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.Chrome Multi-Arc Vacuum Planting Door Hinge PVD Coating Machine Manufacturer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Acm Dewatering Twin Screw Extruder, 1996;Telescopic Zoom Outdoor Tactical LED Flashlight (SYSG-180820)., 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 (Tumble Belt Type Shot Blasting Machine for Iron Castings Parts,1991).Bsp Standard Malleable Iron Pipe Fitting Hexagon Nipple. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Good Quality Good Price China Plastic Injection Molding Machine,Pet Hair Remover Glove for Dog, Grooming Gloves Brush,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,Modern Living Room Furniture Hotel Bedroom Custom Corner Sofa(Acm Dewatering Twin Screw Extruder, 1996). The soluble protein may have commercial use as gelatines,Alumina Balls for Hydogen Peroxide, peptides or amino acids production (Anti-High Pressure Insulated Pliers with PVC Dipped Handles, 1991;Hot Selling Electronical Blue Pet Plastic Release Film Price, 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;DIN127 Stainless Steel Spring Lock Washer., 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.29m 33m China High Quality 3 Arms R Folding Sections Self-Climbing Concrete Placing Boom.

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%Hot Selling Extruded Aluminum Window Frame and Sliding Door Profile for Curtain Wall (A44). 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.
