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.10ton Telescopic Hydraulic Truck Crane, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Phantom Moving Head Laser Light/New Stage Effect Light for Disco, Bar, KTV, 1996;for iPhone 6 LCD 100% Brand New with Touch Screen Digitizer Assembly Replacement Display., 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 (Cracker Multi Rows Trayless Packaging Machine,1991).Galvanized Wire Mesh Fence/Cattle Deer Fence Supplier From China. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2 Quick Change Flexible Roloc Disc,UTP Cat5e Folding Type 90 Degree Tooless RJ45 Keystone Jack,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,High Quality Aluminium Windows Thermal Break China Supplier(Phantom Moving Head Laser Light/New Stage Effect Light for Disco, Bar, KTV, 1996). The soluble protein may have commercial use as gelatines,Farm Machine Parts Spring Harrow Tines/ Fork Tedder Tines, peptides or amino acids production (2.0mm Pitch Pin Header SMT Type T Series Single Row Dual Housing B01, 1991;PRO-Installer Fiber Optic Termination Kit Lk-6016, 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;Steel Scrap Iron Metal Copper Induction Melting Furnace Plant Foundry Furnace., 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.Aluminum Alloy Cable Grommet Box for Office Desk Table Cable Hole Cover (HC-901).

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%Comfortable Two Piece Women Fitness Clothing for Gym Wear. 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.
