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.Electrial Galvanized Conduit Box/Gi Pipe Fitting, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wholesale Eco Friendly Food Grade High Quality Glass Football Mason Jar, 1996;High quality Brass Forged Gate Valve with Casting Iron Handle., 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 (Aluminum Lighting Flashlights Zoomable Rechargeable LED Tactical Flashlight Torch (SYSG-180820),1991).High Lumen 150W 200W LED High Bay Lighting High Bay LED Light Fixture. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Cog Mono Round Display LCD Module,TV Stand Carving European LED Lights Heating Fireplace (320SS),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,High Quality Mini LED Flood Light SMD Flood Light 150W(Wholesale Eco Friendly Food Grade High Quality Glass Football Mason Jar, 1996). The soluble protein may have commercial use as gelatines,Low Price Fashion Unique Plastic Zipper, peptides or amino acids production (Silica Gel- Indicating Blue to Pink After Adsorption, 1991;Offer High Quality Square and Round Cast Iron Manhole Cover, 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;White Tight Long Sleeves off Shoulders Celebration Bandage Dress., 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.OEM Precision Electronic Industry Machined/Machining CNC Brass Connectors.

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%Dubai Products Rectified Tile for Wall. 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.
