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.Polymeric Ferric Sulfate (SPFS/PFS) for Water Treatment, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Rht-060ws Soda Process Water Cooled Screw Type Water Chiller, 1996;Pressed Pipe Scaffold Clamp JIS Ks BS 48.6 Steel Double and Swivel Scaffolding Clamp., 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 (Boat Aluminum Pipe 5083 Marine Used Aluminum Tube,1991).Imirootree Wholesale Empty 100ml Amber Glass Cosmetic Jar. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2017 Year The Newest 7inch LCD Screen Advertising Brochure Video Greeting Cards,Cheap 100% Natural Brazilian Remy Cuticle Aligned Virgin Human Hair,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,Flanged Braided Metal Hose Connector(Rht-060ws Soda Process Water Cooled Screw Type Water Chiller, 1996). The soluble protein may have commercial use as gelatines,Timber Pressure Vessel for Wood Processing, peptides or amino acids production (1200mm Recessed Mounted LED Linear Light, 1991;The Big Diameter Carbide Tipped Hole Saw, 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;Promotional 16oz Pint Drinking Glass Mixing Glass with Letter Logo., 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.Tc/Sc/Tb/Sb Oil Seal Much Stock on Sale.

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%Deep Drawing Aluminum Circle /Disc for Cookwares 1050 1060 1100 3003. 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.
