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.Line Scan Uvss System Portable Under Vehicle Surveillance, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Folding Steel Manual Wheelchair with Chrome Frame, 1996;Piston Cooling Nozzle Valve Body Made of 45# 35# Carbon Steel., 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 (Fashion Style Lady Alloy Quartz Watch with Simple Dial,1991).Rooftop HVAC Packaged Units (RTU) Amrta Manufacture. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Waterproof IP67 Outdoor Plastic Box Enclosure Electronic Junction Box,Building Decoration Material Acrylic Dispersant for Coating,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,High Speed Plastic PE Single Wall Corrugated Hose Pipes Extruder Making Machine(Folding Steel Manual Wheelchair with Chrome Frame, 1996). The soluble protein may have commercial use as gelatines,Diamond Tools Continous Saw Blade Segment Bldes Turbo Saw Blades Brazed Welded Saw Blades, peptides or amino acids production (Factory Supply Straight Ball Joint Bearing 02b04, 1991;Wrinkle Effect Crease UV Drying Machine UV Curing System, 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;Lithium Polymer 3000mAh 634169-3s 11.1V High Quality Li-ion Battery Pack., 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.Best Pinpointer Metal Detector Hand Held Underground Gold Metal Detector.

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%High Quality Plastic Butterfly Valve UPVC DIN ANSI JIS Standard Wafer Worm Gear Butterfly Valve PVC Level Butterfly Valve for Water Supply. 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.
