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.Medium High Carbon Black Round Bicycle Wheel Spoke Tension Steel Wire, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Liquid Hardener Setting Cement Membrane Curing Concrete, 1996;Professional Silicone Rubber Gasket for Doors Windows., 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 (Top Quality 99.95% Molybdenum Square Plates,1991).HDPE Skew 45 Degree Drainage Pipe Fitting Sewage Tee. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Flat Face Stainless Steel Female Jic Quick Release Coupling,Aluminium Glass Dropper for Glass Dropper Bottle,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,L133pbd Common Rail Delphi Nozzle for Ford Mondeo(Liquid Hardener Setting Cement Membrane Curing Concrete, 1996). The soluble protein may have commercial use as gelatines,Pet PVC Shrink Label for Bottled Beverage Bottle Can Packing, peptides or amino acids production (Customerized OEM Matel Fabrication Agricultural Machinery Parts Harvester Parts, 1991;Automatic PS Foam Lunch Box Fast Food Container Tray Vacuum Forming 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;One Compartment Commercial Sink Without Drainboard., 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.Ge Holter Cable Snap Type Holter ECG Cable.

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%Hf Vacuum Dryer Machine for Drying Wood. 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.
