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.CNC Machinery Aluminum and ABS Mock up Prototypes, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Bsp 60° Male Cone Seat Carbon Steel Fittings, 1996;Soccer Field Artificial Grass Cutting Machine for Installation., 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 (Plastic Nylon Sheet with High Temperature,1991).PVC TPU Tr 2 Color Sole Injection Moulding Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Wholesale Six Patterns for Light 6in1 Sale Laser Grating Lens and Mirrors,Professional Melting (30kg-30000kg) Scrap Induction Heating Furnace for Iron/Steel/Gold/Silver/Aluminium etc,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,Corrugated Paper Honeycomb Core Board for Doors(Bsp 60° Male Cone Seat Carbon Steel Fittings, 1996). The soluble protein may have commercial use as gelatines,Home Depot Electric Fireplace with Deco Insert Gas Heaters Fan Modern Furniture, peptides or amino acids production (Wood Handle Carbon Steel Sickle S202, 1991;High Quality Custom Golden Colored Powder Pill Organizer, 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;Cooperate with Brand Companies High Intensity Safety Reflective Red Jacket., 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.Disposable Pipette Tip 40~200UL with Ce.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,High Quality 98% Feed Grade Betaine Anhydrous.

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%Rubber Diaphragm Seals HNBR EPDM Rubber Diaphragm in High Quality. 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.
