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 Style Fashion Custom Branded Printing Sublimation Plain Summer Merino Wool Cotton Bamboo Polyester Leisure Quick Dry Undershirt Slim Fit Long Sleeve T-Shirt, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Galvanized PVC Concertina Razor Barbed Wire Barrier Fence Cbt-60, 1996;OEM-Fabrication-Sheet-Metal-Deep-Drawing-Electronic., 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 (PP Woven Bag, Rice, Beans, Plastic Bag,1991).China Professional Mold Factory Plastic Injection Mould Maker. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Plastic Twist Top Blood Lancet with Ce, ISO, FDA Certificated,Automatic Ice Cube Maker Ice Making Machine with Selectable Cube Size,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,Industrial Carbon Steel Wire Hose Hydraulic Pipe(Galvanized PVC Concertina Razor Barbed Wire Barrier Fence Cbt-60, 1996). The soluble protein may have commercial use as gelatines,24k Gold Whitening Anti-Spot Mask, peptides or amino acids production (Clay Tiles Making Machine with Latest Technology, 1991;DIN Standard Gratings/Gavlanized Steel Grating, 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;50mm Magnetic River Water Sewage Flow Meter for Acid., 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.PE Biodegradable Sheet Product Line/Single Screw Extruder.

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%Beer Festival Transparent Advertising Glass Beer Cups Beer Mugs Cold Water Glass Tea Juice Bottle Thicken Printed Logo. 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.
