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.7inch Desktop 1080P Media Player MP5 Car Monitor with AV Input, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Frozen Soybean in Pod, 1996;Custom Sheet Metal Stamping Bending Product Manufacturing Service., 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 (Waterproof EVA Rubber Roofing Material for Shingle Building,1991).OEM Gray Cast Iron Sand Casting Products with Universal Parts. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,U. S. Type Drop Forged Wire Rope Clip,Humizone Seaweed Customized Organic Liquid Fertilizer,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,Zipper Fabric Travel Passport Wallet Organiser(Frozen Soybean in Pod, 1996). The soluble protein may have commercial use as gelatines,Hot Sale Instax Mini Camera Korea Style Photo Album, peptides or amino acids production (Aluminum Low Profile Adjustable Bracket, 1991;Quality Assurance 6000W Inverter for Solar Panel 5kw/6kw Power Inverter, 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;High Quality Acrylic Beer Display Racks with LED., 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.Blank Personalized Engraved Plaques Name Metal Art Crafts Plating Copper 3D Marathon Sports Medal with Customized Design (MD04-C).

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%BOPP CPP Laminate Food Packaging Metalized Pet Cup Sealing Film. 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.
