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.Pharmaceutical Peptide Ghrp 2 Acetate CAS158861-67-7 Ghrp-2, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Big Capacity Crystal Clear Glass Wine Bottle with Screw Cap, 1996;Spare Parts for Caterpillar Construction Machinery., 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 (Hpa Tank Refill Scuba Tank Air Fill Adapter Gas Transfer for Diving High Pressure Tank,1991).50 Grams Ozone Producing Device for Makeup Toner Producing Plant. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Flat Pack Temperary Container House 20FT 40FT,Sweat Suit for Women Three Piece Tracksuit,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,Cold Rolled Stainless Steel Strip /Coils 410/430/409(Big Capacity Crystal Clear Glass Wine Bottle with Screw Cap, 1996). The soluble protein may have commercial use as gelatines,FRP Water Tank GRP Fishing Tanks From Factory Supply, peptides or amino acids production (Decorative House Stone Coated Metal Roof Tile, 1991;Integrated Crawler Rotary Underground Fully Hydraulic Tunnel Jumbo Drilling Rig, 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;6LTR Stainless Steel Foam Empty Fire Extinguisher Cylinder., 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.Laser Marker Animal Ear Tag Optical Fiber Laser Marking Machine System.

Home Products 16′ Perforated Flex Pipe(2.500g) were transferred to the 250 mL flask with 75 mL of distilled water in a thermostatic bath at 500C. After 2 h, the solid was filtered using qualitative filter paper (Tube Mills for Thin Wall Tubing).1220 Fork Length 3-Wheel Electric Forklift Truck(branch B) until pH 10, in order to precipitate Cr(OH)3. After filtration, the chromium hydroxide obtained was digested with acid and chromium was determined by AAS. The solid residue (branch A) was treated with 3% magnesium oxide (w/v) and 10%Hidrotek Portable Suitcase Design Reverse Osmosis Demo Kits0C for 24 h. The sample was then treated with 1%FM USB Radio Audio Power Amplifier for Home Bar Club0C for 2 h. After this treatment,Functional Manual Steel Wheelchair Folding 12 Inch and 24 Inch Rear Wheels Exhangeable.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,450ml Sublimation Stainless Steel Milk Bottle (Colorful).

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%Lower Noise Colled Rolled Ball Screw. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
