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.Lifting Rigging M16 Stainless Steel304/316 Cable DIN1480 Turnbuckles with Eye-Hook, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Flour Making Machine Wheat Maize Flour Mill Machinery, 1996;Hot Dipped Anti-Rust Galvanized Vertical Type Metal Chicks Rearing Cages for Laying Hens., 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 (Factory Direct Supply Yiwu Stocklots Hard Cover A5 High Quality Leather Notebooks for Gifts Free Shipping,1991).Ferrule Woven Rope Wire Mesh /SS316 Decorative Rope Mesh. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Integrated Wastewater Treatment Equipment for Poultry and Slaughtering Sewage Treatment,Metal Material and Sports Theme Custom Metal Medal,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,Portable Installation and Ce Certification 20g/Hr OEM Air Purifier(Flour Making Machine Wheat Maize Flour Mill Machinery, 1996). The soluble protein may have commercial use as gelatines,Water Treatment Alkali Chemicals Sodium Carbonate (Na2CO3), peptides or amino acids production (Full Computer Plain Socks Knitting Machine with High Quality, 1991;Common Code Choke, Inductor, Line Filter, Ring Coil, Inductor, Choke Coil, 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;New Style LiFePO4 Battery Powered Electric City E-Bike, Bicycle Moped with Pedals with 36V 250W Motor (JB-TDE23Z)., 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.One Step Myo/Ck-MB/Ctnl Combo Rapid Test Cassette.

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%Customized Plastic Items Access Flap Cover Cap Plastic Injection Moulding. 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.
