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.Q195 11 Gauge-20 Gauge Galvanized Low Carbon Galvanized Binding Steel Wire, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hot Selling Custom Sheet Metal Fabrication, 1996;15L Diesel Hardware Tools Shop Ultrasonic Cleaning Machine 360W Jp-060s., 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 (Powder Coating Paint Lines Systems for Factory /Plants,1991).USB LED Clock Fan USB-Powered Portable Fan with Clock, LED Light Display Real Time, Mini Goose Neck Fan for Laptop and PC. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Mini Pencil Tag with Lanyard (YS211),100% Latex Free Endotracheal Tube with PVC Material,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,Neodymium Magnet Pot Assembly with Strong Weight(Hot Selling Custom Sheet Metal Fabrication, 1996). The soluble protein may have commercial use as gelatines,Grid Tie Solar Home Power System 5kw 6kw 8kw on Grid Solar Energy System, peptides or amino acids production (China Manufacturer of Venlo PC or Venlo Glass Greenhouse, 1991;Artnet Node Artnet to DMX Controller, 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;6061, 6063, 6082, 6351 T6 Aluminum Hexagonal Bar with Holes., 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.Aviation Spare Parts CNC Machining Lathe Precision Titanium Alloy Parts.

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%High-Speed Automatic Tri-Sealing Zipper Vertical Bag Making 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.
