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.Best Selling Wooden Grain Metal Aluminium Fence Panels for Sale, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (5 Liter Packed Medical Ultrasound Gel with Ce and ISO, 1996;New Vmc Machine Auto Parts Processing CNC Vertical Machining Centre., 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 (Hot Selling Porcelain White Coffee Mug with Electroplate Handle Custome Printed Character,1991).Etched Stainless Steel Titanium Sheet. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Heat Protection Thermal Insulation PTFE Coated Aluminized Fiber Glass Fabric,Ceramic Tile Cutting Tool Diamond Saw Blade with Hot Pressed,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,Cold Rolled Galvanized Carbon Hot Welding Stainless Steel Pipe Round Seamless Stainless Steel Tube (403/408/409/410/416/420/430/431/440/440A/440B/440C/439/443)(5 Liter Packed Medical Ultrasound Gel with Ce and ISO, 1996). The soluble protein may have commercial use as gelatines,33kv Electrical Automatic Voltage Regulator, peptides or amino acids production (4 Gang 1 Way Electrical Fitting Ce Certificate, 1991;High Temperature Resistance Diamond Wire Saw for Granite Quarry Diamond Wire Rock Saw, 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;Pharmaceutical Grade Raw Powder Goserelin Acetate CAS: 145781-92-6., 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.PPR PVC Polyurethane Insulated Pipe Extrusion Production Machine.

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%Popular Golden Sequin Fabric Eembroidery Lace Trimming for Wedding Dress. 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.
