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.S235jo S235jr Steel Pipe Tube Shs Rhs, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Seamless Long Sleeve T Shirts Super Soft Lightweight Workout Gym Clothing, 1996;Pre-Seasoned Cast Iron Mini Oval Casserole Pot., 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 (Stainless Steel Square Wire Mesh Netting with SGS,1991).Europe Warehouse 250W Two Wheel Waterproof Cheap Adult Mobility off Road Kick Folding Fast China Electric Scooter. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Solar and Industrial Homehold Sine Wave Smart Power Inverter100W 500W -6000W DC12V-DC60V to 220V Output with Digital Display,Outdoor Garden Save Energy with Solar Flame Wall Light,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,CE/PED Approved Small Laminated Glass Autoclave (Diameter 1600mm)(Seamless Long Sleeve T Shirts Super Soft Lightweight Workout Gym Clothing, 1996). The soluble protein may have commercial use as gelatines,Factory Price Customized Design Doll Diamond Floating Soft PVC Luggage Tag, peptides or amino acids production (Air Cooling Gas Powered Chain Saw with Dual Metal Blade 600mm Length, 1991;Non Stick Silicone Coated Fiberglass Cloth, 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;Lanbiao Two Speed Power Tools Professional Quality Li-ion Cordless Drill 12V 502., 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.Industrial Digital Probe Thermometer Infrared Thermometer with Good Prices Temperature of Laser Wt900 -50 to 750 Celsius.

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%PVC Fabric Rapid Roller Shutter for Clearn Room. 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.
