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.Medical Packing Self Sealing Sterilization Pouch, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Water Filter Cartridge PP Sediment Filter Cartridge, 1996;Wholesale Military Black Color Clothing /Army Bdu Uniforms Surplus Stock for Sale., 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 (Disposable Skin Stapler (CSPF-35W),1991).Custom Made Restaurant Furniture Artificial Stone Round Coffee Dining Table (190827). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,New Customized Mug Heat Press Machine Price,All-Automatic Powder Wrapping Machine for Tomato Sauce, Lotion Noodle Jam,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,Wholesale Plastic Pet Bowl with a Cap Pet Basin Bowl Factory(Water Filter Cartridge PP Sediment Filter Cartridge, 1996). The soluble protein may have commercial use as gelatines,Shengya Steel Concrete Electric Pole Mould, peptides or amino acids production (Outdoor Enjoy Music V4.2 Mini Wireless Stereo Bluetooth Speaker, 1991;Quick Field Assembly Fiber Optic FC Mechanical Fast Connector for FTTH Cable, 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;Wallbox Type 2 32A 22kw Three Phase EV Charging Point EV Charger for Electricvehicles., 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.China Manufacturer Garbage Incinerator.

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 150m/Min Multi Color Uesd Motor Roto Gravure Rotogravure Printing. 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.
