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.Fan Inside Super Silent Scent Diffuser Machine 120ml Fragrance Oil Aroma Machine Hz-1201, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Heater Blower Motor Fan Switch for VW Santana 32b Lt Polo Coupe Transporter IV Golf I Jetta Audi 80 90 B2 191959511A 321959511A, 1996;Stainless Steel Whisky Chilling Stones., 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 (Nmsafety TPR Back Cut Resistant Oil and Gas Impact Work Glove,1991).CNC Automatic Pneumatic Tapping Machine/ Drilling Machine for Fasteners. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Automatic 150m/Min Multi Color Uesd Motor Roto Gravure Rotogravure Printing,Good Quality Custom Car Power Window Cable for Ford Car,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,Solar Panel PV System Mc4 Circular Connector(Heater Blower Motor Fan Switch for VW Santana 32b Lt Polo Coupe Transporter IV Golf I Jetta Audi 80 90 B2 191959511A 321959511A, 1996). The soluble protein may have commercial use as gelatines,1.5 Ton 15 Kn 3300 Lbs Hydraulic Winch for Lifting and Pulling, peptides or amino acids production (Hot DIP Galvanized Sewer Cover --Professional Grating Manufacturer, 1991;Industrial Pouring Ladle Steel Furnace Casting Ladle for Casting, 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;Boiler Fin Tube, Hot Steam Ot Water Cooling ASME SA179 SA192 Fin Tube Wall., 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.Plastic Recycling Centrifugal Dewatering Machine.
