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.White 4*8FT 18mm PVC Foam Board for Cabinets Use, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cationic 400d Jacquard Polyester Oxford Sofa Fabric with PU Coating, 1996;Transparency Chandelier Glass Crystals Lamp Hanging Drops Pendants., 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 (Powerful Anti-Stress, Strong Flexibility Spoke Wire,1991).Modern American Style Beech Solid Wood Kitchen Cabinet. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Hero Brand Polypropylene Bags Machine,CNC Machining Metal/Aluminum/Brass Auto Parts,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,Surprise! Range Hood Free! ! ! Juice Cart(Cationic 400d Jacquard Polyester Oxford Sofa Fabric with PU Coating, 1996). The soluble protein may have commercial use as gelatines,Chicken Layer Cage Poultry Cage Chicken Cages, peptides or amino acids production (316L Cold Rolled Stainless Steel Coil 316L Inox, 1991;Delphi 2 Pin Male and Connector Custom Harness, Wire Diameter 18AWG, 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;Fully Automatic C Z Purlin Cold Roll Forming Machinery., 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.Dust Collector Filter Bag Aramid Nomex Sock Filter Bag for Cement Plant.

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%Double Wine Carrier Bag Gift Box Tote. 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.
