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.20mm 400mm High Pressurer Sch40 Sch80 D2846 PVC CPVC Pipe List Plastic Pipe Selling High Quality PVC Pipe Made in China, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (37PCS 10W LED Zooming Moving Head Light for Stage/Event/Wedding/Disco/DJ/Concert/Performance Light, 1996;Cheap Alloy Snap Hook Clasps, Lanyard D Ring Gold Metal Swivel Snap Hook Dog Strap, Bag Metal Dog Snap Hook Swivel Bulk for Bags., 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 (PCD Concrete Grinding Cup Wheel Diamond Tools for Urethane Epoxy and Paint,1991).Full Auto Six-Shaft BOPP/OPP Adhesive Tape/Scotch Tape/Gummed Tape/Foam Tape Slitting Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Sheet Metal Parts Processing Iron Aluminum Stainless Steel Hardware Parts to Figure Custom Bending,Stainless Steel Pipe Fitting 304 Cross of 3/4 Inch,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,Custom Stainless Steel Jewelry Production by Metal Injection Molding Process(37PCS 10W LED Zooming Moving Head Light for Stage/Event/Wedding/Disco/DJ/Concert/Performance Light, 1996). The soluble protein may have commercial use as gelatines,Factory Directly Selling Engine Standard Spark Plug, peptides or amino acids production (Custom Logo Silicone Wristband, Rubber Wrist Bands, 1991;Custom All Kinds of Acrylic Shoe Display Racks, 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;Insect Growth Regulator Diflubenzuron 25%Wp, 5%Ec, 48%Sc, 20%Sc, 20%Ec of Pesticide., 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.Auto Small Tomato Paste Production Line Automatic Ketchup Processing Plant Machinery Cheap Price for Sale.

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%China Supplier Building Construction Steel Frame (ZY431). 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. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
