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.CNC Grinding Machining Parts High Precision, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Cheap Price Disposable IV Infusion Set with Precise Filter, 1996;Clear Drug Packaging Custom Printed Recloseable Medicine Plastic Bag., 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 (GB11638 10L 40L C2h2 Low Pressure Acetylene Cylinder with Valve,1991).Disposable Clear Take Away Plastic Salad Bowl Forming Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Blank PVC Card 13.56MHz/ 125kHz Contactless Smart Card for Access Control,Agricultural Cover/Crop Protection Anti-UV PP Spunbond Nonowven Fabric, SBPP,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,Eco-Friendly Acoustic Panel PU Sponge for Sound Absorbing Noise Sponge(High Quality Cheap Price Disposable IV Infusion Set with Precise Filter, 1996). The soluble protein may have commercial use as gelatines,Carbon Stee Semless Pipe (ASTM A106 Gr B), peptides or amino acids production (OEM Wld8200 Infrared Lamp Spray Paint Booth China Supplier for Sale, 1991;Yutong Bus Parts Ceiling Diffuser Vent Air Louver Vent Air Diffuser Vent Air Diffuser Ceiling Vent Slot Diffuser Vent, 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;Hot Selling House Floor Cleaning 360 Spin Mop., 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.Srfloor Plastic Flooring Interlock Suspended Outdoor PP Tiles.

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%Explosion Proof Rechargeable LED Searchlight. 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.
