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.Fused Silica Quartz Lump 5-50mm for Refractory Materials, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cold Drawn D2 H13 Alloy Steel Turning Roll, 1996;Interlocking Anti-Fatigue Kitchen Rubber Mat, Kitchen Floor Mat., 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 (Bread Box Bamboo Large Capacity Roll Top Bread Holder Cupcake Storage Food Bin for Loaf Pastry Snacks,1991).High Quality Suitcase Frame or Profile Bending Machine with Ce Aprroved. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Colorful 100LED Copper String Light Outdoor LED,H365 Emas Chainsaw Spares Cylinder Kits,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,PP Woven Bag for Feed, Rice, Corn Feed Bag Rice Bag 10, 25, 50 Kg(Cold Drawn D2 H13 Alloy Steel Turning Roll, 1996). The soluble protein may have commercial use as gelatines,A4 Diploma Covers Wholesale with Silver Foil, peptides or amino acids production (OEM Activewear Dry Fit Custom Printed Yoga Wear Wholesale Sexy Fitness Gym Sports Yoga Leggings, 1991;Adjustable UV Protection Brim Plain Snapback Transparent Baseball Cap, 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;120L 240L Oil Universal Chemical Spil Absorbent Kits., 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 Prints PU Small Cute Summer Edition Girls′ Kiss Lock Coin Purse.

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%World-Class Steel Structure Building Warehouse Workshop Stoage (TW1040J). 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.
