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.Basic Style Buffalo Leather Safety Shoes Ce Certificate S3 (SN1388), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Gamicos Wireless Diesel Fuel Fuel Oil Water Tank Level Gauge, 1996;Stainless Steel Ss304 Sanitary Hoop Union (ACE-HJ-G3)., 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 (Resistant Flame Retardant Fiberglass Cloth Aluminum Foil Tape,1991).Linear Guideway for CNC Machine as Components. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Yute High Tensile Flexible 10mm Fuel Hose for Generator Parts,40ton Double Girder Low-Headroom European Electric Wire Rope Hoist/Winch (BMG-40122mm5),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,Countersunk Head Self Drilling Screw Color Zinc Plated DIN7504r(Gamicos Wireless Diesel Fuel Fuel Oil Water Tank Level Gauge, 1996). The soluble protein may have commercial use as gelatines,Aluminum Dual USB Backup Battery 10000mAh LED Flashlight Power Bank 8000mAh with Torch, peptides or amino acids production (LED Stadium Light High-Mast Outdoor Lighting SMD Sport Lamp Playground Gym Square Football Basketball 300W, 1991;External Retaining Ring for Shaft, DIN471, D1400, 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;Good Use Kitchen Stainless Steel Spiral Scrubbing Scourer / Pot Scrubber., 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.Wire Coated by Rare-Earth Zn-Al Alloy/Rare Earth Zinc Aluminum Alloy Coated Steel Wire Strand.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Kh No Fried Automatic Potato Chips Making Machines.

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%Deep Hole Cylinder Boring Machine. 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.
