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.ISO9001 & Ce Certificated Superfine Cocoa Cake Powder Grinder Mill, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wiskind Hot-Rolled Low Cost Commercial Steel Structure Greenhouse, 1996;Baking Soda 99.8% Min Sodium Bicarbonate., 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 (BS1387 Class B 2 Inch Sch40 Gi Pipe Galvanized,1991).4in1 Functional Diamond Dermabrasion Hydra Deep Facial Cleansing Peeling Microdermabrasion Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,6 Cavities Automatic Bottle Blow Moulding Machine / Pet Stretch Molding Machine/ Pet Bottle Blower,Chemical Equipment & Machinery Gas Station CO2 Beverage Aluminum Gas LPG Gas Cylinder,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,10g Non-Woven Fabric Silica Gel Desiccant(Wiskind Hot-Rolled Low Cost Commercial Steel Structure Greenhouse, 1996). The soluble protein may have commercial use as gelatines,Soosan Excavator Hydraulic Hammer for Construction Demolition, peptides or amino acids production (Hh-10 Automatic High Speed 1-Die 2-Blow Screw Cold Heading Making Machine with Full Cover, 1991;Mattress Sewing Computerized Chain Stitch Multi-Functional Cover Quilting Machine, 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;Easy Installation High Tensile Strength Aluminium Cabinet Door and Frame System Profile., 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.Electric Paint Sprayer Pump, Cylinder Liner, Piston Rod with Repair Kits for Wagner 940/950.

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%Ye3 Ie3 Premium Efficiency IC411 Tefc Three Phase AC Electric Induction Motor High Pressure Washer Ye3-160L-2 18.5kw. 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.
