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.Equipment Manufacturers Mayflay Sales Semi-Auto Dry - Suction Commercial Sandblaster for Motorcycle Frame Surface Cleaning with Light Gun & Nozzle, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (13.8cm Reed Diffuser Clear Glass Bottle for Aroma, 1996;Metal Cutting Machine CNC Plasma Cutter., 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 (Medical Suction Connecting Tube with Yankauer Suction Handle,1991).Surface Mounted Wall Light for Home Decoration Waterproof. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Yhzs60 Mobile Concrete Batching Plant, Portable Concrete Mixing Plant, Portable Ready Mix Concrete Batch Plant,Self-Propelled Wheel Farm Using 3 Rows Corn Harvester,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,Right Angle Worm Gearbox for Food and Beverage and Packaging Machines(13.8cm Reed Diffuser Clear Glass Bottle for Aroma, 1996). The soluble protein may have commercial use as gelatines,Manufacturer High Strength Carbon Steel Heavy Hex Nut, peptides or amino acids production (Professional Quantitative Detergent Powder Filling packaging Washing Powder Packing Machine, 1991;Stainless Steel Seamless Coil Tube ASTM A249/A269, 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;The Cheapest Hot Sale Agricultural/Commercial Plastic Greenhouse (JIT-406021PT)., 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.Quality Control High Purity 99% Ceftiofur Sodium Powder CAS104010-37-9 in Stock.

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%Premium quality for Potassium Humate powder. 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.
