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.


Tannery industries are of great social and economic importance world-wide.Agriculture Plastic Film Polycarbonate Metal Prefab Greenhouse, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Q235 Jr Hollow Structual Section Steel Tubes with Good Quanlity, 1996;H2309 H2310 H2311 H2312 H2313 H2314 H2315 H2316 (H2317 H2318 H2319 HE211)., 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 (Custom Orange Color Delrin Sheet POM Board for Automobile Industry/POM Sheet/POM Rod/Acetal Rod/Delrin Sheet/Delrin Rod/Blue Delrin Sheet/Color Delrin Sheet,1991).High Quality Crusher for Used Plastic Recycling Line.

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,Wear Resitant Rope End Cap Plastic Flange Cover(Q235 Jr Hollow Structual Section Steel Tubes with Good Quanlity, 1996). The soluble protein may have commercial use as gelatines,Comfortable Two Piece Women Fitness Clothing for Gym Wear, peptides or amino acids production (Industrial Ultrasonic Cleaning Machine Rinsing Drying Function Muti Tanks Ultrasonic Cleaner, 1991;Flat Surface Mounted 300mm 24W LED Panel Light for Interior, 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;Latex Paint Emulsion Thickener Agents with High Leveling Property., 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.Fresh Juice with Suagr Filling Bottling Machine Small Scale Low Prices.

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%Glass Manufacturer/Float Glass/ Tempered Glass (Flat or Curved) for Building / Furniture. 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.
