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.Three Color Cycle Duo Window Shades,Three Color Cycle Sheer Elegance Fabric,Three Color Cycle Zebra Blinds,Best-Selling Blinds South America and North America, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Luxury Retail Carrier Bags for Shopping Shoes Garments Cosmetic Gifts Packaging/ Paper Handle Bags, 1996;Rubber O Rings Rubber Products Rubber Parts Rubber Oring Seals and Gaskets., 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 (Australia Two Pins Power Cord with SAA Certification,1991).87000kpsi Waterjet Intensifier Parst HP Ceramic Plunger. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Professional Supplier of Aluminium Sulphate Non Ferric 16%-17%,Plastic Vegetable Plants Support Netting Green Trellis Mesh / Creeper Plant Support Net,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,Commercial Gym Fitness Equipment Hammer Strength Half Rack Power Cage(Luxury Retail Carrier Bags for Shopping Shoes Garments Cosmetic Gifts Packaging/ Paper Handle Bags, 1996). The soluble protein may have commercial use as gelatines,Frosted Black Glass Aromatherapy Bottle Reed Diffuser Perfume Bottle 50/110/230ml, peptides or amino acids production (Pickled Cucumber Production Line/Making Machine, 1991;Rectangular Lunch Tin Box with Handle, 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;Inflatable Cheering Stick for Promotional Gift., 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.Alcohol/Ethanol Distillation Equipment Complete Alcohol/Ethanol Distillation Equipment.

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%Wall Mounting Metal Control Box Control Desk. 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.
