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.Manufacturer for All Kinds of Bicycle Accessories/Motorcycle Parts by CNC Centre, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Engine Parts Suspension Control Arm OEM 54501-Jg00b, 1996;Spinning Spin Exercise Bike Fitness Equipment Cross Fit Elliptical Trainer Crosstrainer with Seat., 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 (Custom Anti UV Sun Protection Quick Dry Jacket Lightweight Windbreaker,1991).Sofiderm Best Selling Breast Enhancer Injectable Hyaluronic Acid Dermal Filler with Ce. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Common Housing Household Plastic Products Injection Moulding Making Machine Manufacturer,Fiber Laser Marking Machine for Aluminum Alloy, Copper, Iron, Metal Knife,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,Refillable Airless Cosmetic Packaging 10ml 15ml 20ml 30ml Serum Bottle(Engine Parts Suspension Control Arm OEM 54501-Jg00b, 1996). The soluble protein may have commercial use as gelatines,Customized Thickness EVA High Density Foam EVA Roll, peptides or amino acids production (Low Price Cmit/Mit14%/Chloromethyl-Isothiazolone as Bactericide/Fungicide, 1991;Carbide Mould Parts Moulding Parts, 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;Compression Mens Customized Gym Shorts Sportswear., 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.Hot Sale Prime Hot Dipped Galvanized Steel Coil/Band/Tape/Strip.

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%Multiple Style Jewelry Packaging Box/Ring Box Custom Logo Jewelry Box. 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.
