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.Rectangular Stainless Steel Pipe SS304, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Efficiency Multistage Diesel Centrifugal Vane Pump for Chemical Industry, 1996;6.6kw LiFePO4 Charger for Lithium Battery Pack., 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 (Australian Merino Base Layer Ladies Wicking Breathable Anti-Odor Superfine Merino Wool Hoodie Pullovers,1991).50m Depth Long Range Metal Detector with Reliable Quality. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,CNC Router with Auto Tool Changer for Woodworking (XZ1325/1530/2030/2040),IP 44 Waterproof Indoor/Outdoor Aluminum Wall Mount 2-Way Column Speaker,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,Customized Stable Burn-in Test Equipment(High Efficiency Multistage Diesel Centrifugal Vane Pump for Chemical Industry, 1996). The soluble protein may have commercial use as gelatines,Wholesale Custom 100% Cotton Boys T-Shirt with Print, peptides or amino acids production (Industry 0.002mm Accuracy Checking Fixture, 1991;Promotional Customized PP Hand Fan, Plastic Folding Fan, 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;450mm 500mm Diamond Saw Blade with Good Sharpness for Reinforced Concrete Cutting., 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.Six Stations Pen Press 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%Agriculture Large Span Commerical Steel Frame Greenhouse. 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.
