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.100%Polyester Satin Fabric for Blouse, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Shenzhen Manufacturer High Quality Metal CNC Precision Machining Titanium/Stainless Steel/Brass Custom Aluminum Case/Box/Casing/Enclosure, 1996;Tungsten Carbide Extension Adapter Boring Bars for External Turning Tools., 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 (High-End Compression Rash Guards, Long Sleeve Compression Shirt,1991).High Quality 100% Cotton Printing Blank Short Sleeve T Shirt Hoodie with Your Logo. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Wear Resistant PVC Plastic Vinyl Plank Commercial Flooring for Office,Starry Laser Holographic Nail Glitter Powder Copper Shining Glitters,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,9~12 Inch Mechanical Backing Plate(Shenzhen Manufacturer High Quality Metal CNC Precision Machining Titanium/Stainless Steel/Brass Custom Aluminum Case/Box/Casing/Enclosure, 1996). The soluble protein may have commercial use as gelatines,DIN929 Low-Cost Supply Hexagon Weld Nut, peptides or amino acids production (Decoration Coil for 1000 Series Alloy 2mm Thick Aluminum Coil Thick Aluminium Aluminum, 1991;High Efficiency Solar Cell Photovoltaic 300W Hot Sell, 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;60m3/H Lamella Clarifier for River Water Treatment., 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.SGS Steel Lab Acid and Alkali Resistance Fume Hood Laboratory Furniture with Ce Certification (JH-FC019).

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%Galvanized Hexagonal Wire Mesh Gabion / Gabion Box. 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.
