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.Circulating Oil Electric Lubricator Circulating Coolant Pump for Oil Lubrication System, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (3W 5W 7W 9W LED Bulb E27 E14 B22 LED Bulb, 1996;High Efficiency Pineapple Canning Plant., 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 (Embossed Pattern PU Leather Classic Mens Wallet,1991).Cheapest 250ml 300ml 400ml 500ml 800ml Voss Glass Water Bottles. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Casting PE Film with Ash for Adult Diaper Back Sheet,Supra Brand Laundry Liquid Baby Formula,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,Customized Aluminum CNC Machinery Die Casting Aluminum Housing Car Interchanger(3W 5W 7W 9W LED Bulb E27 E14 B22 LED Bulb, 1996). The soluble protein may have commercial use as gelatines,Cleaning Products Sponge Vacuumized Pack 65mm, peptides or amino acids production (Mineral Water Bottle Mould Plastic Blowing Mold, 1991;High Quality Acrylic/PVC/Kt Foam Board, Outdoor Advertising Sign Boards, 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;6000PCS/H Automatically Paper Recycling Egg Tray Moulding 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.Class 1/Class 2 Birch Plywood for Automotive and Boatbuilding Applications.
