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.Good Quality 3.8 6 8 Inch Resistant Rubber Tire Dog Chew Toy with Handle Rope for Pets, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Rainbow Metallized Polyester / Holographic Embossing Metallized Pet Film, 1996;8W IP65 CCT Changeable Dimmable Fire Rated LED Downlight Bezel Interchangeable Fireproof Down Light., 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 Price 0.5ml 1.0ml Ceramic Wickless Vape Cartridge Liberty V9,1991).Powder/Spices Powder Packing Machine with Four/Three Side Seal. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Black Phosphated Bugle Head Csk Head Drywall Screw,Liquid Detergent, Shampoo Mascara Titling Mixing and Emulsifying Making Machine,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,China Safety Long Boom Mini Excavator Track Chain Hydraulic Pump(Rainbow Metallized Polyester / Holographic Embossing Metallized Pet Film, 1996). The soluble protein may have commercial use as gelatines,Cbt-65 Type Hot Dipped Galvanized Concertina Razor Barbed Wire for Fence, peptides or amino acids production (6 Inch Plastic Breathing Cap for The IBC Valve, 1991;Efficiency High Precision PT52y-X Turning Milling CNC Machine for High Quality and Reliability, 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;Washami Wholesale 2 in 1 Custom Fashion Lip Gloss Packaging., 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.Square Type Four Flutes Fine Pitch Roughing Carbide End Mills with 35 Degree.
