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.Soft Rubber Hair Remover Pet Brush, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Forging Metal Building Parts, 1996;Sinbosen Professional Stereo Amplifier Fp20000q Best Power AMPS for Live Sound., 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 (Safety Traffic Rubber Roof Support Feet Products,1991).Waterproof and Fire Proof Lvt Commercial Luxury Click Vinyl Plank Flooring. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Waste Water Treatment and Sewage Treatment Plant with Mbr/ Mbbr Technology,Table Planetary Saw Blade Alloy Steel Pipe Tube Cold Cuter,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,Weaving Poly Wicker Cookeware Gas Fireplace Rattan Fire Pit Table Set Furniture(Forging Metal Building Parts, 1996). The soluble protein may have commercial use as gelatines,China Supplier Solar LED Street Light Price Ce RoHS (SX-TYN-LD-15), peptides or amino acids production (Fresnel Lens for Pyroelectric PIR Infrared Radial Sensor, 1991;Rubber Tire Plastic Recycling Shredder with Factory Price, 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;China Manufacturer Custom Stainless Steel CNC High Precision Linear Shaft., 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.Dog Bone Rubber Patio Paver Tile/Ourdoor Rubber Driveway Rubber Tile.

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%Paper or PVC Mobile or Cellphone Scratch Recharge Prepaid Card. 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.
