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.Anti Slip Fabric/Anti Slip Non Woven Carpet Underlay Backing Fabric, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Q235 Q345 Hot Rolled Channel Steel, 1996;OEM Factory New Girls Nuts Crunch Cheap Price., 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 (Hsac Shac Linear Guideway,1991).Am/RF Glasses Tag Anti-Theft Optical Tag for Glasses. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Indoor LED Track Light (AP-TB30/AP-TB20/AP-TB10),Pure Water Cutting Head Assy for Waterjet Cutting 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,Kitchen Piece Multi-Function Rectangular Non-Slip Heat-Resistant Pad Coaster Cushion Tablecloth Table Silicone Table Mat(Q235 Q345 Hot Rolled Channel Steel, 1996). The soluble protein may have commercial use as gelatines,Latest Lace Fabric Design Logo Flag Embroidery Patch, peptides or amino acids production (China Economic Customized Design Steel Frame Farm Buildings Poultry Farm House for Chicken, 1991;High Pressure 2 1/2 Hose Crimper Machine From Kangmai Hydraulic, 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;Auto Parts Window Regulator Switch for Mercedes Benz 213 905 15 05., 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.New H Type Battery Cage System for Layer Chicken Farm.

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%Professional Manufacturer Stainless Steel Floor Grating. 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.
