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.Headband Big Headphone EVA Bag Tool Case Specialized Storage Box, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hydraulic Fold-Bend Machine Hydraulic Bending Machine, 1996;Delphi Control Valve 28239295 (622B)., 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 (OEM Precision Aluminum Alloy/Zinc Alloy Die Casting,1991).Hot Sale Ink Chip for Epson P6070/P7070/P8070/P9070 Inkjet Printers. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Bathroom Makeup LED Mirror Glass with Light,Green PVC Coated Euro Fence Welded Wire Mesh Fence Garden Fence Euro Wire Fence,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,Hot Selling Mini 3D Printer 80mm/S Ender-3 PRO Cheap 3D(Hydraulic Fold-Bend Machine Hydraulic Bending Machine, 1996). The soluble protein may have commercial use as gelatines,White and Green Board, School Writing Board, School Furniture (GT-76C), peptides or amino acids production (Current Precise LED Digital Ammeter, 1991;Automatic Drinking Mineral Water Filling Line/Water Bottling Line, 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;Newest Design Factory Price Brown Leather School Bag Genuine Leather Backpack for Men., 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 Polypropylene Two Layer Film Blowing Machine.
