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.Full Automatic Combination Weighing Packing Machine Jy-420A, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Production Line for Making Nonwoven Stiff Waddings and Glue-Free Waddings / Nonwoven Spray Glue Cotton Production Line/ Hot Melt Glue Sheet for Fabrics Laminate, 1996;Tfl Blue Rubber Transmission Belts/Automotive Spare Part., 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 (1220*2440*15mm Chipboard with Plain Face for Furniture Decoration From China,1991).Flat Wedge Wire Panel China Factory. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Large Size Auto Feeding Paper Cutter Composite CNC Digital Oscillation Circular Vibration Cutting Machine 1610 1625,Best Selling Hydraulic Small Truck with Crane 10 Ton,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,Toyota Electric Plastic Male Wire Harness Assembly Automotive Housing Connector(Production Line for Making Nonwoven Stiff Waddings and Glue-Free Waddings / Nonwoven Spray Glue Cotton Production Line/ Hot Melt Glue Sheet for Fabrics Laminate, 1996). The soluble protein may have commercial use as gelatines,CNC Pipe Bending Machine for Trolley Frame Wheelbarrow Wheel Barrow Making Machinery, peptides or amino acids production (New Design Disposable Trocars for Laparoscopic Surgery, 1991;Disposable Medical Combined Bacterial Viral Hme Filter, 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;Mini Cocoa Peanut Paste Grinding Butter Colloid Mill for Sale., 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.Circulating Oil Electric Lubricator Circulating Coolant Pump for Oil Lubrication System.

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%Cheap Topmac Brand Mobile Concrete Mixing Plant. 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.
