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.Food Machine Cube Ice Machine for Commercial Use, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Christmas Decoration Rose Flower LED Light String, 1996;D Section Stainless Steel Tube., 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 (Mint Flavor 50ml Home Foam Toothpaste,1991).125mmsintered Dry Cutter Turbo Diamond Circular Saw Blade for Tile. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Dxz Limit Switch Tower Crane Spare Parts,OEM/ODM Price Top Open Keypad Safe with Electronic Code Lock,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,High-End Business Magnet Leather Ring Binder Notebook(Christmas Decoration Rose Flower LED Light String, 1996). The soluble protein may have commercial use as gelatines,Disposable Nonwoven 3ply Medical Surgical Hospital Face Mask with Earloops, peptides or amino acids production (New Design Fashion Jewelry 925 Sterling Silver Shell Pearl Clavicle Chain Necklace Bar Necklace, 1991;Eyes- Caring LED Night Light for Nursing Reading with Soft Light, 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;China Bearing with Housing Bearing / Pillow Block Bearing., 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.Steel & Plastic Drums Lifters, Drum Lifters Handling Equipment Lm800.

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%Small Laser Cutting Engraving Machine ABS PVC MDF Engraver Cutter. 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.
