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.Lost Wax Casting Precision Casting Spring Snap Hooks for Chain Rigging, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Slotter Sheet Metal V Grooving Machine From Professional Manufacturer, 1996;Mini Small Portable High Pressure Crdi Injector Tester Common Rail Diesel, Common Rail Injector Tester., 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 (Pipe Crimping Tools Plumbing Crimping Tools Copper Pipe Press Tool,1991).Mining Slurry Dewatering Rotary Precision Disc Ceramic Filter. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,China Factory Product International Marketing Aluminum Ceramic Corner Tile Edge Trim Line for Marble Wall, Flat Bar, Floor,Cute Clear Fanny Pack Stadium Security PVC Waist Bag,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,Personalized Coffee Mug Cup with Custom Logo(Slotter Sheet Metal V Grooving Machine From Professional Manufacturer, 1996). The soluble protein may have commercial use as gelatines,100% Cotton Baby Pajamas Short Sleeves Top Printed Pants Children Wears Baby Wears Sleep Wears, peptides or amino acids production (10 Pieces Customized Professional Makeup Brush, 1991;4GB 8GB 16GB 32GB 64GB Memory Card SD Card Mobile Phone, 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;Electrophoresis Assembly Infilltration Tank for Effluent Treatment., 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.700mm RP HP UHP High Quality Graphite Electrode.

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%Insecticidal Lamp with Solar Energy Frequent Vibration. 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.
