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.4in1 Functional Diamond Dermabrasion Hydra Deep Facial Cleansing Peeling Microdermabrasion Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (6 Cavities Automatic Bottle Blow Moulding Machine / Pet Stretch Molding Machine/ Pet Bottle Blower, 1996;Chemical Equipment & Machinery Gas Station CO2 Beverage Aluminum Gas LPG Gas Cylinder., 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 (10g Non-Woven Fabric Silica Gel Desiccant,1991).Soosan Excavator Hydraulic Hammer for Construction Demolition. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Hh-10 Automatic High Speed 1-Die 2-Blow Screw Cold Heading Making Machine with Full Cover,Mattress Sewing Computerized Chain Stitch Multi-Functional Cover Quilting Machine,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,Easy Installation High Tensile Strength Aluminium Cabinet Door and Frame System Profile(6 Cavities Automatic Bottle Blow Moulding Machine / Pet Stretch Molding Machine/ Pet Bottle Blower, 1996). The soluble protein may have commercial use as gelatines,Electric Paint Sprayer Pump, Cylinder Liner, Piston Rod with Repair Kits for Wagner 940/950, peptides or amino acids production (Magic DIY Bouncing Heat Sensitive Thinking Putty Intelligent Play Dough Toys, 1991;600*600mm 800*800mm CO2 Laser Carving Machine for Paper Metal Tube, 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 Cacao Bean Grinder Cocoa Butter Making 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.Nh4cl White Granular Agricultural Grade Ammonium Chloride.

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%Customizable Oxygen Concentrator 20 Lpm Pressure Swing Adsorption Plant. 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.
