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.Wholesale China Motorcycle Engines Parts Piston Pin for Vespa125, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Two Layer License Plates with Wide Border Embossed, 1996;Electrical Barber Shop Equipment Electric Hair Curling Wand Iron., 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 (Really Microfiber PVC Leather for Sofa Furniture,1991).94V0 Circuit Board Mobile Phone PCB Motherboard. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Heat Resistant Pyrex (borosilicate) Glass Food Storage Containers,PP Gear Operate Plastic Butterfly Valve for Industrial by JIS&Lug Plastic Valve/ Water Valve/ Industrial Valve,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,Adhesive Powder for Skim Coat/Wall Putty HPMC(Two Layer License Plates with Wide Border Embossed, 1996). The soluble protein may have commercial use as gelatines,4X4 Galvanized Welded Wire Mesh Panel (FACTORY), peptides or amino acids production (Cotton Yarn Computerized Lace Knitting Machine, 1991;Plastic Caps Making Machine / Injection Molding 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;Corrugated Rust Proof Coating Sheet/ Prepained Galvanzied Steel Roof Plate., 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.Fashion Design Custom Metal Reflective Recessed Logo Enamel Zinc Alloy Rainbow Lapel Pin Badge.
