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.Non Standard U Channel Steel, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Socket Flange, 1996;Dn32 (11/4) BSPT Thread Air Actuated Piston Valves., 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 (Free Sample Cheap Customized Elastic Nylon Fabric Woven Cloth Wrist Band for Events,1991).Foam Cutting 9.0kw Atc Spindle CNC Wood Engraver Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Disposable Sterile Twist Top Blood Lancet,Industrial Control Housing with Plate Shape (XD-CC04),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,Customized Precision Hydraulic Cylinder Metal Machinery Parts for Forklift(Socket Flange, 1996). The soluble protein may have commercial use as gelatines,Low Fuel Consumption Diesel Generator Economic Diesel Power 80kw 100kVA, peptides or amino acids production (Wholesale Price Auto Iridium Spark Plug for Turbo Trumpchi Cars, 1991;CNC 3 Axis Milling Machining Center, 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;Hot Sale Bathroom Downlight LED 10W Ceiling Light IP54 Spot Light Fitting., 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.Variable 50Hz 22kw AC Drive 3 Phase Frequency Inverter.

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%Automatic 0.5-1.2mm Aluminum Channel Letter Bending Flanging Machine. 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.
