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.FM USB Radio Audio Power Amplifier for Home Bar Club, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Functional Manual Steel Wheelchair Folding 12 Inch and 24 Inch Rear Wheels Exhangeable, 1996;Hot Sell Mechanical Bar Screen for Water Treatment., 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 (Glow Powder for Luminous Coating,1991).700 mm RP HP UHP Graphite Electrode Sold at Factory Price. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Foton Right Hand Drive High Efficiency Suction Pump Sewer Scavenger 2000L Small Sewage Suction Truck,Union Metal Steel Building and Construction Material,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,Factory Directly Supply 10HP Air Cooled Water Chiller Best Price Industrial Chiller(Functional Manual Steel Wheelchair Folding 12 Inch and 24 Inch Rear Wheels Exhangeable, 1996). The soluble protein may have commercial use as gelatines,450ml Sublimation Stainless Steel Milk Bottle (Colorful), peptides or amino acids production (Lower Noise Colled Rolled Ball Screw, 1991;Sphere Earth Permanent Magnets 216PCS 5mm Neodymium Cube Balls, 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;3.0kw Spindle CNC Router with Certificate for Woodworking., 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.800W Electric Motor Price Lawn Mower Motor Concrete Mixer.

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%Stainless Steel Barbecue Net BBQ Grill Grates Wire Mesh. 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.
