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.Nitinol Disposable Guide Wire, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Breathable Surgical Paper Tape/ Micropore Medical Tape, 1996;Fashion Wool Felt Lady Cloche Wide Brim Floppy Hat with Felt Bow., 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 (Crane Hook Qtz250 (7032) with 70m Jib Length,1991).China Manufacturer Price Home 24V 250W Mono Poly PV Solar Cell Panel for Solar System. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Emsco F-800 4 I40HK14/15 Mud Pump Piston for Bomco/Gardnerdenver/Hh/Ideco/Ls/National/Oilwell/Nov/Mudking/Southwest,Diesel Truck Engine Parts 3306 Turbocharger for Caterpillar,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,Online High Sensitivity Checkweigher with Pusher Bar(Breathable Surgical Paper Tape/ Micropore Medical Tape, 1996). The soluble protein may have commercial use as gelatines,Piggery Farm Pig/Sow Gestation Equipment From China Factory, peptides or amino acids production (Lw250*700 Spiral Discharge Decanter Separator for Water Treatment, 1991;Single Cheap Custom Festival Woven RFID Fabric Wristband for Events, 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;Children Gift Outdoor Wooden Rocking Horse Toy., 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.Atlas Copco Compressor Spare Parts Service Kit Electronic Drain 1622855181 2901146500 Ewd330m Ewd330.

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%Advanced Unlocking Tool for Locksmith. 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.
