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.Deep Hole Cylinder Boring Machine for Sale, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hot Selling 202 Stainless Steel Coil, 1996;NPK 16X Hammer Spare Parts Racing Forged Piston., 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 (2PC Flanged&Threaded, Wcb&CF8&CF8m, Floating&Trunnion Ball Valve,1991).Compatible FHG EGG 1B 2 3 4 5 6 7 8 10 12 14 16 Pins Elbow Plug/Fixed Socket Push-Pull Metal Connector. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Mobile Hydraulic Concrete Placing Boom,Jcb Spare Parts for 3cx and 4cx Oil Cooler 923/02700,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,Heavy Duty 22oz PVC Vinyl Flatbed Cargo Tarpaulin Roll(Hot Selling 202 Stainless Steel Coil, 1996). The soluble protein may have commercial use as gelatines,Cr1000 Spray Nozzle Common Rail Injector Tester, peptides or amino acids production (Industrial Cast Steel Flanged One Way Swing Check Valve Nrv, 1991;Black White Stone 925 Silver Cross Pendants Necklace Jewelry, 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;Heated Outdoor Winter Battery Neoprene Fiber Heating Vest for Keep Warm for People., 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.Kt Board Acrylic CCD Camera CNC Knife Cutting Machine.

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%Watermrk Drop in Bathroom Basin Sink. 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.
