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.14dBi 470-790MHz Outdoor Digital UHF VHF TV Antenna, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Strong Cleaning Bow-Tie Scourer Pad Shape Abrasive Green Scouring Pad, 1996;Petrol Chain Saw Wood Cutting Machine 38cc Chainsaw CS3800., 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 (Heavy Duty Rope12 Strand PP PE Mixed Pull Mooring Mope,1991).High Cut Genuine Leather Safety Shoes for Electrician in Guangzhou. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Quality 4X2 and 6X4 China Heavy Duty Tractor Truck HOWO Tractor Truck,Aluminum Bright Polished Mirror Sheet,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,Chik Chrome Steel High Carbon Ball Bearing for Motor Bike Automobile (6215 RS ZZ open)(Strong Cleaning Bow-Tie Scourer Pad Shape Abrasive Green Scouring Pad, 1996). The soluble protein may have commercial use as gelatines,Professional Motorcycle Reflector Injection Plastic Parts Mould Maker, peptides or amino acids production (O Shape Hole Design Small Round Hole Fixed Head LED Downlight 9W 11W, 1991;Cheaper Factory Price! Foam Slicing Vertical Cutting Machine in China, 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;Auto Engine Radiator for Honda Accord 97-00 CF4 OEM 19010-PDA-E51., 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.Customized Souvenirs Tin Metal Number & Name Plate for Car.

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%Heat Pump Food Cabinet Dog Food Pet Food Dryer 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.
