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.Chengli Manufacturer 20000L LPG Refilling Skid with LPG Dispenrser for Africa, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Modern Carbon Fiber Bathroom Vanity Combo with Mirror Cabinet, 1996;Multifunctional Stainless Steel Mesh Filter Cylinder Punched Round Hole Shape Filter Tube., 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 (Condoms/Sex Toys/Capsule Toy Vending Machine,1991).Abstract Decorative Oil Wall Paintings on Ultra Clear Low Iron Glass (MR-YB6-2046B). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Best and Most Safety Lancet (Control Puncture Depth) , Highly Stable Performance Disposable Blood Lancet with Cheap Price,Outdoor Type 40kgs Movable Ice Maker for Store Use,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,Motorcycle Accessories with MIM Part by Metal Injection Molding Technology with Precision and Complex Metal Parts(Modern Carbon Fiber Bathroom Vanity Combo with Mirror Cabinet, 1996). The soluble protein may have commercial use as gelatines,Electric 100W Three Wheels Toy Car for Sale, peptides or amino acids production (2*2 4G Lte MIMO Antenna Rrouter/CPE, 1991;2.4G WiFi Wireless Video Baby Monitor Camera 3.2inch (3.2′′), 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;Electric Galvanized Coated Barbed Wire (MT-BW013)., 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.Lost Wax Casting Precision Casting Spring Snap Hooks for Chain Rigging.

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 Selling Galvanized Bolt for Fixing Cable Clamp on The Pole. 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.
