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.New Style Polyester Duffle Bag for Travelling Trolley Bag Luggage Bag with 2 Wheels, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Good Day HOWO 4X2 5000liters 6000liters LPG Dispenser Truck, 1996;Dedi Manufacture Self Service SIM Card Dispenser Kiosk Machine with Cash Dispensing Module., 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 (ADSS Newest Ultra Therapy Skin Tightening 3D Hifu,1991).Cross Belt Magnetic Separator Super Strong Neodymium Permanent Magnet to Remove Iron Scrap. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Paper Straw White Custom Panama Chapeau Men′s Sombrero Fedora Hat with Ribbon,High Quality Ceramic Chrome Hybrid Bearing Oil,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,Medical Product Nonwoven Disposable Surgical Gown PP Isolation Gown(Good Day HOWO 4X2 5000liters 6000liters LPG Dispenser Truck, 1996). The soluble protein may have commercial use as gelatines,CAS No: 1317-80-2 Anatase Rutile TiO2 Titanium Dioxide Powder, peptides or amino acids production (Digger Arm Small Wheel Loader (HQ908) with CE, 1991;15ml 18ml Glass Fish Model Perfume Bottle with Plastic Sprayer, 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;Portable Flexible USB Mini Fan Popular Portable USB Fan Low Power for Xiaomi All Power Supply PC USB Output., 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.Water Based Emulsion Paint Production Line.
