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.2019 High Quality 12V 3.1A Quick Charge QC 3.0 Phone Charger 2 USB Port Car Charger Custom Logo, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Unique Design for Handle Champange Glass Uesd for Hotel and Restaurant, 1996;150mm Interior Decorative WPC Ceiling Tiles PVC Wall Panels., 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 (Best Design and Nice Price All in One Solar Street Light,1991).Customized Large Ss Stamping/ Bending Sheet Metal Parts. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High-Quality 201 304 410 430 Grade Mirror Finish Stainless Steel Sheet,UV Laser Marking Machine (with Air Cooling System),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,Energy Saving Street Light E27 E40 27W LED Corn Bulb(Unique Design for Handle Champange Glass Uesd for Hotel and Restaurant, 1996). The soluble protein may have commercial use as gelatines,Mechanical Seal, Auto Cooling Pump Seal, Automotive Water Pump Seal, peptides or amino acids production (Private Label Customized Teeth Whitening Activated Charcoal Toothpaste OEM, 1991;Aluminium Machining Parts Turning Service Coffee Machine Milling Machine Spare Parts, 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 Quality Garden Tools 22t Carbon Steel Leaf Rake with Fiberglass Handle., 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.Ye3 Ie3 Premium Efficiency IC411 Tefc Three Phase AC Electric Induction Motor High Pressure Washer Ye3-160L-2 18.5kw.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Snf-B/Fdn-B/ Sodium Naphthalene Formaldehyde/ Water Reducing Admixture.

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%Food Package Aluminum Foil Tray Making Machine. 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.
