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.Electrical 4W AC Synchronous Gear Motor for Engraving Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Custom Car Seat Belt Buckle Mold Maker, 1996;DIN/ANSI/JIS/API Stainless Steel CF8/CF8m Wafer Type Butterfly Valve for Pn10/Pn16 or 10K/16K or Class150/300/600 for Sanitaty/Oil/Gas/Water., 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 (Exfoliating Shower Hemp Bath Sponge Pad,1991).Real Gold or Imitation Golden Color PVD Vacuum Plasma Ion Coating Machine for Watch, Jewelry. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Wireless Optical Fire Smoke Detector with Solar Powered (ES-T601),Sequins Butterfly Handmade Beads Embroidery Patch,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,Excellent Milling Ball CS36 Series Ceramic Grinding Media in Mining and Minerals Industry for Horizontal and Vertical Mills(Custom Car Seat Belt Buckle Mold Maker, 1996). The soluble protein may have commercial use as gelatines,Fancy Hotel One Seat Fabric Hotel Molded Sofa Chinese Furniture Customization Upholstery for Hilton Hospitality Hotel Bedroom Furniture Luxury Supplier, peptides or amino acids production (Adjustable Aluminum Solar Mounting System, 1991;Wholesale Wireless Cheapest Android 2D Barcode Scanner, 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;Factory Price Diamond Wire Mesh Chain Link Fence., 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.Electric Heating Mantle 5L.

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%Women′s Tote Bag Small Canvas Shoulder Bag Daily Working Handbag. 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.
