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.Mini Hydraulic Adjustable Gas Spring Strut for Furniture Cabinet, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Afraic Market Mobile Food Vending Cart, 1996;Tealight Candle Holder Wholesale Round Glass Candle Holder Bulk Glass Votive Candle Holders., 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 (Double Wall Glass Coffee Mug Tea Cups,1991).Diameter38mm Food Grade Rubber Hose for Beer Equipment Cleaning. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,30g Frosted Glass Jar with Bamboo Lid Empty Cream Jars for Skin Care,Vibrating Condom Ring and Cock Ring Supplier,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,Full Color Print Glossy Laminated PP Woven Shopping Gift Bag(Afraic Market Mobile Food Vending Cart, 1996). The soluble protein may have commercial use as gelatines,High Quality 10 Inch Carbon Seamless Steel Pipe Schedule 40, peptides or amino acids production (Quality Assurance Advanced Design Microfiber Filling Washable Pillow, 1991;Sauer 90R180 90M180 Hydraulic Piston Pump Parts with Best Price, 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;Decorative Waterproof Fireproof Heat Resistant HPL High Pressure Compact Phenolic Laminate Board., 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.Wall Mounting Metal Control Box Control Desk.

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%Big Sale Hot Feature Home Crystal Mini Red Wine Vodka Cup Shot Glass. 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.
