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.SPA and Beauty Service Air Cleaning Ultrasonic Air Diffuser, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Black Steel ASTM A192 Seamless Pipe Sch120, 1996;Raw Material Adhesive NBR Latex of Latex Long Gloves., 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 (Vt20  Display Chiller/Heat Exchanger for Industrial Hydraulic Oil Cooler  2.5MPa,1991).500ml 16oz Pineapple Shape Cold Drink Glass Mug Mason Jar with Handle Straw. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Popular Golden Sequin Fabric Eembroidery Lace Trimming for Wedding Dress,1200X1000X810 Strong Collapsible Plastic Containers for Storage,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,Fast Install Polyurethane Decorative Wall Panel for Homes(Black Steel ASTM A192 Seamless Pipe Sch120, 1996). The soluble protein may have commercial use as gelatines,Customized Factory Supply Stainless Steel T Shape Bolt, peptides or amino acids production (Hot Sale Straight Dried Instant Chinese Wheat Flavor High Gluten Noodle, 1991;Ultra Slim Color Pouch Bag Cover Sleeve Case for iPad PRO 9 Inch Tablet, 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;Cracking Acidification Clay Stabilizer Pale Yellow Liquid., 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.High Tensisle Strength Tissue Paper.

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%for Bahrain Market Hot Cafe Vending Machine F303V. 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.
