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.Ceramic Bearing Si3n4 608, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Nbm High Quality Auto Part Factory Price 6pk2310, 1996;Tk 4100, Em 4200, Em 4305, T5577 Lw 125kHz RFID Samrt Card PVC Inlay., 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 (High Quality Mini LED Flood Light SMD Flood Light 50W,1991).Compatible Datex Ohmeda 545307/545302 ECG Trunk Cable for 3-Lead. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Creative Rainbow Goblet Colored Electric-Plating Rainbow Red Wine Glass,Professional Manufacture Metal Medal Promotional Gift,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,Jqx-59f Wholesale Operate Time 25ms 12V Power Relay for Energy-Saving(Nbm High Quality Auto Part Factory Price 6pk2310, 1996). The soluble protein may have commercial use as gelatines,Singlemode Su Upc Fiber Optic Fast Connector, peptides or amino acids production (Roller Skating Sneakers Shoes for Children (8083), 1991;Food Grade Beer/Juice Treatment Bag Mamachine SUS304 316L Stainless Steel Bag Filter Vessel with Ss Removable Frame Holder, 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;Electric Heating Industrial Jacketed Glass Reactor., 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.40X-1600X Biological Microscope Xsz-107V LED Light.

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%Anti Slip Fabric/Anti Slip Non Woven Carpet Underlay Backing Fabric. 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.
