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.Top Furniture Hotel Dining Furniture Metal Hotel Table Chair, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Container House as Kinder Garden, Modular House as School, Container House for Clinic or Hospital, 1996;Machinery Parts Aeroplane Engine CNC Milling., 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 (Aws E7018 Low Carbon Steel Welding Electrode,1991).Best Price Graphite Electrode with 4 Tpi Nipple RP HP UHP 200-600mm for Smelting. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Electrical Bike Waterproof Power Connector,Liquor/Spirits/Vodka/Whisky/Rum/Water/Brandy/Xo/Wine Glass Bottle with Clear Glass,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,Painted G80 Cargo Lashing Chain with Hooks(Container House as Kinder Garden, Modular House as School, Container House for Clinic or Hospital, 1996). The soluble protein may have commercial use as gelatines,Custmoized High- Quality Decoration Mirror Stainless Steel Curtain Wall, peptides or amino acids production (Automatic Feeding Customized Multi Layers Shirts Cutting Machine, 1991;Finely Processed Anodized Aluminum 6063 7075 CNC Turning Parts, 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;Portable Powerful Charger with Dual Pd Charger and Type-C Charger., 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.Flexible Vj Rigid Shaft Coupling for Pipe Flange.

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%Cross Hex Flange Screw. 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 (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
