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.White Marble, Carrara White, Bianco Carrara Marble for Sale, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Upper Limbs Machine/Spare Parts for Fitness Equipment, 1996;Cvkr Silent Check Valve Dn350., 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 (Best Shatterproof Gold Rim Wine Glasses,1991).10inch Schedule 40 Carbon Steel ERW Pipe Casing for Water/Well with Black Painting. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Quality Disposable Barbecue BBQ Mesh Grill Netting Mesh for Korea,Leather Wallet Slim Front Pocket Wallet Billfold ID Window RFID Blocking,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,Relleno De Acido Hialuronico Con Enlace Cruzado Zenfil(Upper Limbs Machine/Spare Parts for Fitness Equipment, 1996). The soluble protein may have commercial use as gelatines,20inch Aluminum Folding Bike Pedal Assit Electric Bike with Throttle, peptides or amino acids production (Chinese Color Steel Glazed Tile Purlin Roll Forming Machine, 1991;Industrial Sausage Meat Smoker Oven/Smokerhouse Oven, 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;Men′s High Quality Mercerised Cotton Business Dress Socks., 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.Livining Room Rugs Geometric Patterns Carpets 6′*9′.
