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.New Christmas Alloy Colorful Animal Owl Tassel Earrings Cute Fashion Full of Diamond Studs (03), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (China Supplier Building Construction Steel Frame (ZY431), 1996;iPhone Xr Sublimation Blank 2D PC Phone Case/Cover for Heat Transfer Printing., 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 (Lab Equipment portable Fume Hood,1991).Fashion Kid Wear Long Sleeve Boy Y/D Stripe T-Shirt. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,10ton Telescopic Hydraulic Truck Crane,Phantom Moving Head Laser Light/New Stage Effect Light for Disco, Bar, KTV,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,for iPhone 6 LCD 100% Brand New with Touch Screen Digitizer Assembly Replacement Display(China Supplier Building Construction Steel Frame (ZY431), 1996). The soluble protein may have commercial use as gelatines,Cracker Multi Rows Trayless Packaging Machine, peptides or amino acids production (Galvanized Wire Mesh Fence/Cattle Deer Fence Supplier From China, 1991;2 Quick Change Flexible Roloc Disc, 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;UTP Cat5e Folding Type 90 Degree Tooless RJ45 Keystone Jack., 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.High Quality Aluminium Windows Thermal Break China Supplier.

Nylon Cable Glands with CE(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 (Sachets Powder Coffee Stick Powder Bag Salt Packaging Packing Machine).X Shaped Extruded Aluminum Window Screen Frames(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.

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%Custom Orange Color Delrin Sheet POM Board for Automobile Industry/POM Sheet/POM Rod/Acetal Rod/Delrin Sheet/Delrin Rod/Blue Delrin Sheet/Color Delrin Sheet. 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.
