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.Full-Auto CNC Cutting Machine for Architecture Glass Sheet, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Oring O-Ring All Kinds of Rubber Material NBR Nr EPDM Rubber Product, 1996;Hot Forming Pushing Elbow Making Machine., 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 (13 Inch Pneumatic Rubber Wheel Bicycle Wheel with Plastic Rim for Kids Balance Bike,1991).Professional Inkjet Printer Ultrasonic Printhead Cleaning Machine for Epson Dx5 Dx7 Seiko 510 Konica 512 Polaris Xaar Spectra UV/Solvent Print Head Cleaner. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,As568 Standard Brown FKM Rubber O Ring for Sealing,The Chinese Factory Directly Supply Low Price High Quality Washing Powder Laundry Detergent,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,Hot Sale Beautiful RFID NFC Ntag213 Epoxy Card(Oring O-Ring All Kinds of Rubber Material NBR Nr EPDM Rubber Product, 1996). The soluble protein may have commercial use as gelatines,200W UFO LED High Bay Light Fixture for Interior Exterior Applications, peptides or amino acids production (China OEM Manufacturers Supply 8 Person Golf Cart (DG-C6+2), 1991;13.4L 22.4L Inflatable Helium Tank Disposable Balloon Helium Gas Cylinder, 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;Bathroom False Plastic Board Interior Decorative 3D Wall Panels., 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.Mushroom Head Stud Sert.

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%10 Gauge Galvanized Welded Wire Mesh for Construction Using. 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.
