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.Ipx7 Ipx8 Immersion Tank Waterproof Rain Spray Environmental Test Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Pressure Die Casting Aluminum Die Casting Gear Box Housing, 1996;Top Grade 93% High Purity 5L Flow Home Use Medical Portable Oxygen Concentrator Generator., 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 (Outdoor Portable Charcoal BBQ Grill Barbecue Camping Stove,1991).CZ300 Automatic Switching Galvanized Plate C Z Purlin Roll Forming Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Small Portable Air Water Purifier with Disinfection and Detoxification,Fog Smoke Machine 1500W for LED Moving Head Beam Light DMX,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,1850mm*80mm Stable Power Laser Tube(High Pressure Die Casting Aluminum Die Casting Gear Box Housing, 1996). The soluble protein may have commercial use as gelatines,White Color Premium Quality Disposable Plastic PVC Apron, peptides or amino acids production (Galvanized Bar Grating, 1991;Ring Die Bio Organic Fertilizer Pellet Mill 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;Hot Dipped Galvanized Deer Fence From Factory., 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.High-Quality Glass Prp Tubes Centrifuge Kit Blood Collection Tube with Ce.

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%OEM Composite Machining Phenolic Titanium Parts Products Supplier. 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.
