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.Ce Approved Sperm Concentration Test for Sperm Density Test, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cao Content Plastic Additives Desiccant Masterbatch for Recycled Plastic, 1996;Heating and Cooling Resistant HDPE Coated Polyurethane Foam Injection Foam Pipe Insulation., 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 (Sand Casting Parts Large Size for Industrial Use,1991).Durable Steel Retainer Plastic Road Safety Trench Cover. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Iron Cast Brake Drums for Trucks,Eco-Friendly Barware Food Grade Stainless Steel 304 Reusable Custom Straws,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,Folding Aluminium Easy Move Choral Stage with Wheels for School(Cao Content Plastic Additives Desiccant Masterbatch for Recycled Plastic, 1996). The soluble protein may have commercial use as gelatines,Factory Direct Sale Turnbuckle Tensioner Open Body Orchid Tightener Rigging Screw Quantity Discounts, peptides or amino acids production (330FT 842-12-12.5 Powder Coated Pasture Sheep Wire Mesh Farm Fencing, 1991;Dental Equipment Dental Intraoral Camera Endoscope 17 Inch LCD Monitor, 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;Computerized Single Fishnet Jacquard Circular Knitting Machine., 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.Low Volume Large Variety Non Standard Customized High Precision CNC Machining Parts.

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%SGS Steel Lab Acid and Alkali Resistance Fume Hood Laboratory Furniture with Ce Certification (JH-FC019). 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.
