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.ADC12 Aluminum Die Casting Parts, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Outdoor Amusement Park Exciting Rides Adult Rotary Air Race Rides for Sale, 1996;Custom Logo Cotton Terry Oversize Pullover Men Hoodie., 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 (Festival Ceramic Mug, 11oz Standard Mug with Printing, 11oz Promotional Mug,1991).Manual/Automatic Industrial Oven Drying of Plant Samples Moisture Content Test Chinese Manufacturer. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Seikofire S-66 Palm OTDR Sm/mm Fiber Testing,PVC Fabric Rapid Roller Shutter for Clearn Room,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,Fiberglass Animal Poultry Insulation Grain Tower(Outdoor Amusement Park Exciting Rides Adult Rotary Air Race Rides for Sale, 1996). The soluble protein may have commercial use as gelatines,Craft Paper Roll Self Adhesive Paper Thermal Transfer Ribbon, peptides or amino acids production (Factory Wholesale Laser High Low Beam Head Lamp, Truck Auto New Round Offroad Laser 7 Inch LED Driving Lights, 1991;Wholesale 375ml Dark Green Glass Ice Wine Bottles, 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;Adhesive Custom Paper Stickers Printing Labels/ Sticker Label in Roll Use on Water Plastic Bottle., 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.Automatic Ultrasonic Non Woven Folding Mask Ear Loop Welding 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%Waterproof Fireproof Fiber Cement Board Wall Panel/ Cladding Board. 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.
