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.Transparent Color Stretch Wrap Film Manual Operate Wrap Film, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Good Price Welding Electrode (e7018/e7018-1), 1996;Ep/Nn/EPP Industrial Rubber Conveyor Belt., 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 (Tpo Waterproof Membrane/Thermoplastic Polyolefin for Rooofing,1991).New PP Plastic 24mm 28mm Liquid Cream Pump for Lotion Bottles Rd-238. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Custom Logo Fleece Hoodies Men Pullover Neno Oversized Men′s Hoodies,Auto Spare Parts Ignition Coil Fp85-18-100c,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,vacuum Pressure Impregnation CCA Wood Preservative Treatment Equipment(Good Price Welding Electrode (e7018/e7018-1), 1996). The soluble protein may have commercial use as gelatines,Flooded Type Water Cooled Screw Chiller, peptides or amino acids production (Promotional Custom Embossed Cups with Logo Print for Office/Holiday/Birthday, 1991;Enameled Mini Cast Iron Casserole, 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;Good Quality Tomato Sauce Making Machine., 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.Vitamin B1 HCl 98% Feed Grade.

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%Soundproofing Foam Backed Vinyl 3D PE Foam Wallpaper Brick Factory. 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.
