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.7628 Fiberglass Cloth/Fabric, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Stainles Steel Cartridge Filter, 1996;750ml Long Neck Dark Green Color Glass Bottle for Wine., 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 (Floral Kids PVC School Raincoat,1991).MB-Z700 10-12t/H Hot Sale Wood Log Debarking Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Fs2121 Locking Latch Flush Stainless Steel and Flush Paddle Latch with Truck Toolbox Lock,Microsynthetic Fiber Virgin Homopolymer Polypropylene Monofilament Fibermesh,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,78mm Aluminum Gold Color Plastic Jar Screw Cap(Stainles Steel Cartridge Filter, 1996). The soluble protein may have commercial use as gelatines,Best Price 100kVA/150kVA Cummins Power Generator Diesel Engines, peptides or amino acids production (1008 Spindles Auto Doffer Machine for Spinning Ring Frame Polyester Yarn Winding Spinning Machine Cotton Wool Thread Ring-Spun Yarns Making Machine, 1991;0.5L Plastic Pet Water Bottle Blower Molding Machine/Pet Bottle Making, 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;Cheap Stainless Steel Mirror Home Panoramic 6 Person Residential Passenger Lift Elevator., 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.High Temperature & IR Drying Electronic Oven / Furnace.

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%High Quality Aluminum Street Light Pole. 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.
