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.Chinese Knuckle Boom Hydraulic Truck Mounted Crane for Sale, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Original Testo 174t Mini Temperature Data Logger No. 0572 1560, 1996;Domestic and Industrial Wastewater Treatment Plant Mbr/Waste Water Treatment Plant/Water., 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 (Hot Sale Factory stainless Steel Dining Chair OEM Dining Furniture,1991).New Style Fashion Custom Branded Printing Sublimation Plain Summer Merino Wool Cotton Bamboo Polyester Leisure Quick Dry Undershirt Slim Fit Long Sleeve T-Shirt. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Whole Set Gas Spring Strut for Furniture,Dia. 5.5mm Bonding ND: YAG Laser Rod Lens,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,CNC Machining Turning Anodized Aluminum Worm Gear(Original Testo 174t Mini Temperature Data Logger No. 0572 1560, 1996). The soluble protein may have commercial use as gelatines,China Solar Panel Solar Cell Photovoltaic 300W Hot Sell, peptides or amino acids production (Vacuum Coating Machine Water Chiller (CW-6300AN), 1991;Planter Moving Round Planter Saucer Casters Plant Trolley (M), 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;1060 1100 3003 3105 5052 5005 Aluminium Coils Manufacturer in China., 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.Electric/Motorized Soft Seal Flanged Butterfly Valve (GAD941X).

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%Rg178 Coaxial Cable with Ipex/Ipx Female to SMA Male Right Angle. 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.
