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.Automatic Drinking Mineral Water Filling Line/Water Bottling Line, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Newest Design Factory Price Brown Leather School Bag Genuine Leather Backpack for Men, 1996;PP Polypropylene Two Layer Film Blowing Machine., 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 (Disposable Sugarcane Pulp Paper Bowl 500ml,1991).Flat Roof Insulation Board Heat Insulation Board. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2018 Single-Sided Printing Ribbon Bow Ribbon Gift Wrapping Ribbon,Custom Female Threaded Tee T Shape Pipe Fittings,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,Wholesale Soft Hallux Valgus Bunion Corrector Brace for Sport Protection(Newest Design Factory Price Brown Leather School Bag Genuine Leather Backpack for Men, 1996). The soluble protein may have commercial use as gelatines,Automatic Bagging Liquid Sauce Sachet Water Filling Sealing Machine, peptides or amino acids production (Solar Power Panels Kits Modules Home Solar System USB Fan Bluetooth Music Speaker, 1991;304 Stainless Steel Chocolate Pump for Delivering Chocolate Paste, 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;Toko 1.0mm Er70s-6 MIG Copper Alloy Welding Wire in Spools., 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.8.0g Polyester / Fiberglass Laid Scrim for Building - Tunnel Membranes.

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%Disposable Sterile Safety Blood Lancet. 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.
