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.Custom Grey Full-Zip Cotton Mens Hoodies, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Top Open Room Safe Box with LCD Display for Hotel 15-Inch Notebook, 1996;7inch Industrial Tablet Computer Naked Resistance Touch Screen., 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 (Glass Door Passenger Sightseeing Elevator for Sale,1991).Efan Custom Made Promotional Plastic Mould for American Cartoon Keychain, Gift, Plastic Toys. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,12V 24V 5rpm 30rpm 100rpm 2n. M High Torque Worm Gear DC Motor,Hydraulic Adapter and Connections for High Pressure Hose Hydraulic Fittings Double Pipe Nipple,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,Industrial Grade General Purpose Titanium Dioxide Rutile/Anatase(Top Open Room Safe Box with LCD Display for Hotel 15-Inch Notebook, 1996). The soluble protein may have commercial use as gelatines,Fcy30 Transport Mini Tipping Dumper, peptides or amino acids production (Ptj601 Model 4 Post Storage Cars Parking Elevator for Auto Park, 1991;Hot Sale High Quality Candy/Food/Cake/Soap Pillow Packing Machine (BS-250), 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;Premium Grade Rubber Cloth Duct Tape., 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.Sud1000h Poly Welder Butt Fusion Machine.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%High Aluminum Insulating Ceramic Fiber Paper for Industrial Kilns. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V₀) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
