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.ASTM Tp316 304 201 Square/Round Galvanized Stainless Steel Pipe for Chemical, Aerospace Equipment, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Komatsu Shantui Shehwa Zoomlion Liugong Dozer Steering Valve (16Y-76-22000 144-40-00100), 1996;Custom Black and White Segment Code Screen Electronic Scale LCD LCD Screen Digital Display Electronic Scale Dedicated LCD Screen., 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 (DIN7504 Stainless Steel Pan Head Philips Self Drilling Screw,1991).Auto Two Piece Folder Gluer for Corrugated Box. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,British Standard 2 Gang 1 Way Wall Light Switch,Vibratory Finishing Polishing Machine for Aluminum Brass Metal Steel Parts,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,Commercial Fitness Gym Strength Equipment Half Rack Body Solid Power Cage(Komatsu Shantui Shehwa Zoomlion Liugong Dozer Steering Valve (16Y-76-22000 144-40-00100), 1996). The soluble protein may have commercial use as gelatines,Amber Green Blue Transparent Spray Perfume Bottle Glass Bottle for Perfume, peptides or amino acids production (Natural Cannabidiol Cbd Isolate Powder Cbd Powder Cbd Oil CAS 13956-29-1 China Supplier, 1991;Two Head Mattress Machines Pocket Spring Coiling Machine Sewing Machine, 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;P-Level Sp-Level Mute Interchangeable Linear Motion Guide Rails., 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.Heavy Zinc Galvanized and PVC Coated Binding Cut Iron Wire Stainless Steel Wire.
