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

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%FTTB Wdm Optical Receiver with 2 Output / AGC FTTB Optical Node. 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.
