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.Stainless Steel Whisky Chilling Stones, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Nmsafety TPR Back Cut Resistant Oil and Gas Impact Work Glove, 1996;CNC Automatic Pneumatic Tapping Machine/ Drilling Machine for Fasteners., 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 (Automatic 150m/Min Multi Color Uesd Motor Roto Gravure Rotogravure Printing,1991).Good Quality Custom Car Power Window Cable for Ford Car. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Solar Panel PV System Mc4 Circular Connector,1.5 Ton 15 Kn 3300 Lbs Hydraulic Winch for Lifting and Pulling,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,Hot DIP Galvanized Sewer Cover --Professional Grating Manufacturer(Nmsafety TPR Back Cut Resistant Oil and Gas Impact Work Glove, 1996). The soluble protein may have commercial use as gelatines,Industrial Pouring Ladle Steel Furnace Casting Ladle for Casting, peptides or amino acids production (Boiler Fin Tube, Hot Steam Ot Water Cooling ASME SA179 SA192 Fin Tube Wall, 1991;Plastic Recycling Centrifugal Dewatering Machine, 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;Biostimulant Manufacturer Natural Seaweed Extract Liquid Fertilizer., 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.EAS Anti-Theft Optical Security Tag for Glasses Bottle.

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%2018 New Style High Quality Enamel Bowl with Lid. 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.
