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.Metal Parts Stamping, Stamped Brass Shrapnel,   Brass Connect Stamping, Electronic Connection Piece Metal Stamped Part, Copper, Brass Connect Stamping, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Stacking Plastic Crystal Bar Stool Chiavari Napoloen Chair, 1996;Factory Direct Sale Custom Auto Refinish Paint Masking Tape/Crepe Paper Tape., 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 (Heavy Caliber Copper Rectangular Steel Tube,1991).2mm White Coated Paper Cake Boards Jordan. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Multiple Style Jewelry Packaging Box/Ring Box Custom Logo Jewelry Box,Luxious Hotel Passenger Elevator, Titanium Elevator,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,Yuchai 400kw Diesel Generator Set(High Quality Stacking Plastic Crystal Bar Stool Chiavari Napoloen Chair, 1996). The soluble protein may have commercial use as gelatines,Black Plastic GRP FRP PE Pipe Fitting for Water Supply, peptides or amino acids production (2194230012 for Mercedes Benz Auto Spare Parts Brake Disc, 1991;Precision Casting Factory Foundry OEM Ductile Iron Sand Casting, 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;Hot Sale Electrical Motors Small for Home Appliance., 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.PE PVC Profile Extruder PE PP Profile Extrusion Machine Plastic Profile Extrusion Line.

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%Delphi Control Valve 28239295 (622B). 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.

CONCLUSIONS

Air-Cooled Induction Heater for Metal Heating Brazing Welding Hardening Tempering. Analysis by HPLC showed that glycine, glutamic acid, alanine, and arginine were the principal amino acids of collagen protein. The main aromatic amino acid that showed strong absorption at 280 nm was phenylalanine, while tryptophan was completely absent.
