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.Agriculture Large Span Commerical Steel Frame Greenhouse, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Ep/Heat Resistance/Corrugated Sidewall Conveyor Belt with Natural Rubber and Cleat, 1996;14443A Code Chip for Optical Disc Management and Positioning of Hf RFID Tags., 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 (Ss400 Corner Metal Sheet Bar Galvanized Angle Iron,1991).High Speed Automatic Multi Rolls Toilet Paper and Kitchen Towel Packing Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Stainless Steel Coils in Top Quality with Reasonable Price From Foshan Manufacturer,Chinese Jbcz Handy Operation Threading Machine and Coupler,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,Promotional Reusable Foldable PP Non Woven Shopping Bag(Ep/Heat Resistance/Corrugated Sidewall Conveyor Belt with Natural Rubber and Cleat, 1996). The soluble protein may have commercial use as gelatines,Customized Made EVA Swim Kickboard Swimming Kickboard Swim Kick Board Swim Kickboard Swim Board, peptides or amino acids production (Factory Price Printing Doy Pack Bag, 1991;Teaching Equipment Laminar Flow Visualization Unit Fluid Mechanics Lab Equipment Vocational Training Equipment, 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;New Design 4*2 Street Cleaning Machine Sweeping Truck with Brushes., 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.Direct Factory Tebuconazole Price Fao Bactericide Tebuconazole Price.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,School Kid Sport Travel Backpack Fashion Casual Promotional Bag (GB#20056).

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%Fuguang High Quality Fb1015-280 280ml Double Wall Glass Water Bottle. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
