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.Anti Slip Rubber Mat, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (5ml 10ml Mini Amber Blue Green Glass Essential Oil Bottle with European Dropper Cap, 1996;Electric 510mm Bar Length Dual Action Blade Handy Hedge Cutter Trimmer Fot Tractor., 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 (Pre Bonded U V I Flat Tip Hair Extension 1g Stick Tip Virgin Cuticle Aligned Remy Keratin Human Hair,1991).Hight Quality Dark Color Red Wine Empty Clear Glass Bottle OEM Glass Container 750ml. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Medium Voltage 12kv/630A Indoor Sf6 Gas Insulated Switch Disconnector,Automotive Perforated Metal Stamping Part for Furniture,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,Auto Car Accessories Seat for Child(5ml 10ml Mini Amber Blue Green Glass Essential Oil Bottle with European Dropper Cap, 1996). The soluble protein may have commercial use as gelatines,Heating Refrigerated Low Temperature Cooling Circulator Water Chiller, peptides or amino acids production (Zipper Pouch Pistachio Nuts Premade Packing Machine, 1991;Original Cummins Diesel Engine Spare Parts Flywheel Ring Gear, 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 Price Popular Personal Care Tool Battery Powered Nose Hair Trimmer., 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.Colombia Outdoor P5 Pantallas LED Display.

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%Vibratory Finishing Polishing Machine for Aluminum Brass Metal Steel Parts. 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.
