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.2inch Fire Gasoline Pump with Fire Hose and Follow Nozzle, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (304 &314 Stainless Steel Seamless Bending Tube, 1996;Class One UV Laser Marking Machine for Jade Stone Ceramic Logo Mark., 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 (Custom Grey Full-Zip Cotton Mens Hoodies,1991).Top Open Room Safe Box with LCD Display for Hotel 15-Inch Notebook. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,7inch Industrial Tablet Computer Naked Resistance Touch Screen,Glass Door Passenger Sightseeing Elevator for Sale,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,Efan Custom Made Promotional Plastic Mould for American Cartoon Keychain, Gift, Plastic Toys(304 &314 Stainless Steel Seamless Bending Tube, 1996). The soluble protein may have commercial use as gelatines,12V 24V 5rpm 30rpm 100rpm 2n. M High Torque Worm Gear DC Motor, peptides or amino acids production (Hydraulic Adapter and Connections for High Pressure Hose Hydraulic Fittings Double Pipe Nipple, 1991;Industrial Grade General Purpose Titanium Dioxide Rutile/Anatase, 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;Fcy30 Transport Mini Tipping Dumper., 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.Ptj601 Model 4 Post Storage Cars Parking Elevator for Auto Park.
