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.Nutrition Enhancer Environmental Nutritional Yeast Powder, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Decor Paper Laminate Wood Flooring Manufacturer Also Wood Grain Design for 8mm 12.3mm Laminated Flooring, 1996;CO2 Glass Tube Ss Laser Marking Machine for Different Non Metal Marking Machine., 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 (New Technology P8 Outdoor LED Display Screen Videowall for Propaganda Board,1991).Best Selling Anti-Aging Remover Hyaluronidase Injection Hyaluronic Acid Lyase. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Quality Army Captain Navy Blue Color Hat for Army Tender,Women′s Tote Bag Small Canvas Shoulder Bag Daily Working Handbag,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 Efficiency Mini-Pleat HEPA Filter (H13/H14)(Decor Paper Laminate Wood Flooring Manufacturer Also Wood Grain Design for 8mm 12.3mm Laminated Flooring, 1996). The soluble protein may have commercial use as gelatines,Modern Vertica Parking Garage System, peptides or amino acids production (Wholesale Price of Citalopram Hydrobromide Powder Sample Packing for Test, 1991;Galfan Wire (Aluminium-Zinc Alloy coated), 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;1000base Single Mode 1310nm LC SFP Module 20km 1.25g., 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.Reflective Aluminum Foil Fiberglass Cloth Tape (flame retardant).

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%FRP Counter Flow Low Noise Round Type Cooling Tower 600rt. 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.
