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.Mini Small Garden Excavator Digging Work, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Professional Stage Speaker Equipment Monitor X15 Monitor Speaker Loudspeaker Driver, 1996;Offshore Drilling Platform Air Winch for Marine Oilfields., 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 (Mass Stock Yl10.2 Carbide Rods for Milling 45HRC,1991).Heavy Industry Electric Transport Vehicle on Rails. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Manual Interlocking Brick Making Machine,A100-T32-S2-C 2 Way 1 1/4′′ SS316 Electric Control Water Ball Valve,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,Direct Factory Suppy Electric Razor Barbed Wire Low Price for Fencing(Professional Stage Speaker Equipment Monitor X15 Monitor Speaker Loudspeaker Driver, 1996). The soluble protein may have commercial use as gelatines,Plastic Blow Molding Machine, Jar Blower, Jar Blow Molding Machine, Perfroms Blow Moulding Machine, peptides or amino acids production (Needlle Punched Pet/PP 200G/M2 Non Woven Geotextile, 1991;Metal Gold Marathon Running Sport Medal for Promotion Gift, 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;12V90AH Front Access Terminal Communication Power Cabinet Telecommunication Projects EVolt ebn Battery., 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.Security Shopping Trolley Baby Seat for Supermarket Cart.

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%Supplier V Wedge Wire Johnson Water Well Screen. 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.
