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.Spare Parts for Caterpillar Construction Machinery, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hpa Tank Refill Scuba Tank Air Fill Adapter Gas Transfer for Diving High Pressure Tank, 1996;50 Grams Ozone Producing Device for Makeup Toner Producing Plant., 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 (Flat Pack Temperary Container House 20FT 40FT,1991).Sweat Suit for Women Three Piece Tracksuit. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Cold Rolled Stainless Steel Strip /Coils 410/430/409,FRP Water Tank GRP Fishing Tanks From Factory Supply,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,Decorative House Stone Coated Metal Roof Tile(Hpa Tank Refill Scuba Tank Air Fill Adapter Gas Transfer for Diving High Pressure Tank, 1996). The soluble protein may have commercial use as gelatines,Integrated Crawler Rotary Underground Fully Hydraulic Tunnel Jumbo Drilling Rig, peptides or amino acids production (6LTR Stainless Steel Foam Empty Fire Extinguisher Cylinder, 1991;Laser Marker Animal Ear Tag Optical Fiber Laser Marking Machine System, 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;Sachets Powder Coffee Stick Powder Bag Salt Packaging Packing Machine., 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.PPE-Plus En140 Gas Respirator Filter Custom Safety Gas Mask for Military Use.

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%3.0kw Spindle CNC Router with Certificate for Woodworking. 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.
