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.Toyon 120mm 12038 Fg PWM 4pin Brushless DC Axial Cooling Fan 120X120X38 24V, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (10mm AISI304 Carbon Steel Balls Motor Bearing for Slide, 1996;Different Size of Ring NdFeB Magnet., 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 (Stainless Steel Investment Precision Casting for Valve Body with Machining,1991).Unique Best Quality Copper Home Alcohol Distiller for Sale. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Densen Customized China Transmission Shaft Coupling, Coupling of Agricultural Machinery Accessories,Hot Selling Fgg. 0b. 309 Metal Circular Push Pull Connector,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,Drive Travel Car Inflatable Bed(10mm AISI304 Carbon Steel Balls Motor Bearing for Slide, 1996). The soluble protein may have commercial use as gelatines,Custom 500ml Travel Mug Double Walled Vacuum Flask Water Bottle for Gift and Outdoors, peptides or amino acids production (China PCBA Supplier Custom Game Controller PCB, 1991;TPU TPR Rubber Band Plastic Extruder Machine, 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;Wheel Loader Transmission Gear Box/Customized Casting Parts., 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.SMT Mini Desktop Visual Chip Mounter Tp210+ (TORCH).

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Lw250*700 Spiral Discharge Decanter Separator for Water Treatment.

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%Single Cheap Custom Festival Woven RFID Fabric Wristband for Events. 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.
