hunting Wargame Mini Scope Digital Night Vision, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Dual Function Double Use Both Cut Steel Sheet and Pipe Tube Metal Fiber Laser Cutting Machine, 1996;Atlas Copco Ga VSD Air Screw Air Compressor High Quality Stationary Electric Screw Air Compressor., 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 (Italy Design Good Quality Hydraulic Motorcycle Lift Table,1991).Wholesale Menthol E Liquid E Juice for EGO E Cigarettes. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Biodegradable Kraft Paper Soup Cup Instant Noodles Bowls with Lids,New Cisco Aironet 3700 Series Wireless Access Point Air-Cap3702e-B-K9,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,Portable Telescopic Straw Metal Drinking Straw with Brush Case(Dual Function Double Use Both Cut Steel Sheet and Pipe Tube Metal Fiber Laser Cutting Machine, 1996). The soluble protein may have commercial use as gelatines,Frameless Sliding Shower Enclosure in Bathroom with 8mm Clear Glass and Stainless Steel Hardware, peptides or amino acids production (Etching Rear Trunk Sill Plates for Hyundai Tucson, 1991;Quality Horizontal Flat Bed Metal CNC Turning Lathe Machine Price Ck6163, 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;Lab Equipment Sr Paper Pulp Beating Freeness Test Machine., 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.CREE COB Meanwell Driver Walkway Lamp 45W LED Canopy.
