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.Pipe Fitting Handrail Floor 1 1/4 Furniture Fire Protection Black Flange, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cermet Circular Cold Saw Blade for Carbon Steels Cutting with Special Tooth Feature, 1996;Flow Wrapper/ Bakery Moon Cake Packing Machine., 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 (Full Automatic Liquid Filling; Machine; Oil Detergent Shampoo Disinfectant Bleaching Liquid Soap Cleaner Corrosive Filling Capping Labeling; Packing Machine,1991).Roll-up Heat Resistant Aluminum Mosquito Net 24X24 Window Screen Cover Wire Mesh. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Reusable Metal Stainless Steel Drinking Straws,Designed Steel Frame Factory Building,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,Detergent and Cosmetic Grade SLES/AES Sodium Lauryl Ether Sulfate(Cermet Circular Cold Saw Blade for Carbon Steels Cutting with Special Tooth Feature, 1996). The soluble protein may have commercial use as gelatines,0-10V Dimmable Double Side Recessed LED Linear Light for Meeting Room Office Table, peptides or amino acids production (Scouring Pads Making Machine for Brush King, 1991;Ideabond Stone Texture ACP Aluminum Composite Panel for Outdoor, 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;Glass Mix Stone Mosaic Tiles., 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.Wire Cutting Clamping Beam for Used Sodick Wire EDM Machine.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Stainless Steel Seamless Pipe ASTM A312 TP304 316.

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%Prime Quality ASTM A240 AISI 201 304 316L 321 310S 2b Finish Cold Rolled Stainless Steel Sheets From Tisco. 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.
