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.CE/PED Approved Small Laminated Glass Autoclave (Diameter 1600mm), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Factory Price Customized Design Doll Diamond Floating Soft PVC Luggage Tag, 1996;Air Cooling Gas Powered Chain Saw with Dual Metal Blade 600mm Length., 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 (Non Stick Silicone Coated Fiberglass Cloth,1991).Lanbiao Two Speed Power Tools Professional Quality Li-ion Cordless Drill 12V 502. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Industrial Digital Probe Thermometer Infrared Thermometer with Good Prices Temperature of Laser Wt900 -50 to 750 Celsius,ANSI/Ssfi & AS/NZS Ringlock Certified Lattice Girder Beam Scaffolding for Construction,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,DC 12V 24V Mini Portable Car Refrigerator Compressor Fridge(Factory Price Customized Design Doll Diamond Floating Soft PVC Luggage Tag, 1996). The soluble protein may have commercial use as gelatines,3000W 4000W High Speed Pipe&Plate Exchange Platform Metal Fiber Laser Cutting Machine with Raycus/Ipg Source 3015gcr, peptides or amino acids production (White/Black/Green Color 600GSM Polyester/PP Non Woven Geotextile, 1991;Hot Sale 100% Polyester Cartoon Kids Sleepwear, 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;Ce Quickclean Hyaluronic Acid Injections for Osteoarthritis Pain., 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.Ozone Generator for Sale/Swimming Pool/Hospitals/Hotels/Wastewater.

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%Cog Graphic FPC LCD Display Module. 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.
