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.Single Core Solid Copper Conductor Rg Coaxial Cable, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Mie Kang 40 Watts Electric Mosquito Bug Zapper for Residential and Commercial Use, 1996;Turnkey Colour Cladding Commercial Use Prefabricated Steel Structure Building., 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 (Baby Clothes Wear Fleece Baby Bunting Onesie Jacket,1991).Life Size 170cm Silicone Sex Dolls Real Love Doll for Male. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Reflective Sheeting Material for Licence Plate,Industrial Grade Nitrous Oxide for Hot Sales,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,Latest Solid Fuel Lightweight Folding Stoves Outdoor BBQ Portable Wood Stove with Mesh Stainless Steel Backpack Camping Stove(Mie Kang 40 Watts Electric Mosquito Bug Zapper for Residential and Commercial Use, 1996). The soluble protein may have commercial use as gelatines,Food Grade 40ml 100ml Pudding Glass Bottle Mini Milk Bottle with Cork or Cap, peptides or amino acids production (Fire Alarm Detector 24VDC Reflective Beam Detector, 1991;Wholesale Cosmetic Refillable Plastic Perfume Spray Bottle, 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;Automatic Mini Bag Spices Small Salt Packing Packaging Machine., 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.No 55 Steel Wire Cross Type Razor Barbed Wire.

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%Hot Sell with 12 Sets Hose Crimping Tool 220V 4-51mm with Big Discount. 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.
