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.Ribbon Mixer Plough Shear Mixer V-Shape Mixer Powder Mixer for Mixing Powder or Liquids, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Engine Starter Motor for Honda Cr-V 2.4L L4 2002-06 (Lester17844), 1996;Antique Stackable Metal Tiffany Hotel Event Hall Chiavari Banquet Church Chair., 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 (Single Block Vertical Wire Drawing Machine for Screw and Bolt Making,1991).High Chrome Hsi Crusher Parts Blow Bar Suit Terex Impact Crusher. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,China Electric PCB Circuit Board with High Quality,OEM Custom Forged Auto Parts, Precise Lost Wax Die Casting and CNC Machined Alloy /Aluminum/Zinc /Brass Forklift Truck Parts,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,Anodized Perforated 3D Facade Windows Screen for Commercial Building(Engine Starter Motor for Honda Cr-V 2.4L L4 2002-06 (Lester17844), 1996). The soluble protein may have commercial use as gelatines,Full Cream Milk Powder Filling Machine (XFF-G), peptides or amino acids production (Handmade Paper 3D Quilling Greeting Cards Quilling Birthday Cards., 1991;Dnv 271 En 12079 3.5 Cbm Offshore Mud Skip, 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;High Quality Wc67K 40 Ton 80 125t 2500 2.5m Metal Sheet Plate Construction Industry Hydraulic Small Mini CNC Bending Press Brake Machine Factory Price 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.Digital Printed 3D Carpet, Anti-Slip Hot Sale Floor Mat.

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%Seaflo 12V 0.7gpm/70psi Mini Electric Garden Pump. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
