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.Rope Making Machine for PP Danline Hawser Marine Mooring Rope Braiding Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Recyclable PU Leather Jewelry Pouch, 1996;Luxury Special Design Decorative Quality Gold Color Office Round LED Standing Floor Lamp (LT-11)., 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 (Activated Alumina Used for Catalyst Carrier in Chemical Industry,1991).High Quality 45W 50W Commercial Recessed COB LED Downlight. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Toyo-Ta Denso 4 Pin Female Wire Harness Ignition Coil Plug Connector,1.25gbps SFP Optical Fiber Transceiver LC Connector 1310nm 20km (PHY-8525-1LS),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,Automatic Liquid Juice Stick Sachet Ice Lolly Pop Packing Machine(Recyclable PU Leather Jewelry Pouch, 1996). The soluble protein may have commercial use as gelatines,Steel Structure Polycarbonate Greenhouse Builder and Contractor and Manufacturer, peptides or amino acids production (High Speed Auto Corrugated Carton Box Paperboard Production Line, 1991;Custom Waterproof BNC Connector for Industry, 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;Indoor Inkjet Media Material., 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.Steel Jacket Steam Insulation Pipeline Production Famouse in China.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Auto Hydraulic Shock Absorber 48510-09K80 for Toyota Hilux Kun25.

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%Electric Massage Bed Pedicure Chair with Double Dust Collector. 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.
