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.Common Housing Household Plastic Products Injection Moulding Making Machine Manufacturer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Fiber Laser Marking Machine for Aluminum Alloy, Copper, Iron, Metal Knife, 1996;Refillable Airless Cosmetic Packaging 10ml 15ml 20ml 30ml Serum Bottle., 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 (Customized Thickness EVA High Density Foam EVA Roll,1991).Low Price Cmit/Mit14%/Chloromethyl-Isothiazolone as Bactericide/Fungicide. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Carbide Mould Parts Moulding Parts,Compression Mens Customized Gym Shorts Sportswear,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,Hot Sale Prime Hot Dipped Galvanized Steel Coil/Band/Tape/Strip(Fiber Laser Marking Machine for Aluminum Alloy, Copper, Iron, Metal Knife, 1996). The soluble protein may have commercial use as gelatines,99.8% High Aluminium Oxide Low Na2o Calcined Alumina Powder, peptides or amino acids production (Plastic Anti-Static PMMA Transparent Coated Lenses Sheet Making Machine Extruder, 1991;P10 P16 P20 DIP Full Front Service Waterproof LED Panel Display, 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;Electric Furniture Lift., 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.Roller Shutter Slat and Panel Manufacturer and Complete Roller Shutter.

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%Precision Casting Factory Foundry OEM Ductile Iron Sand Casting. 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.
