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.Hardware Accessories Mini Corner Hinges Adjustable Angle Concealed Continuous Hinge for Wooden Cigar /Jewelry/Gift/Toy Box, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Efficiency Indoor Dust Sweeper Floor Easy Flat Mop, 1996;Precision Customized CNC Machined Mild Steel Flange for Automobile., 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 (Professional Sensitive Relief, Cnice Brand Toothpaste with Oral Refreshing,1991).Metal Container Packaging for Edible Oil Tin Cans Storage Boxes. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Melee Custom Plastic Mould New Design,High Efficiency Pure Sine Wave DC12V AC220V 1500W Power Inverter,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,Copper-Pressed V-Type Expansion Pipe Joint(High Efficiency Indoor Dust Sweeper Floor Easy Flat Mop, 1996). The soluble protein may have commercial use as gelatines,Green Nylon Sponge Scouring Pad Kitchen Cleaning Sponge Scrubber, peptides or amino acids production (White Desiccant Bag Silica Gel with Indicated Orange Bead, 1991;High Quality Iron Wire Mesh Chain Link Mesh Security 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;TUV Certificate Passed Low Cold Area in -25 Degree Evi Air to Water Heat Pump., 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.5% off Sale Price Rutile and Anatase TiO2 Titanium Dioxide.

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%Roller Skating Sneakers Shoes for Children (8083). 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.

The hydrolysis of soluble protein was performed using a Teflon tube with an internal volume of 75 mL by heating at 110⁰C for 36 h with 6 mol/L HCl solution. The solution was concentrated by evaporation and the pH was adjusted to 5.0 - 5.5.40X-1600X Biological Microscope Xsz-107V LED Light⁰C (flow rate 0.3 mL/min.). Ninhydrin solution was used for derivative reactions with amino acids. The eluents used were: mobile phase A: buffer solution of 0.2 mol/6063 Aluminum Coil for Commercial Vehicle Floor, pH 3.25., mobile phase B: buffer solution of 0.01 mol/Silicon Carbide Foundry Porous Ceramic Foam Filter, pH 7.40. Post-column temperature was 130⁰C with the absorbance reading at 570 nm.
