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.Top Furniture Cheap Iron Stacking Banquet Hall Chairs, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Luxury Transparent Colorful Plastic Electroplating Pump Cosmetic Packaging Airless Bottle, 1996;Sports Compression Ankle Brace Breathable Ankle Support Plantar Fasciitis Socks., 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 (High Lumen Aluminum Shell 12V DC 30W LED Street Light Bulb,1991).Magic DIY Bouncing Plasticine Magnetic Thinking Putty Toy for Kids Adults. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Document Storage Durable Metal Wire Mesh Decking for Pallet Rack,Mosquito Proof Fiberglass Fly Screen,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,Crystal Glass Rose Flower Wedding Table Decorations (JD-CF-100)(Luxury Transparent Colorful Plastic Electroplating Pump Cosmetic Packaging Airless Bottle, 1996). The soluble protein may have commercial use as gelatines,Walnut Birch Basswood Walnut Children Craftes Toyslaser Cutting Plywood Board, peptides or amino acids production (19m Mobile LED Display Billboard for Advertising Screens, 1991;Baby Gym Toy with Piano Plastic Baby Cartoon Toys (H8732042), 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;Replica Car Wheels with 20inch for BMW Car., 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.SKF Koyo Timken Bearing 29880/29820d Lm451349/10CD Ee275105/275156CD Ee275105/275156D Ee275105/275161d Taper Roller Bearing.

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%Cummins Diesel Engine ISM11 Qsm11 Fuel Injector Repair Rebuilt Parts Injector Cup Nozzle 4903474. 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.
