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.20 Watt AC Power Insect Killer Lamp Trap UV Light Electronic Bug Zapper Factory, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hot Sale Laser Projector RGB Laser Light for Stage, 1996;Pop up Tent Garden Outdoor Folding Gazebo with Mosquito Net., 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 (Chrome Multi-Arc Vacuum Planting Door Hinge PVD Coating Machine Manufacturer,1991).Acm Dewatering Twin Screw Extruder. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Telescopic Zoom Outdoor Tactical LED Flashlight (SYSG-180820),Tumble Belt Type Shot Blasting Machine for Iron Castings Parts,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,Bsp Standard Malleable Iron Pipe Fitting Hexagon Nipple(Hot Sale Laser Projector RGB Laser Light for Stage, 1996). The soluble protein may have commercial use as gelatines,Good Quality Good Price China Plastic Injection Molding Machine, peptides or amino acids production (Pet Hair Remover Glove for Dog, Grooming Gloves Brush, 1991;Modern Living Room Furniture Hotel Bedroom Custom Corner Sofa, 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;Alumina Balls for Hydogen Peroxide., 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.Anti-High Pressure Insulated Pliers with PVC Dipped Handles.

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%Cherry Wooden Grain PVC Film in Furniture. 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.
