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.Hot Sale Pet Grooming Cat Slicker Brush Dog Pet Massage Comb, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Barb NPT Male Pipe Hose Fitting Adapter Jic Female Fitting, 1996;Toilet Roll Tissue Wrapping Machine with Auto - Counting., 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 (Heat Pump Food Cabinet Dog Food Pet Food Dryer Machine,1991).Orange Monofilament Fishing Tackle Nylon Fish Net. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Crushed Knitting Velvet Sofa Fabric Furniture Fabric (CD002),By6-8-200-L Automatic Doypack Premade Pouch Packing Machine,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,Diameter 1300mm Lifting Electro Magnet for Cast Iron(Barb NPT Male Pipe Hose Fitting Adapter Jic Female Fitting, 1996). The soluble protein may have commercial use as gelatines,High Purity Magnesium Metal Ingot/Pure Magnesium Alloy Ingot 99.98% 99.95%, peptides or amino acids production (Evaporator Finned Tube, 1991;Men Training Sportswear Collection Muscle T Shirt Function Vest Fitness Shirts Sport Tops Gym Activewear, 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;Winter Design Acrylic Beanie /Bobble Jacquard Hat with Flowers /Machine for Knitted Winter Cap with Embroidery Circular Hat Knitting Machine., 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.100%Polyester Spandex Hotel Chair Cover (DPH7022).

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%Forged Steel Pressure Sealed Bonnet Globe Valve. 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.
