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.Zipper Fabric Travel Passport Wallet Organiser, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hot Sale Instax Mini Camera Korea Style Photo Album, 1996;Aluminum Low Profile Adjustable Bracket., 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 (Quality Assurance 6000W Inverter for Solar Panel 5kw/6kw Power Inverter,1991).High Quality Acrylic Beer Display Racks with LED. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Blank Personalized Engraved Plaques Name Metal Art Crafts Plating Copper 3D Marathon Sports Medal with Customized Design (MD04-C),Baby Feeding Chair Plastic Chair for Feeding Hebei China,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,Best Hot 120 Gas Pump Nozzle Fuel Injector Nozzle(Hot Sale Instax Mini Camera Korea Style Photo Album, 1996). The soluble protein may have commercial use as gelatines,Plastic Injection Molding for Auto Parts, peptides or amino acids production (Round Type Twin Screw Extruder Barrel Manufacturer, 1991;ASA-UPVC Anti-Corrosive Composite Roof 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;Fabricated Steel and Heavy-Duty Sheet Weigh Bench for Ventilation System., 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.Sexy Mesh Transparent Female Running Tank Top with Hood Custom.

After 2 h, the solid was filtered using qualitative filter paper (Polyurethane Gasket Foam Seal Dispensing Machine).DVD Audio RCA Wiring Harness Cable for DVD Pioneer Avh(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%Black Steel ASTM A192 Seamless Pipe Sch1200C for 24 h. The sample was then treated with 1%China Excavator Radiator /Oil Radiator /Water Radiator Manufacture0C for 2 h. After this treatment,Canton Fair Galvanized Steel Aluminium Ibr Roof Sheet Roll Forming Making Machine.

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%Air Vent Diffuser Adjustbable Air Well and Jet Diffuser. 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.
