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.Bianco Carrara Marble, Italy White Stone Marble for Slabs, Tiles, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Rugged Construction Material for Steel Screens for Platforms and Floor Channels., 1996;FKM Rubber Gasket/Rubber O Rings in China., 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 (Inclined Waste Water Treatment Lamella Clarifier,1991).33kv 100kVA Dry-Type Distribution Transformer. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Fruit/ Vegetable Double Spray High Pressure Cleaner for Sale,Fine 36 Hydraulic Breaker Seal Kit for Fine 36 Hydraulic Hammer Seal Kit Fine 36 Breaker Seal Kit,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,5mm Spc Vinyl Planks Click Lock Floor PVC Plastic Laminate Flooring(Rugged Construction Material for Steel Screens for Platforms and Floor Channels., 1996). The soluble protein may have commercial use as gelatines,Suoer 12V 220V 3000W Pure Sine Wave Inverter (FPC-D3000A), peptides or amino acids production (Rimmed 1 2 5 10 15 20 25 Micron Circular Stainless Steel Filter Disc , 1991;China Manufacturer Export Copper Foot Tap/Valve (HFV-001), 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;Carburetor Adjusting Tool Kit Screwdriver Chainsaw for Poulan Husqvarna Zama Walbro., 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.PVC Corrugated or Smooth Surface Helix Suction Water Hose.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,CPVC ASTM2846 Water Supply Pipe Fittings Cross (G23).

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%Air Plasma Cutter Lgk100/CNC Plasma Pipe Cutting Machine/Plazma Cutting Machine. 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.
