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.Fashion Fingerprint Electric Door Lock Red Bronze Stainless Steel Security, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Natural Stones Granite/Marble Stone Water Fountain for Garden Decoration/Landscaping, 1996;Motorcycle Accessories Flexible Natural Rubber Shock Absorber / Dock Silent Buffer Block., 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 Security 13.56MHz MIFARE DESFire EV1 EV2 2K 4K 8K CPU RFID Card,1991).T90 High Power Latching Relay Mini Power Relay. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Customizable Laptop Sleeve Computer Case Bag for MacBook Air 7 8 9 10 11 12 13 14 15 Inch,Auto Accessories Tailored Car Foot Mats Trunk Mats for Lexus GS430,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,Polyglycolic Acid Absorable Suture(Natural Stones Granite/Marble Stone Water Fountain for Garden Decoration/Landscaping, 1996). The soluble protein may have commercial use as gelatines,No. 1062 20PCS Tools, peptides or amino acids production (Ld-Zg002 Special Corrosion and Scale Inhibitor for Chemical Plant, 1991;Aluminum Mould Shoe Mould Making CNC Milling Router 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;High Pressure Fitting Quick Coupling Hydraulic Plug., 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 Quality Products Insulin Syringe/ Insulin Pump with Medical Head Cover.

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%Metal Separating Gold Brass Zippers for Sale. 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.
