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.PLC Control Aluminum Tin Can Filling Sealing Machine/Line/Equipment/Canning Machine for Beer and Soda, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Stainless Steel Main Pipe Tee Joint for Railway Piping System, 1996;Automatic Thermoforming Making Machine for Plastic Egg/Battery/Fruit/Cake/Fast-Food Tray Container., 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 Promotion Snack Children School Lunch Bag Cooler Bag,1991).Toughened Glass Insulator for Transmission Lines/Glass Insulator U160b. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Full Automatic Paper Lunch Food Box Carton Forming Machine,Single Core Solid Copper Conductor Rg Coaxial Cable,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,Mie Kang 40 Watts Electric Mosquito Bug Zapper for Residential and Commercial Use(Stainless Steel Main Pipe Tee Joint for Railway Piping System, 1996). The soluble protein may have commercial use as gelatines,Turnkey Colour Cladding Commercial Use Prefabricated Steel Structure Building, peptides or amino acids production (Baby Clothes Wear Fleece Baby Bunting Onesie Jacket, 1991;Life Size 170cm Silicone Sex Dolls Real Love Doll for Male, 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;Reflective Sheeting Material for Licence Plate., 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.Industrial Grade Nitrous Oxide for Hot Sales.
