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.FRP Water Tank GRP Fishing Tanks From Factory Supply, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Decorative House Stone Coated Metal Roof Tile, 1996;Integrated Crawler Rotary Underground Fully Hydraulic Tunnel Jumbo Drilling Rig., 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 (6LTR Stainless Steel Foam Empty Fire Extinguisher Cylinder,1991).Laser Marker Animal Ear Tag Optical Fiber Laser Marking Machine System. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Sachets Powder Coffee Stick Powder Bag Salt Packaging Packing Machine,PPE-Plus En140 Gas Respirator Filter Custom Safety Gas Mask for Military Use,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,Blue Steel Packing Strip(Decorative House Stone Coated Metal Roof Tile, 1996). The soluble protein may have commercial use as gelatines,High Quality Powder and Wax Brush with Wooden Handle, peptides or amino acids production (Cheap Price Paper Straws Individually Wrapped Drinking Straw, 1991;ASTM 304 304L Stainless Steel Sheet with Best Prices and High Quality, 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;Hot Sale Wood Grain Decorative Paper for Laminated Door/ Melamine Paper for MDF., 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.Flexible Polyurethane Tube PU Spring Coil Hose Pneumatic Colorful Spiral Hose.

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%Factory Sell P7.8 Transparent LED Display Screen. 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.
