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.Plastic Twist Top Blood Lancet with Ce, ISO, FDA Certificated, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Automatic Ice Cube Maker Ice Making Machine with Selectable Cube Size, 1996;Industrial Carbon Steel Wire Hose Hydraulic Pipe., 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 (24k Gold Whitening Anti-Spot Mask,1991).Clay Tiles Making Machine with Latest Technology. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,DIN Standard Gratings/Gavlanized Steel Grating,50mm Magnetic River Water Sewage Flow Meter for Acid,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,PE Biodegradable Sheet Product Line/Single Screw Extruder(Automatic Ice Cube Maker Ice Making Machine with Selectable Cube Size, 1996). The soluble protein may have commercial use as gelatines,27L/Min Water Exchanger Heat Pump Mold Temperature Machine, peptides or amino acids production (Felt Belt for Textile Compactor, 1991;Grade a Highest Efficiency Yingli BS OHSAS Yge 12bb Mbb 60 Cell 285W Poly Solar Cell for House Use with Best Price in Egypt, 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 Soft Enamel Souvenir Metal Medal Sport Medallions., 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.20L Water Tank Lid Mold 3D Printing Samples Available.

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%ASME/ASTM Butt-Welding Stainless Steel Plate Flange. 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.
