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.2L 3L 5L HDPE Bottle Automatic Blow Moulding Machinery, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Fully Automatic Digital Pid Temperature Controller, 1996;High Quality Anti-Corrosion Fiberglass Sheet and Roll., 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 (Wholesale Bakeware Metal Stainless Steel Blade Pasta & Pastry Cutter,1991).Full-Automatic Folding Napkin Paper Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Customized Frame Mount Highway Pegs Enclosure Parts,Tumble Rubber Belt Shot Blasting Machines Blast Machine for Descaling,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,10mm Tempered Bathroom Glass Safety Glass for Building(Fully Automatic Digital Pid Temperature Controller, 1996). The soluble protein may have commercial use as gelatines,3 Thickness HVAC Egg Crate Grille Aluminum Egg Crate Sheet, peptides or amino acids production (Cattle Feed Factory Used Dust Collector and Filter, 1991;Custom Clear Foldable Printing PP/PVC/Pet Plastic Packaging Box, 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;Group 152cm Picnic Folding in Half Table., 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.Tactile Custom Branded Membrane Switch Keyboard with Foil.

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%Hospital ICU Portable Electric Injection Syringe Pump Ce ISO Approval. 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.
