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.Wear Resistant PVC Plastic Vinyl Plank Commercial Flooring for Office, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Nice Quality Coloring Printing Children Board Book Printing, 1996;Cheap Bedroom Furniture Popular Wardrobe Set (CAS-BD1808)., 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 (Fabric/Leather/Foam/Rubber/Fiber Digital Knife Ctting Cutter Machine,1991).Sand Agent Tp40 Is an Ideal Art-Type Additive for Powder Coating. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Microfiber Polyester Twill 150d Textile for Apron Garment Cushions Baby Trolley,Custom Logo Packaging Nicotine Free Vape Ocitytimes Minibar Disposable Pen,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,5km City Surveillance Network Infrared Laser PTZ Camera(Nice Quality Coloring Printing Children Board Book Printing, 1996). The soluble protein may have commercial use as gelatines,300 M Portable Water Well Mining Exploration Core Drilling Rig, peptides or amino acids production (Foteck SSR 40da Solid State Power SSR Relay, 1991;2015 New Square Folding Ajustable Wall LED Bathroom Mirror, 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;Equipment Manufacturers Mayflay Sales Semi-Auto Dry - Suction Commercial Sandblaster for Motorcycle Frame Surface Cleaning with Light Gun & Nozzle., 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.13.8cm Reed Diffuser Clear Glass Bottle for Aroma.

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%Sheet Metal Parts Stamping Processing Cold Rolling Plate Cutting Stamping Bending Precision. 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.
