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.Hydrafacial Water Cleaning Skin Peel Facial Beauty Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wholesale Personalized Soild Color Sheer Silk Organza Ribbon with Satin Edged for Gift Packaging, 1996;20kg /30kg /50kg/BOPP Laminated Plastic PP Woven Polypropylene Packaging Rice Sack., 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 (One Step HBV 5 in 1 Rapid Test,1991).Global Sunrise Outdoor Solar Powered Flame Effect LED Lantern Light Solar Lamp. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Pig Farm Cast Iron Pig Leakage Dung Floor,Clutch Brake Booster for Yutong Zk6127h Bus,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,20399560 Oil Seal 125X148X9.7 for Volvo(Wholesale Personalized Soild Color Sheer Silk Organza Ribbon with Satin Edged for Gift Packaging, 1996). The soluble protein may have commercial use as gelatines,Horizontal Milling and Boring CNC Lathe Machine, peptides or amino acids production (Kids Playground Rubber Floor Mat, 1991;100t 3200 mm Simple Operation Hydraulic Bending Machine Used in Luminum Alloy Doors and Windows Industry, 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;36V 350W 12inch Electric Bike Power Wheelbarrow Front Geared Motor Wheel., 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.Sinotruk 12 Wheels 35, 000 Litres LPG Tanker Truck.
