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.Strong and Comfortable Flexible Wave Back Chair for Banquet (HM-S8), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Telescopic Handle Easy Cleaning Double Sides Chenille & Microfiber Flat Mop, 1996;Patent LED Tri-Proof light Fixture 30W, 3FT 3000lm IP66 Approved., 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 (Single Screw Extruder for Plastic PP/PE Pipe Production Line,1991).Packing 50ml Refill Reed Diffuser Glass Bottle with Silver Screw Neck. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Dog Hook Spring Snap Hook Swivel Eye Bolt Snap Hook Key Hook Alloy Hook Swivel Hook Metal Hook for Handbag Luggage,Gold Star Square Glass Candle Holder for Wedding Decoration,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,11kg 24L Low Pressure LPG Gas Cylinder(Telescopic Handle Easy Cleaning Double Sides Chenille & Microfiber Flat Mop, 1996). The soluble protein may have commercial use as gelatines,Commercial Use Click Lock Standard Spc Vinyl Plank Flooring, peptides or amino acids production (Customized Fashion Luxury Wooden Cosmetic Store Fixture for Shop, 1991;High Pressure Qsl8.9 Injector Fuel Supply Tube for Dongfeng, 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;Precision Customized OEM Auto Hardware Lathe CNC Machining Parts., 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.White Color Enamel Bowls with High Quality.

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%Pneumatic Electric Manual Stainless Steel Sanitary Butterfly Valve. 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.
