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.Latest Solid Fuel Lightweight Folding Stoves Outdoor BBQ Portable Wood Stove with Mesh Stainless Steel Backpack Camping Stove, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Food Grade 40ml 100ml Pudding Glass Bottle Mini Milk Bottle with Cork or Cap, 1996;Fire Alarm Detector 24VDC Reflective Beam Detector., 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 Cosmetic Refillable Plastic Perfume Spray Bottle,1991).Automatic Mini Bag Spices Small Salt Packing Packaging Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,No 55 Steel Wire Cross Type Razor Barbed Wire,4V330-10 Air Compressor Solenoid Industrial Valve,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,Professional Various Standard Hot Sale Rotary Lab Single Round Punch(Food Grade 40ml 100ml Pudding Glass Bottle Mini Milk Bottle with Cork or Cap, 1996). The soluble protein may have commercial use as gelatines,Metal Powder Cooler Heat Exchanger Fluid Bed Drying Equipment Substitute, peptides or amino acids production (Light Blue Color Glass Drink Bottle for Beer, 1991;Outdoor Waterproof Portable Socket Box Electrical Combined Socket Power Distribution Box, 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;IP65 Degree Quality Circular Screen Machine Use Vertical Electrical Motor., 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 Linear 5 Gallon Barrel Bottle Water Filling Machine.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Screw/Countersunk Head Screw 6 Ribs with Wing, Csk Wing Screw,.

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%Cleanroom White PVC Dotted Anti-Static Gloves. 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.
