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.22*30mm 12SMD 5050 LED Reading Light for Car, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (SMS 25g Non Woven Isolation Gown with Knitted Cuff for Hospital, 1996;Wholesale 1-40mm PVC Foam Sheet 3mm 5mm 8mm Hot Thickness 35mm Special Thickness., 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 (Outdoor Cheap Portable Stage Aluminum Truss Stage,1991).One Arm Motorized Multifunction Hospital Equipment for China Supply. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Custom Anodized Aluminum Bending Parts Sheet Metal Stamping Parts,P3.91 500X500mm Indoor Portbale Flexible LED Curtain Display,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,Vertical Granule Grain/Peanuts/Seeds/Sugar/Rice Packing Automatic Filling Packaging Machine(SMS 25g Non Woven Isolation Gown with Knitted Cuff for Hospital, 1996). The soluble protein may have commercial use as gelatines,Profile 60X60mm Aluminum Body Pendant Mount LED Ring Light Circular Profile Lighting Fittings, peptides or amino acids production (Metallurgy Rotary Vacuum Drum Filter Equipment From Hengchang machinery, 1991;Printed Wristband Cotton Wristband RFID Woven Wristband, 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;High Quality Wholesale Clear 50ml Flat Square Crimped Glass Bottles., 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.Dolphin Designed Handheld Massager (LC-889).
