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.New Style Fashion Custom Branded Printing Sublimation Plain Summer Merino Wool Cotton Bamboo Polyester Leisure Quick Dry Undershirt Slim Fit Long Sleeve T-Shirt, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Whole Set Gas Spring Strut for Furniture, 1996;Dia. 5.5mm Bonding ND: YAG Laser Rod Lens., 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 (CNC Machining Turning Anodized Aluminum Worm Gear,1991).China Solar Panel Solar Cell Photovoltaic 300W Hot Sell. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Vacuum Coating Machine Water Chiller (CW-6300AN),Planter Moving Round Planter Saucer Casters Plant Trolley (M),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,1060 1100 3003 3105 5052 5005 Aluminium Coils Manufacturer in China(Whole Set Gas Spring Strut for Furniture, 1996). The soluble protein may have commercial use as gelatines,Electric/Motorized Soft Seal Flanged Butterfly Valve (GAD941X), peptides or amino acids production (Custom ABS&POM&PP&PC&Acrylic Plastic CNC Machining Turning Parts, 1991;CNC Machining Non-Standard Hardware Parts, 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;DOT Aluminum Beverage CO2 Gas Cylinder 5lb 10lb 15lb 20lb., 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.Galvanized Solar System Mounting Bracket Connector.

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%3HP Industrial Cooling System Water Cooled Chiller. 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.
