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.China Manufacturer Customized Microwave Ring Ferrite Magnet, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Paddle Brush Copper Needle Cushion Hair Care Comb Metal Pin Tan Mujiang-Fish, 1996;Competitive Price Good Quality Custom Unisex Marle Grey Fleece Hoody., 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 (Printing Adhesive Waterproof Custom Membrane Switch for Electric Cooker,1991).Electrical 4W AC Synchronous Gear Motor for Engraving Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Custom Car Seat Belt Buckle Mold Maker,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,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,Exfoliating Shower Hemp Bath Sponge Pad(Paddle Brush Copper Needle Cushion Hair Care Comb Metal Pin Tan Mujiang-Fish, 1996). The soluble protein may have commercial use as gelatines,Real Gold or Imitation Golden Color PVD Vacuum Plasma Ion Coating Machine for Watch, Jewelry, peptides or amino acids production (Wireless Optical Fire Smoke Detector with Solar Powered (ES-T601), 1991;Sequins Butterfly Handmade Beads Embroidery Patch, 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;Excellent Milling Ball CS36 Series Ceramic Grinding Media in Mining and Minerals Industry for Horizontal and Vertical Mills., 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.Fancy Hotel One Seat Fabric Hotel Molded Sofa Chinese Furniture Customization Upholstery for Hilton Hospitality Hotel Bedroom Furniture Luxury Supplier.

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%CO2 Glass Tube Ss Laser Marking Machine for Different Non Metal Marking Machine. 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.
