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.Environmental Tester CCT Salt Fog Spray Cyclic Corrosion Test Cabinets, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Fingerprint Door Lock Smart Lock Padlock Hi-Tech for Door Security, 1996;Custom Logo Resealable Zipper Standing Pouch Food Snack Plastic Packing Bag with Hang Hole., 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 (Atf-805 Auto Car Transmission System Flushing Machine with SGS/Ce Approval,1991).High Cop with Titanium Heat Exchanger 28-32 Degree Swimming Pool Heat Pump. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,10 M City Bus Benz Chassis Birkom Shock Absorber Maintain Spare Parts Damper,300ton/H Mobile Sub Base Soil Mixing Plant for Road Construction,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,BS 5163 Ductile Iron Rising Stem Gate Valve(Fingerprint Door Lock Smart Lock Padlock Hi-Tech for Door Security, 1996). The soluble protein may have commercial use as gelatines,CNC Aluminum Sheet Press Brake, peptides or amino acids production (ID25mm Od86mm Standard Through Hole Slip Ring, 1991;Rigid Click Plank PVC Spc Vinyl Flooring Plank with IXPE Padding, 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;Bio Media., 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.Wood Sawdust Powder Gas Flow Dryer Sawdust Drying Machine.

Powerful Anti-Stress, Strong Flexibility Spoke Wire(2.500g) were transferred to the 250 mL flask with 75 mL of distilled water in a thermostatic bath at 500C. After 2 h, the solid was filtered using qualitative filter paper (Maleic Anhydride CAS 108-31-6).Modern American Style Beech Solid Wood Kitchen Cabinet(branch B) until pH 10, in order to precipitate Cr(OH)3. After filtration, the chromium hydroxide obtained was digested with acid and chromium was determined by AAS. The solid residue (branch A) was treated with 3% magnesium oxide (w/v) and 10%Hero Brand Polypropylene Bags Machine0C for 24 h. The sample was then treated with 1%CNC Machining Metal/Aluminum/Brass Auto Parts0C for 2 h. After this treatment,Surprise! Range Hood Free! ! ! Juice Cart.

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%Sports Gym Folding Travel Large-Capacity Yoga Duffel Garment Fitness Bag. 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.
