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.Glass Lifting Machine with Sucker for Glass Movements, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Anodized Gold Brush Finish Aluminum Sheet Coil, 1996;Popular Industrial Sewing Quilting Machine With CO., 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 (Chinese Manufacturer Provide First-Class Service for Non Stretch/Elastic Allover Lace,1991).Alloy 6061 T4 T6 T651 Aluminum / Aluminium Plate. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Pure Sine Wave Power Frequency Inverter,Copy Paper Writing Paper Newspaper Toilet Paper Tissue Paper Kraft Paper A3A4 Paper Corrugated Paper Facial Paper White Board Paper Wrapping Paper Machine,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,Colorful 100% Cotton Hotel Face Towels(Anodized Gold Brush Finish Aluminum Sheet Coil, 1996). The soluble protein may have commercial use as gelatines,High Quality Electric Folding or Curving Bender 3D CNC Hydraulic Bneder Automatic Pipe Bending Machine Used for Furniture and Chairs (GM-SB-76CNC-2A-1S), peptides or amino acids production (33kv Dry Type Resin Casted Distribution Transformer, 1991;Huaxia PAR56 Color Changing Swimming Pool Light Bulb LED Fixture Pool Used E27 Compatible with E26 with Remote Control Hx-PAR56-E27, 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;Economic and Reliable P32 Hydraulic Hose Crimping Machine Italy with SGS Certificate., 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.Size 000 Clear Pullulan Vegetarian Capsules.

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%Yute High Tensile Flexible 10mm Fuel Hose for Generator Parts. 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.
