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.Customized Non-Standard CNC Machining Steel Mold Parts Wire Cuting Plastic Injection Mold Components, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Belt Conveyor Systmem for Fertilizer Production Line, 1996;Linear Motion Bearing Assembly Ballscrew 16mm Diameter Lead Screw with Double Nut Single Nut Promotion Price., 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 (Digger Spring for Excavator Machinery,1991).1.8ml Clear Sample Vials with Label and PP Caps. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Factory Small Coil Compression Spring in High Quality,Stainless Steel Movable Storage Tank for Cosmetics Chemicals with ASME Certificates,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,Premium Grade Export Best Price Organic Bulk Supply New Crop Hot Sale Pumpkin Kernel(Belt Conveyor Systmem for Fertilizer Production Line, 1996). The soluble protein may have commercial use as gelatines,Plastic Material Handling Dolly Platform Hand Trolley Truck, peptides or amino acids production (Transparent 43/410 Soap Dispenser Hand Wash Pump Foam Pump, 1991;Viscose and Polyester Blends Spunlace Nonwoven Fabric For Home Wipes, 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;99% Purity Serms Steroids Megestrol Acetate CAS 595-33-5., 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.ATV Spiked Chain Harrow for Farming.

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%C Purlin/C Steel Beam/ C Section Steel/ C Shaped Steel. 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.
