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.Gl-321t IP Network Sound System Ceiling Speaker Indoor PA Speakers, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (ASTM A240 304 316L No. 1 Stainless Steel Sheet, 1996;12V 24V 220V Digital Temperature Controller., 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 (Bathroom Tempered Glass Shower Square Swing Cabine 80*80 Cabin Price,1991).25kg Fertilizer Belt Packing Machine for Special Materials. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Wholesale Fashion Driving Mirror Lens UV400 Polarized Clip on Sunglasses,Rotor High Output Electric 120 Watt Motor,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,Flexible Layflat Plastic PVC Water Discharge Pipe Hose Assemby(ASTM A240 304 316L No. 1 Stainless Steel Sheet, 1996). The soluble protein may have commercial use as gelatines,Hv-02 1/4 Inlet Outlet Exhaust Three 3 Position Four 4 Way Pneumatic Air Hand Lever Valve Center Closed, peptides or amino acids production (Acf Cof Tab Bonding Machine for Flex Cable Repair of LED LCD Bonding Machine, 1991;Factory Direct Selling Price Mix Color UV Inkjet Printing Glass Mosaic Tile, 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;Rpl Straight Socket and Plugs Male Thread., 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.46, 49, 55, Inch Ultra Narrow Bezel LCD Display Video TV Wall Monitor Splicing Screen Controller Advertising Video Wall.

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%Dentist Used Metal Dental Steel Nickel Chrome with Beryllium Alloy. 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.

CONCLUSIONS

Rapid Prototyping for Aluminum Parts Sometimes Steel or Brass. Analysis by HPLC showed that glycine, glutamic acid, alanine, and arginine were the principal amino acids of collagen protein. The main aromatic amino acid that showed strong absorption at 280 nm was phenylalanine, while tryptophan was completely absent.
