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.Eco-Friendly Biodegradable Fashion Party Supply Striped Polka DOT Printed Paper Straw for Plastic Cup, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Push Pull Small Cable to Cable Connector, 1996;Stainless Steel Seamless Pipe ASTM A312 TP304 316., 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 (Prime Quality ASTM A240 AISI 201 304 316L 321 310S 2b Finish Cold Rolled Stainless Steel Sheets From Tisco,1991).Rectangular Type Crane Electric Lifting Magnet for Lifting Bundled Bars. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Big Chocolate Storage Holding Tank, Chocolate Buffer Tank,Honeyson Safe Lock Hotel Equipment Service Deposit Safety Box Ce,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,Asco 353 Series 3/4 Pulse Valve Solenoid Valve(Push Pull Small Cable to Cable Connector, 1996). The soluble protein may have commercial use as gelatines,China Manufacturer Seamless Rectangular Steel Pipe/Tube for Building Material, peptides or amino acids production (Fine Mist Plastic 0.34 Oz Spray 100ml Airless Bottle, 1991;Purple UL 1095 16AWG Electronic Lead Wire, 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;Brushed Anodizing Aluminum Extrusion Profile for LED., 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.PVC Shrink Wrap Bottle Labels / Pet Heat Shrink Labels for Bottle Caps.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,High Yield Tree Stump Crusher Machine.

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%Diaphragm Valve for Bag Filter Since 1992. 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.
