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.9.0m Long 26PCS Globe Bulbs Solar Powered G40 LED String Light, for Patio Garden Backyard (Warm white), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (JIS S Type Cast Iron Water Filter Dn25, 1996;Machined Self-Locking Trapezoidal Leadscrew, Power Screw, Translation Screw. Left and Right Hand Screws, Split Nut, Half Nut., 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 (Factor Direct Adult Sex Toy Doll for Male Sex,1991).C Axis CNC Lathe Machine Tool, CNC Lathe Machine Milling, CNC Lathe Machine Price Servo Turret EL52L. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Soundproofing Foam Backed Vinyl 3D PE Foam Wallpaper Brick Factory,WiFi Smart Bulb Alexa Google Home Voice Control Mobile APP Remote Control RGB+W Smart Home Colorful LED Bulb 9W,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,Worm Gear Fluorine Lined Butterfly Valve Flanged Type(JIS S Type Cast Iron Water Filter Dn25, 1996). The soluble protein may have commercial use as gelatines,H. 265 2.0megapixel 4X Zoom (2.8-12mm) IP IR Waterproof Camera, peptides or amino acids production (Poultry House, Livestock, Poultry Farm, 1991;1100 T Aluminum Billet Heating Furnace with Hot Log Shear in Aluminum Extrusion 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;Luxury Nice Designs Mother and Son Size Security Metal Copper Door W-Stz-02-2., 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.Black Slim PU Leather Passport Travel Wallet.

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%4 Drawer Steel Office Vertical Filing Cabinet. 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.
