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.Yet905 Wireless Keypad Doorbell Kits with Remote Control, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hotel Safe with Digital Keypad and Mechanical Key (ELE-SA200FR), 1996;Original Sinotruk HOWO Truck Parts - Exhaust Pipe Wg9725542042., 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 (China Factory Queen Mattress with Visco Memory Foam and Latex,1991).Multi-Port Ss 304 Manual Three Way Non-Retention Ball Valve. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Convenient Operation Hard-Wearing Smooth Feeding Biodegradable Bagasse Pulp Tableware Plate Making Machine/Former/Maker,HD Night Vision IR Laser Camera with PTZ for 1200m Surveillance,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,Ceiling Mounted IV Stand Stainlesss Steel I V Pole(Hotel Safe with Digital Keypad and Mechanical Key (ELE-SA200FR), 1996). The soluble protein may have commercial use as gelatines,Pipe Connection Types of Pressing Scaffolding Universal Clamp, peptides or amino acids production (Ml33-2mm Eddy Current Linear Position/Displacement Sensor, 1991;Veterinarian Ultrasound Diagnostic System for Cow, Horse, Swine, Goat, 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;Wholesale 25kg 50kg White PP Woven Sack for Flour Feed Grain., 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.Wholesale Long Lasting Custom Private Label Glitter Lip Gloss.
