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.3D Creative Design Metal Medal Promotion Gift of Sport, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Ad-L13 Black Perfume Plastics Vial Bottle 10ml, 1996;Patchwork Color Outdoor Covers Stretch Waterproof Auto Car Cover., 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 (EAS Hard Tag EAS Tag Security Tag MIDI Dome (T012),1991).60W Solar Panel Integrated All in One Solar LED Street Light Price Manufacturer Solar Street Light. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Universal Mirco Forklift Car Bus Truck Seats Switch Sensors,Epimedium/Horny Goat Weed Extract/C Yin Yang Huo Extract/Barrenwort Extract Lcariin/Epimedium Extract Powder,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,Mexico Single Expansion Anchor with YZP(Ad-L13 Black Perfume Plastics Vial Bottle 10ml, 1996). The soluble protein may have commercial use as gelatines,Best Supplier Youfa Brand Schedule 40 Galvanized Steel Pipe, peptides or amino acids production (SSAW Steel Pipe API 5L Psl2 with Stainless Steel Sheet, 1991;Ribbon Production of Various Specifications of Gold and Silver Wire Rope Kraft Paper Rope Hand Rope, 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;Whole Absorbtion Flexo Printing Soltting Die Cutting Machine., 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.Factory Price 4X6 Acrylic Magnetic Photo Frame.

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%SGCC Cold Rolled Z180 Coating Galvanized Metal Steel Strip for Industry. 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.
