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.CZ300 Automatic Switching Galvanized Plate C Z Purlin Roll Forming Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Small Portable Air Water Purifier with Disinfection and Detoxification, 1996;Fog Smoke Machine 1500W for LED Moving Head Beam Light DMX., 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 (1850mm*80mm Stable Power Laser Tube,1991).White Color Premium Quality Disposable Plastic PVC Apron. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Galvanized Bar Grating,Ring Die Bio Organic Fertilizer Pellet Mill 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,Hot Dipped Galvanized Deer Fence From Factory(Small Portable Air Water Purifier with Disinfection and Detoxification, 1996). The soluble protein may have commercial use as gelatines,High-Quality Glass Prp Tubes Centrifuge Kit Blood Collection Tube with Ce, peptides or amino acids production (Tire Rubber Powder Recycling Equipment for Sale Truck Tires Rubber Shredding Facility, 1991;Cheap Customized Aluminium Sand Casting, 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 Stand up Coffee Food Packaging Bag with Resealable Zipper., 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.Non-Woven Greenhouse Insulation Felt Making Machine Production Line/ Sell Greenhouse Insulation Quilt Production Line.

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%Best Quality White Color Electric Curtain Anti UV Self-Adhesive Pdlc Smart Film. 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.
