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.China LCD Display Manufacturer Cjtouch 21.5′′ Capacitive Touch Screen Display, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Various Sublimation Blank Home Supply Fabric Bath Towel etc, 1996;High Pressure 2 1/2 Hose Crimper Machine From Kangmai Hydraulic., 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 (Endoscopic Multi-Band Ligator for Esophageal Varices of Medical Instruments,1991).Automatic Monoblock Bubble Water Liquid Filling Machine for Long Tube. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Best Quality Bending Metal Mould with All Kinds Metal Materials,New Arrivals Lattice Pattern Retro Phone Case for iPhone 6 6s 7 Plus,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,Milling Precision Stainless Steel CNC Machinery Parts(Various Sublimation Blank Home Supply Fabric Bath Towel etc, 1996). The soluble protein may have commercial use as gelatines,U Shape Nails Door Shape Nails Manual Code Naisl Pneumatic Code Nails, peptides or amino acids production (Good Price Stand-up Zipper Doy Pouch Filling Packing Machine, 1991;Seamless Aluminum Tube, Extruded Alloy Aluminum Tube 1060 1070 3A21, 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;Medical Waste Disposal with Microwave Disinfection Equipment Biomedical Infectious Waste 10., 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.360 Degree 3D Vr Panorama WiFi Bulb Camera (PST-VR20B1).
