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.High Quality Silicone Reusable Food Storage Bag China Manufacturer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Polyurethane Gasket Foam Seal Dispensing Machine, 1996;Imee Print Customized Printing Agenda Printing Nb21., 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 (Aluminum Airless Bottle for Cosmetics Pump Bottle&Spray Bottle 15ml30ml50ml100ml,1991).High Performance Multifunctional Crawler Mini Skid Steer Loader. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Finks 41 Inch Koreanpine Sapele Single Solid Folk & Acoustic Guitar,Chunke Portable UV Water Sterilizer for Water Purifier 150t,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,Long Sleeve Lace Beaded Muslim Bridal Gown Wedding Dress(Polyurethane Gasket Foam Seal Dispensing Machine, 1996). The soluble protein may have commercial use as gelatines,Stainless Steel Swimming Pool Water Curtain Gardening Outdoor Wall Fountain, peptides or amino acids production (Xjm Series Rubber Extruding Machine, 1991;Stop Dog From Jumping or Climbing Your Chain Link Fence., 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;SGS Direct Thermal Label for Supermarket., 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.Water Filter Polyester Non-Woven Fabric.

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%Medical Supply U40 Disposable Insulin Syringe. 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.
