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.China Manufacturer Cheap Custom High Precision Spiral Compression Phone Clock Stationery Small Torsion Mechanical Metal Micro Pressure Spring, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (300ml Clear Hot Water Packing Glass Bottle with Plastic Cap and Silicon Sleeve, 1996;Plastic Injection Molding Companies China for Tablet PC Case., 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 (27PCS Oscillating Multi Tool Blades Set for Multi-Purpose Tools,1991).High Quality Solid Tungsten Carbide Rods. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Galvanized Steel Overhead Highway Signage Platforms Grating Trench Cover,Sintered NdFeB Ring Magnets for Various Loudspeakers with RoHS Approved,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 Tensisle Strength Tissue Paper(300ml Clear Hot Water Packing Glass Bottle with Plastic Cap and Silicon Sleeve, 1996). The soluble protein may have commercial use as gelatines,Tractor Mounted Beach Cleaning Equipment Large Size, peptides or amino acids production (100gr Perfume Quality Underwear Laundry Soap/ Anti-Bacterial Soap, 1991;Jaw Plate and Toggle Plate for Jaw Crusher Wearing Parts Spare Parts, 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;PP Coated Pipe Machine Extruder 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.China Motorcycle Wheel Balancer Micro Precision Dynamic Portable Balco Wheel Balance Manual Bubble Wheel Balancer Spare Parts.

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%Similar Kavo8000b Fiber Optic Turbine with Water Volume Adjustable Coupling (KV180). 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.
