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.16mm 12 Strand UHMWPE Synthetic Fiber Rope, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Customized Detachable Grid Logistics Storage Industrial Racking Systems, 1996;Vertical Type Caseformer Machine WJ-LKX-15., 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 (Fb-5.0s 5.0-Inch Recorder Dual-Lens HD Night-Vision with Reversing-Image Integrated Machine,1991).Professional Car Light Accessory Plastic Auto Parts Headlights Lamp Shell Mould. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,0.1mm Tungsten Carbide 2f Single Flute Micro End Mill,Agriculture Large Span Commerical Steel Frame Greenhouse,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,Ep/Heat Resistance/Corrugated Sidewall Conveyor Belt with Natural Rubber and Cleat(High Quality Customized Detachable Grid Logistics Storage Industrial Racking Systems, 1996). The soluble protein may have commercial use as gelatines,14443A Code Chip for Optical Disc Management and Positioning of Hf RFID Tags, peptides or amino acids production (Ss400 Corner Metal Sheet Bar Galvanized Angle Iron, 1991;High Speed Automatic Multi Rolls Toilet Paper and Kitchen Towel Packing 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;Stainless Steel Coils in Top Quality with Reasonable Price From Foshan Manufacturer., 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.Chinese Jbcz Handy Operation Threading Machine and Coupler.

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%Pond Self Priming Booster suction  Water Pump with Pressure Switch. 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.
