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.Farm Machine Parts Spring Harrow Tines/ Fork Tedder Tines, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (2.0mm Pitch Pin Header SMT Type T Series Single Row Dual Housing B01, 1996;PRO-Installer Fiber Optic Termination Kit Lk-6016., 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 (Steel Scrap Iron Metal Copper Induction Melting Furnace Plant Foundry Furnace,1991).Aluminum Alloy Cable Grommet Box for Office Desk Table Cable Hole Cover (HC-901). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Best Polishing Pads Concrete Grinding Discs Diamond Sanding Discs,Powder Coated H Column Beam Steel Structure Building for Sale,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,Good Price Sc Single Mode Simplex Duplex Fiber Optic Adaptor(2.0mm Pitch Pin Header SMT Type T Series Single Row Dual Housing B01, 1996). The soluble protein may have commercial use as gelatines,Heat Pump Dryer Professional Equipment & High Capacity Dried Fruit Processing Machine, peptides or amino acids production (500ml/800ml Glassware/Glass Wine/Liquor/Spirits/Vodka Bottle Like Peanut, 1991;Nylon Cable Glands with CE, 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;X Shaped Extruded Aluminum Window Screen Frames., 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.Cuticle Aligned Raw Virgin Hair Easy to Dye Real Mink Brazilian Hair.

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%ISO Factory of Tunnelboring Machine Rolling Over Disc Cutter. 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.
