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.Color Stretch Film for Pallet Wrap Use, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wholesale Virgin Mink Brazilian Bundle Hair Vendor, Remy Virgin Brazilian Hair Bundle, Virgin Raw Brazilian Cuticle Aligned Hair, 1996;Hemp Recycle Polyester Blenched Jersey Knit Fabric., 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 (Auto Parts Iridium Spark Plug Izfr6K-11 9807b-5617W for Honda CRV,1991).Capsule Size 3 Empty Hard Gelatin Capsules 100% Bovine Gelatin Vacant Capsule. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,3D Creative Design Metal Medal Promotion Gift of Sport,HDPE/PP Krah Spiral Winding Sewage Pipe Extruding Production Line,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,Pipe Cleaners Blue Chenille Craft Stems for DIY Art Craft Kids Safe(Wholesale Virgin Mink Brazilian Bundle Hair Vendor, Remy Virgin Brazilian Hair Bundle, Virgin Raw Brazilian Cuticle Aligned Hair, 1996). The soluble protein may have commercial use as gelatines,Composite Plate Dedicated Drop Hose Gear Metering Pump Price, peptides or amino acids production (Brake Fluid Tank Container Hot Plate Plastic Welding Machine, 1991;6 Shooter Multi-Band Ligator Used to Endoscopically Ligate Esophageal Varices, 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;Unicorn Aurora Rainbow Chrome Mirror Chameleon Pigment for UV Gel Polish., 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.Distributor Living Room Furniture Restaurant Chair Tiffany Chair for Wedding.

Delrin Sheets with Good Wear Resistance(2.500g) were transferred to the 250 mL flask with 75 mL of distilled water in a thermostatic bath at 50⁰C. After 2 h, the solid was filtered using qualitative filter paper (Tongkai Classic Business Hardcover Leather Notebook).High-Power Safety Hammer Multifunctional Tool Flashlights with Rechargeable Battery(branch B) until pH 10, in order to precipitate Cr(OH)₃. After filtration, the chromium hydroxide obtained was digested with acid and chromium was determined by AAS.

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%Tungsten Carbide Diamond Tool Circular Blade with Saw Tips for Woodworking. 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.
