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.Clutch Brake Booster for Yutong Zk6127h Bus, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (20399560 Oil Seal 125X148X9.7 for Volvo, 1996;Horizontal Milling and Boring CNC Lathe Machine., 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 (Kids Playground Rubber Floor Mat,1991).100t 3200 mm Simple Operation Hydraulic Bending Machine Used in Luminum Alloy Doors and Windows Industry. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,36V 350W 12inch Electric Bike Power Wheelbarrow Front Geared Motor Wheel,Sinotruk 12 Wheels 35, 000 Litres LPG Tanker Truck,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,All in One Make up Brushes Kit 10PCS Professional Travel Makeup Brush(20399560 Oil Seal 125X148X9.7 for Volvo, 1996). The soluble protein may have commercial use as gelatines,Nickel Plating Cloisonne Gold Enamel Metal Medal (068), peptides or amino acids production (SLS 3D Printing ABS Nylon Prototyping Service Machining 3D, 1991;China Supplier Laboratory Mixer for Comstic, 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;Water and Oil Repellent Singeing Cement Plant Use Nomex Dust Collector Filter Bag., 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.Fiber Optic Equipment Sc/APC Quick Connector Sc Fast Connector Field Assembly Connector.

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%Black Watermelon Seeds with Good Quality and Best Price. 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.
