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.Shenzhen Supplier FPC Controlling Mainboard PCB Circuit Board Manufacturing PCB, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (OEM Design Fashion Women Nylon Backpack High Quality Backpacks Custom Backpack, 1996;Wholesale Magic Barber Personal Use Cordless Rechargeable LCD Hair Clipper., 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 (Venlo Type Agriculture Hydroponic Glass Greenhouse for Vegetables/Flowers/Tomato/Farm/Garden,1991).100% PVC Resin PVC Clear Transparent Film for Shower Curtain. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Hotel Security Improvement Zinc Alloy Door Chain,Anti-Pollution Type 160kn Insulator Porclelain Disc,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,Nickel 200 Floating Ball Valve(OEM Design Fashion Women Nylon Backpack High Quality Backpacks Custom Backpack, 1996). The soluble protein may have commercial use as gelatines,3-Layer PE Coating Production Line, peptides or amino acids production (Multi Functional Two-Layer Woven Leather Jewelry Box Organizer Suitcase, 1991;Surgical Instrument! ! Endoscopic Grasping Forceps for Australia Endoscopy, 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;Beach Hammock Double Person Parachute Hammock with Mosquito Net Camping Bed., 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.Wooden Queen/King Size Japan Sofa Bed G1162.

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%10mm AISI304 Carbon Steel Balls Motor Bearing for Slide. 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.
