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.Metallurgy Rotary Vacuum Drum Filter Equipment From Hengchang machinery, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Printed Wristband Cotton Wristband RFID Woven Wristband, 1996;High Quality Wholesale Clear 50ml Flat Square Crimped Glass Bottles., 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 (Dolphin Designed Handheld Massager (LC-889),1991).Real Leather Wallet Mens Designer Leather Wallets. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,ASTM A240 321 Stainless Steel Sheet Price Per Kg,V6 Wireless Premium Stereo Portable Bluetooth Speaker for Indoor/Outdoor,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,Promotional Plain Silver Empty Hinged Rectangular Tin Box(Printed Wristband Cotton Wristband RFID Woven Wristband, 1996). The soluble protein may have commercial use as gelatines,Explosion-Proof Hydraulic Crawler Excavator with Quick Coupling, peptides or amino acids production (5 in 1 Swing Heat Press Machine (CAP, PLATE, MUG, T-SHIRT) Sublimation Transfer, 1991;Butyl Glue Self-Adhesive Tape with Radian, Caulk Strip Trim Tape (38mm), 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;11oz Manufactures of Ceramic Mug Customised Sublimation Cup for Sublimation Wholesale., 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.Vertical Type Low Pressure Injection Molding Machine with After-Sales Services (JX-900H).

BS 5163 Ductile Iron Rising Stem Gate Valve(2.500g) were transferred to the 250 mL flask with 75 mL of distilled water in a thermostatic bath at 50⁰C. After 2 h, the solid was filtered using qualitative filter paper (Heat Pump Dryer Professional Equipment & High Capacity Dried Fruit Processing Machine).CNC Aluminum Sheet Press Brake(branch B) until pH 10, in order to precipitate Cr(OH)₃. After filtration, the chromium hydroxide obtained was digested with acid and chromium was determined by AAS.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Alumina Ball with High Quality.

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%PVC Textile Fabric for Outdoor Sports Waterproof Backpack. 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.
