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.Polyester Dust Sport Gym Fabric Shoes Drawstring Bag, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Furniture Drawer Factory 2 Drawer Dresser Bedside Cabinet, 1996;1.5 Inch Dn40 48.3mm Scaffolding Tube Pre Galvanized Steel Pipe Price., 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 (Servo System Double Action 1000 Ton Hydraulic Deep Draw Press Machine Stainless Steel Kitchen Sink Manufacturing Machine,1991).Chuke 20W Optical Fiber Laser Marking Machine Printer Engraver. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Fiberglass GRP FRP Sectional Assembling SMC Panel Water Storage Tank,Electrostatic Powder Color Coating Steel Coil Plate High Quality Z30-Z220 PVDF High Tensile High Strength,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,Plastic Food Box Container Covers by Injection Mould Mold Tool(Furniture Drawer Factory 2 Drawer Dresser Bedside Cabinet, 1996). The soluble protein may have commercial use as gelatines,304 Stainless Steel V Shape Powder Mixer Pharmaceutical Mixing Equipment, peptides or amino acids production (Factory Supplier Small Buttons, Cheap, Round Snap Rivet for Shoe Garments Belt Jeans, 1991;Passenger Home Sightseeing Elevator Good Sales with Professional Technology, 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;Vacuum Stainless Steel Casting Products., 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.Chicken Farming Materials Poultry Battery Cages Layer Battery Cage.

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%Energy-Saving Biogas Double Stove for Sale. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
