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.White Melamine Powder for Industrial Uses, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (UV Resistant Durable HDPE Reinforced Geomembrane HDPE, 1996;2070 4th Axis CNC, Atc CNC Router Machine, Carving Engraving Machinery with High Z Axis., 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 (Cheap Price Made in China Disposable Medical Heat Seal Flat Sterilization Pouch,1991).PE Film Blowing Machine (SJ-1000-1300-1500). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Eco-Friendly Summer Beach Lady Handmade Paper Shopping Straw Basket Bag,304 304L 904L 309S 310S Stainless Steel Design Checkered Plate,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,High Quality 0.38mm Color Yellow PVB Interlayer Film for Architecture Laminated Glass(UV Resistant Durable HDPE Reinforced Geomembrane HDPE, 1996). The soluble protein may have commercial use as gelatines,2017 Factory Directly Oversized Women Sunglasses, peptides or amino acids production (High Quanlity PTFE Thread Seal Tape, 1991;Fiberglass Grating, FRP Grating, GRP Grating, 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;Aluminium Profile Roller Shutters OEM/Rolling Screen Aluminium., 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.Rutile Titanium Dioxide Exterior Emulsion Paint.
