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.Paper New Year Greeting Cards Wedding Invitations Cards, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hoomall Flowers Mixed Patches Iron on Patches for Clothing DIY Fabric Badge Stickers Embroidered Appliques Clothes Repair Crafts (CE01), 1996;BLE5.0 Ttl to Bluetooth Module with at Command., 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 (Metal Spin Round Spray Bottle 8ml 15ml Aluminum Perfume Bottle,1991).Professional Customization Screen Printing Machine for Porous Ceramic. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Fea040b New Arrival Airplane Seat Belt Extender,SS304 316 DIN Standard Ce Stainless Steel Spool Wire for Binding or Weaving,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,Square Shape Glass Candle Holder for One Piece Tealight Candle(Hoomall Flowers Mixed Patches Iron on Patches for Clothing DIY Fabric Badge Stickers Embroidered Appliques Clothes Repair Crafts (CE01), 1996). The soluble protein may have commercial use as gelatines,1.5m Spring Loaded Stainless Steel Cable Retractable Anti Theft Security Tether Pull Box, peptides or amino acids production (Medical Autoclavable Surgical Thoracoscopy Trocar, 1991;DC 12V 24V Mini Portable Car Refrigerator Compressor Fridge, 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;Easy Foldable Kids Walking Chair Toys Baby Walker., 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.Men V-Neck Longline T-Shirt with Color Block Ribbed Trims.

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%Best Price 1.4507/S32550/Alloy 2507 Stainless Steel 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.
