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.Replacement Sullair Screw Air Compressor Unloading Valve 250025-655 for Sale, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Factory Price 6000 Series Industrial Extruded Aluminum Tube, 1996;WPC Decking Profile Making Machine., 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 (Pre-Painted Corrugated Steel Sheets/ Galvanized Roofing Sheets for Roofing Tile,1991).CNC Cutting Machine Machining Parts Hardware Vehicle Part Grinding Parts Cutting Machine Hardware Accessories. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Party Mask LED Fiber Dance Princess Feather Mask,80GSM C2s Coated Glossy/Matt Art Paper for Printing,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,Customized High Quality Aluminum Alloy Extrusion Enclosure Extruded Case for Power Inverter(Factory Price 6000 Series Industrial Extruded Aluminum Tube, 1996). The soluble protein may have commercial use as gelatines,Reusable Silicone Straight Straws, peptides or amino acids production (Easy Foldable Kids Walking Chair Toys Baby Walker, 1991;Yellow Hazardous Spill Response Chemical Spill Kits, 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;Anhui Hydraulic Sheet Metal Bending Machine., 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.304 Stainless Steel Standard V-Band Clamps for Turbo.

Travel Canvas Cosmetic Makeup Pouch Bags for Purse with Zipper(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 (Zipper Pouch Pistachio Nuts Premade Packing Machine).Ductile Iron Flanged Swing Check Valve(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%Ozonated Water for Vegetables and Fruits Washing Ozone Generator0C for 24 h. The sample was then treated with 1%Fabric Wrapped Oil Resistant Flexible Rubber Fuel Hose0C for 2 h. After this treatment,Day and Night Zebra Blind Fabric Z1602.

After filtration, the solid Cr(OH)3was kept at 6000C for 2 h,German Technology Automatic Stacking System in Red Brick Automatic Production Line. Proteins were also determined by Biuret and Kjeldhal'Top Quality Galvanized Iron Wire as Binding Wire(High Quality Custom Self Adhesive Leather Patch for Jackets). The filtrate in branch B was treated in the same way as branch B inTwo Inch Ball Valve. The final soluble protein shown were used for peptides separations using gel permeation chromatography,13.56 MHz Fudan FM11RF08 Chip Card.

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%Yutong Zhongtong Higer Golddragon Kinglong Bus Spare Parts Fan Belt. 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.
