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.Orange Monofilament Fishing Tackle Nylon Fish Net, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Crushed Knitting Velvet Sofa Fabric Furniture Fabric (CD002), 1996;By6-8-200-L Automatic Doypack Premade Pouch Packing Machine., 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 (Diameter 1300mm Lifting Electro Magnet for Cast Iron,1991).High Purity Magnesium Metal Ingot/Pure Magnesium Alloy Ingot 99.98% 99.95%. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Evaporator Finned Tube,Men Training Sportswear Collection Muscle T Shirt Function Vest Fitness Shirts Sport Tops Gym Activewear,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,Winter Design Acrylic Beanie /Bobble Jacquard Hat with Flowers /Machine for Knitted Winter Cap with Embroidery Circular Hat Knitting Machine(Crushed Knitting Velvet Sofa Fabric Furniture Fabric (CD002), 1996). The soluble protein may have commercial use as gelatines,100%Polyester Spandex Hotel Chair Cover (DPH7022), peptides or amino acids production (Factory Supply Perforated Metal Mesh, 1991;CNC Turning Center, CNC Horizontal Turning Milling Machine, 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;Factory Hot Sale Decorating The Christmas Tree Polyester Stain Ribbon Pmb-16., 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.Solar Energy Electricity Generator 400W Pure Sine Wave AC Output for Home/Outdoor Emergency Use.

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%Aluminum Die Casting Waterproof Junction Box IP67 Aluminum Outdoor Enclosure. 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.
