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.OEM Factory/Chrome Steel/ISO Certificate/Used in Machine/Pillow Block Bearings/Bearings/Bearing (UCP), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Ms Gi Pipe Dn15~Dn400 Gi Pipe List, 1996;Low-E Insulating Glass Curtain Wall., 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 (Endoscopic Clip Applier Single Action Laparoscopic Applicator Instrument Forceps 5mm L1024,1991).Custom Logo Man Quartz Watch Fashion Wrist Watches for Men (WY-17016D). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Fashion Design Underwear for Men Cotton Mens Boxer Briefs,Nylon Balance Bike with Water Transfer Printing Malaysia,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,Anti Slip Rubber Mat(Ms Gi Pipe Dn15~Dn400 Gi Pipe List, 1996). The soluble protein may have commercial use as gelatines,5ml 10ml Mini Amber Blue Green Glass Essential Oil Bottle with European Dropper Cap, peptides or amino acids production (Electric 510mm Bar Length Dual Action Blade Handy Hedge Cutter Trimmer Fot Tractor, 1991;Pre Bonded U V I Flat Tip Hair Extension 1g Stick Tip Virgin Cuticle Aligned Remy Keratin Human Hair, 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;Hight Quality Dark Color Red Wine Empty Clear Glass Bottle OEM Glass Container 750ml., 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.Medium Voltage 12kv/630A Indoor Sf6 Gas Insulated Switch Disconnector.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Cold Rolled 0.3-3mm 310 310S Stainless Steel Sheet.
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%Rd 10 Portable Air Operated Double Stainless Steel Diaphragm Pump. 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.
