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.Portable Mini USB Charging Flashlight 10W T6 LED Flashlight (SYSG-190321), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Brushed Cotton Twill Fine 3D Embroidery Custom Baseball Cap, 1996;Robotic Fastening Tool/Desktop 4-Axis Screw Fastening Robot  /Instead of Manual Fastening., 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 (Wholesale Logo Printed Recycled Retail Paper Shopping Bag with Handle,1991).Black Plastic Drain Pipe Underground Direct Factory Price HDPE Pipe for Water Supply Large Diameter Plastic Pipe. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Stainless Steel Coil Heat Exchanger Industrial Water Cooler Stainless Steel Heat Exchanger,Stainless Steel SS304 SS316L Sanitary Hygienic Air Vent 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,Q35y-30 Ironworker Shearing and Punching Machine Ce Approved Q35y Hydraulic Iron(Brushed Cotton Twill Fine 3D Embroidery Custom Baseball Cap, 1996). The soluble protein may have commercial use as gelatines,Shenzhen Yizexin Numeric Keyboard Conductive Ink Membrane Switch, peptides or amino acids production (High-Tenacity Conveyor Belt/ Steel Cord Conveyor Belt, 1991;Hanwha SMT Chip Shooter LED Pick and Place 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;ACP Aluminium Cmposite Panel Cladding Extrusions., 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.New Model Hydraulic Energy-Saving Disposable Paper Plates/Tray/Coaster Forming Making Machine.
