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.New Technology Carbon Cleaning Tools Auto Accessories, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Environmental Test Salt Spray Tester Price, 1996;Custom 2 Ring Binder PP Lever Arch Clip File Folder., 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 (Quantum Science Lava Stone Pendant Necklaces Scalar Energy Pendant,1991).TUV Approved Y Splitter 2 Way Solar Mc4 Y Branch Connector. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,CNC Laser Customized Telescopic Steel Cover,High Precision Mini Laser Cutting System,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,Mill Finish Black Steel Grating Stock Panel Grating From Ningbo Jiulong(Environmental Test Salt Spray Tester Price, 1996). The soluble protein may have commercial use as gelatines,1350ml Round Shape Borosilcate Lunch Box Office Used (GB13G17195), peptides or amino acids production (One to One Order Following Strong Real Gold Thread, 1991;New Design Paper Pyramid Memo Cube with Ribbon for Promotion, 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;Plastic Medallion, Plastic Ceiling Rose., 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.PP PE PVC Single Wall Corrugated Pipe Making Machine Line.
