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.Crusher for Animal Waste/ Chicken Manure, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Fast Construction Easy Installation Large Wide Span Prefabricated Steel Structure Industrial Construction Metal Building Warehouse Shed in Customer Designs, 1996;Threaded Locking Circular Connectors M16 680., 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 (Dsola Best Selling High Current Carrying Capacity Mc4 Solar Branch Connector,1991).Wholesale Price Printable Proximity Em 125kHz Tk4100 Chip RFID Smart ID Card. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Disposable Sterile Safety Blood Lancet,Plush Comfort Spring Mattress Cheap Price for Wholesale,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,3 In1 Digital Vacuum Therapy Cavitation RF Slimming Machine for Weight Loss(Fast Construction Easy Installation Large Wide Span Prefabricated Steel Structure Industrial Construction Metal Building Warehouse Shed in Customer Designs, 1996). The soluble protein may have commercial use as gelatines,Railway Interior Seating Car for Coach/Lrt/Metro/Emu/Subway, peptides or amino acids production (Titanium Stainless Steel Rings Rose Gold Anti-Allergy Smooth Simple Wedding Couples Rings, 1991;1X8 Insert Type Fiber Optic PLC Splitter Sc/APC Connector, 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;Natural Marble Stone Carving Granite Water Garden Decorative Statue Fountain., 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.Waterproof LED Flash Shoe Light Crystal Epoxy Resin.

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%Tube Cutting Machine CNC Fiber Laser Metal Pipe 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.
