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.Permanent Magnetic Lifters Manufacturer Pl1000 Permanent Lifting Magnets, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (LED Lighted Vanity Makeup Mirror with Built-in 800mAh Battery and USB Charging, Natural Daylight, Dimmable, Foldable Esg10310, 1996;Self Balancing Scooter 2 Wheel Electric Standing Balance Scooter Skateboard Hoverboard with Remote Key., 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 (Eko Custom Color Marked Self-Adhesive Hook and Loop Cable Tie for Wire Management,1991).High Quality CO2 Laser Marking Machine with Ce. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,New Design Inclined Plane 18W LED Wall Washer Lighting,2ton R Type Electric Wire Rope Hoist with Single Speed,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,Stainless Steel Body Infrared Burner Good Selling Gas Stove(LED Lighted Vanity Makeup Mirror with Built-in 800mAh Battery and USB Charging, Natural Daylight, Dimmable, Foldable Esg10310, 1996). The soluble protein may have commercial use as gelatines,High Crush Strength Activated Alumina as Petrochemical Catalyst Carrier, peptides or amino acids production (Adhesive CAS 9003-35-4 Phenolic Resin, 1991;Household Kitchen Cleaning Tools Aluminum Handle Cotton Dust Control Mop, 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;Manufacture Best Choice Liquid Flocculant for Ink Removal., 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.Hot Dipped Galvanized Oval Wire Brazil.
