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.Rutile Titanium Dioxide Exterior Emulsion Paint, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Promotional Multi-Function CO2 CNC Control Table Laser Cutter Engraving Supplier, 1996;Cheap CNC Plasma Cutter for Sale with Flame CNC Steel Sheet Cutting Machine for Round Tube Cutting Manufacturer Factory Plasma Cutting Machines., 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 (Stainless Steel Hole Punching Machine/ CNC Perforation Machine,1991).Rockwool Insulation Pipe for Bolier with Aluminum Foil Steam Tube. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Pet and PP Geobag with UV High Strength Thermal,3000mm Sliding Table Panel Saw with 45 Degree Cutting MDF,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,Magnetic Latching Relay for Health Life(Promotional Multi-Function CO2 CNC Control Table Laser Cutter Engraving Supplier, 1996). The soluble protein may have commercial use as gelatines,More Cavities Plastic Mould Design, peptides or amino acids production (Energy Conservation Electric Single Servo Turret Punch Press Machine D-Es300, 1991;High Quality 14AWG 16AWG USA spiral Power Cord to IEC C13, 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;Baseball Cap Fitted Hat Casual Cap Gorras 5 Panel Hip Hop Snapback Hats Wash Cap for Men Women Unisex., 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.Soft magnetic alloy 1J38 rod / Ni38Cr13/38H14X.

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%9mm/12mm Seven Color Exposed Luminous Pixel String LED. 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.
