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.3 Colors Tactical Shooting Hunting Camouflage Clothes Suit, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (1.3KG Fire breaker for kitchen, 1996;Ce RoHS FCC Shop Advertising Neon Illuminated LED Open Sign., 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 (Korean Integrated CTO Activated Carbon Filter for Water Treatment,1991).Vacuum Squeeze Filter Press for Coal Flotation Tailings. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Modular Portable Shipping Container Lkit Building Home Villa House,New Style 1000W Round Square Metal Tube Pipe Fiber Laser Cutting Machine for Stainless Steel Carbon Steel,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,China Supplier of Excavator Spare Parts for Caterpillar Cat330(1.3KG Fire breaker for kitchen, 1996). The soluble protein may have commercial use as gelatines,Auto Accessories 3D/5D/7D Hot Press Car Pads for Toyota Innova crystal, peptides or amino acids production (Aquarium Air Pump with 2 Nozzles Adjustable Gas Flow, 1991;Wheel-Type-Carriage Precision Heavy Duty Linear Guide, 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;Double-Offset Double Flanged Stainless Steel Butterfly Valve., 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.Automotive Acrylic Wholesale Masking Tape Factory Price.

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%Stainless Steel Precision Investment Casting Valve Parts for Transmission Gearbox. 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.
