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.1g, 2g, 5g, 20g Silica Gel Desiccant for Food Products, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Blank Custom Fitness Leggings Women High Waisted Compression Yoga Leggings for Women, 1996;High-Performance Thermal Break Profiles Aluminium for Doors and Windows., 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 (Design Luxury Moon Cake Box with Hot Stamp Logo,1991).Standard Industrial Double Nut Ball Screw Dfu Series. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Automatic Self-Washing Stainless Steel Candle Filter, Self-Cleaning Filter, Diatomite Earth Beer Filter,Custom LCD Video Brochure Card/Video Greeting/Wedding Card/Video Business Card,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,Customized Logo Outdoor Hanging Swinging Camping Hammock(Blank Custom Fitness Leggings Women High Waisted Compression Yoga Leggings for Women, 1996). The soluble protein may have commercial use as gelatines,EPDM 1/4′′ X 50 Foot Red / Green Twin Hose with B B Fittings, peptides or amino acids production (Custom Logo Aluminum Foil Wallet ID Credit Card Holder Anti RFID Scanning, 1991;Hiwin Mgn Series Linear Guide Rail and Slide Block Mgn9h, 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;Metal Detector for Gold, Silver, etc Underground Metel Detector., 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.Hing Quality Rubber O Ring in Motor High Pressure.

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%Carbide Rod H6 Tc Rods. 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.
