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.E6000 Handheld Three Phase Power Quality and Energy Analyzer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Qg Jg Fg Series Air Dryer Equipment Factory, 1996;Motor Bearing 6014 2RS Deep Groove Ball Bearing., 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 (PP Extended Stretched Wc Toilet Drain Pipe with Steel Wire Reinforced Tube Hose Extrusion Line,1991).Pet Short Fiber Non Woven Geotextile for Landfill Filtration. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Pre Painted Steel Coil and Sheet,Ge-Ding High Voltage Reed Relay Grl 24V Z1-Grl-2412 1X10^10ohm Gd,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,Auto Defrost Supermarket Island Freezer Merchandiser with Integral Compressor(Qg Jg Fg Series Air Dryer Equipment Factory, 1996). The soluble protein may have commercial use as gelatines,8 Inch Computer Program Control 78cm Paper Cutter (QZK780D-8), peptides or amino acids production (Custom Cheap Marathon Sport Towel Microfiber Slogan Towel for Promotion, 1991;Maleic Anhydride CAS 108-31-6, 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;Plastic HDPE Pipe Extrusion 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.Jaguar Jb-390 Automatic PCB Loader and Unloader.

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%Mini Double Hole ABS Plastic CNC Machined Parts Importer. 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.
