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.Cheap Price Roof Wall PU Sandwich Panel Press, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Eco-Friendly Sun-Proof Black Metallic Thread with Beautiful Luster for Dress Use, 1996;industrial aluminum foil roll 8011 8079 1235., 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 (Hospital ICU Portable Electric Injection Syringe Pump Ce ISO Approval,1991).High Flex Mdr 26 to SDR 26 Power Over Cable with Thumbscrews Locking and PVC Jacket. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Mini Hydraulic Adjustable Gas Spring Strut for Furniture Cabinet,Afraic Market Mobile Food Vending Cart,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,Tealight Candle Holder Wholesale Round Glass Candle Holder Bulk Glass Votive Candle Holders(Eco-Friendly Sun-Proof Black Metallic Thread with Beautiful Luster for Dress Use, 1996). The soluble protein may have commercial use as gelatines,Double Wall Glass Coffee Mug Tea Cups, peptides or amino acids production (Diameter38mm Food Grade Rubber Hose for Beer Equipment Cleaning, 1991;30g Frosted Glass Jar with Bamboo Lid Empty Cream Jars for Skin Care, 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;Vibrating Condom Ring and Cock Ring Supplier., 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.Full Color Print Glossy Laminated PP Woven Shopping Gift Bag.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Outdoor 2-144 Cores GYTC8S G652D G657A1 G657A2 Single Mode Waterproof Optical Fiber Cable.

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%High Quality Industrial Grade Anhydrous Sodium Sulfate. 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.
