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

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%10X20FT Outdoor Folding Pop up Marquee Canopy Gazebo Tent for Sale. 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

Medium Voltage 12kv/630A Indoor Sf6 Gas Insulated Switch Disconnector. 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.
