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.Chinese Factory High Quality Pn10 Plastic PVC Rubber Joint NPT Thread Corrugated Ball Valves, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Solar Aluminum Rail Splice Connector for Rail Extention, 1996;Grade Aluminum Fly Fishing Thermometer., 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 (CNC Single Flute End Mill Milling Cutter Tools for Wood Milling,1991).Outdoor LED Streetlight IP65 Bridgelux SMD Aluminum 40 50 60 Watt Separated Solar LED Street Light. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Sc Fiber Optic Fast Connector,Jumbo Roll Tissue 2 Ply Toilet Paper Bathroom Tissue,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,10mm Cubes N52 NdFeB Block Magnets for Electronic Components(Solar Aluminum Rail Splice Connector for Rail Extention, 1996). The soluble protein may have commercial use as gelatines,Watermark Approval Brass Press Equal Fitting Male Tee, peptides or amino acids production (China Modern Steel Structure Layer Chicken Farm House Designs, 1991;Forged 316 Stainless Steel Marine Twisted Long D Shackle, 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;2.5X/3.5X Glasses Clip Dental Loupes Binocular Surgical Loupe Lab Medical Magnifier., 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.Outdoor UV Resistant Decoration Material WPC Exterior Wall Panels.
