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.Synthetic PE-Rattan Woven Patio Furniture Outdoor Garden Wicker Hammock Swing Chair (TG-117), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Sx Sm Fiber Optic MPO to MPO Adapter with Flange Type, 1996;Laptop Bag College Men Backpack Leather Back Pack Bags., 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 (Pet Dog Grooming Rake Dematting Tool Shedding Comb,1991).Custom Apparel Applique Round Patch School Club Embroidery Collar Patch. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Farm Tools and Equipment 7ton Backhoe Loader Construction Machinery,CT201795 Cartridge Chip for Xerox Docucentre IV 2056 2058,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,Anti Fog Shower Shaving Modern Bathroom LED Customized Mirror(Sx Sm Fiber Optic MPO to MPO Adapter with Flange Type, 1996). The soluble protein may have commercial use as gelatines,Automatic Food Metal Detector Machine for Production Line, peptides or amino acids production (Multi-Functional Backpack Manual 52cc Brush Cutter, 1991;Modern Living Room Furniture Hotel Bedroom Custom Corner Sofa, 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;Automatic Linear 5 Gallon Barrel Bottle Water Filling 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.Hipower Top 10 Speakers Professional Audio PA Loudspeaker 8ohm.

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%Stainless Steel Screens / Wedge Wire Filter Element. 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.
