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.Quality Assured Magnetic Building Blocks for Children, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Factory Price Lawn Sprinkler Portable Sprinkler Irrigation System, 1996;Heavy Duty Industrial Biodegradable Plastic Garbage Bag Black/Gary., 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 (Punching Machine for Greenhouses Quilt Raw Materials Heat Preservation Warm Keeping Quilt Making Machine,1991).Cameleon Color Changing Car Paint Chameleon Pigment for Auto Paint. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Cummins L10 Engine Piston Cooling Nozzle 3070218,Access control custom printed 13.56MHz PVC Smart FUDAN FM32 blank RFID Card,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,Glass Wool Sandwich Panel Metal Roof Price/Glass Wool Board(Factory Price Lawn Sprinkler Portable Sprinkler Irrigation System, 1996). The soluble protein may have commercial use as gelatines,SMT E2 Type Air Coils Inductors Inductance Range 5.0∽ 60.0nh E2r230-10.3nj for Ssb Radio Equipment Use, peptides or amino acids production (99% Al2O3 High Alumina Ceramic Ball, 1991;Factory Price Long Life Portable Peltier Air Cooler, 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;8W/12W Dimmable Interior Ceiling LED Recessed/Flush Can/Spot Down Lights for Museum/Salon/Club., 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.Hand Tools 9PCS Hex Key Set CRV Allen Wrench.

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%Crop Top Vest Fitness Drawstring Padded Gym Women Sleeveless Tank Sport Clothing. 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

Low Noise Ventilating Blower Fan for Agriculture. 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.
