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.Barricade Tape, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Brightness White Color IP20 SMD5050 Chip 30LEDs 7.2W DC24V LED Strip, 1996;Fully Automatic Industrial Microwave Dehydrator., 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 (Air Compressor Storage Tank Air Compressor Receiver Air Tank (300L),1991).Oral Thermometer. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Mobile Computer Workstation Dual Monitors 10-24 Height Adjustment (PC 1602BAS),Wood Fireplace Double Skin Chimney Flue Pipes,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,PMMA / Acrylic Panel From Leading Manufacturer for Building/Decoration Material(High Brightness White Color IP20 SMD5050 Chip 30LEDs 7.2W DC24V LED Strip, 1996). The soluble protein may have commercial use as gelatines,High Sensitivity Ground Metal Detector Searching for Treasure, peptides or amino acids production (Aluminium Profile Bending Machine for Insulating Glass, 1991;Stainless Steel Standard Type Steel Hexagon Socket Head Cap Screws, 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;304 Thick Wall Pressure Vessel Heat Exchanger Pipe., 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 Betaine Anhydrous with Best Price107-43-7.

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%China Manufacturer Export Copper Foot Tap/Valve (HFV-001). 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.
