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

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%Double Coil Control Solenoid Valve of Butterfly Valve. 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.
