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.Fine Bubble Diffuser for Air Purifier, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Btk Iron Tramp Remover/Separator for Magnetic Mine/Magnetic Ore, 1996;High Quality Cheap Price Custom Aluminum Logo Metal Label Plate., 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 (3120/17/38 Boltable Crane Rail Clips,1991).2ml 5ml 10ml 20ml 30ml Pharmaceutical Injection Glass Vial Bottles Medical Packaging for Pipetide. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,China Supplier Rubber Injection Molding Machine with Ce,Tc90 Crosslinked Polyethylene Insulated Aluminum Alloy Cable Made in China,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,Ce 20 Aluminum Frame Urban Electric Folding Bike with Lithium Battery(Btk Iron Tramp Remover/Separator for Magnetic Mine/Magnetic Ore, 1996). The soluble protein may have commercial use as gelatines,High Quality Fruit Lemon H20 Water Bottle Drinking Bottle Infusion Sports Bottle BPA Free, peptides or amino acids production (Manufacturer Kraft Paper Aluminum Foil Laminated Ziplock Custom Printed Mylar Gift Bag, 1991;Honkon Cheaper Price IPL Shr Skin Tightening/IPL Medical Beauty Equipment, 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;High Quality & High Speed Straight Line Wire Drawing Machine., 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 Speed 3000W Fiber Laser Cutter.

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%Heat Exchanger Sheet Boile Water Pipe Carbon Steel Seamless Pipe. 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.
