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.Stainless Steel Cheese Making Machine Electric, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cpri Outdoor Patch Cord Fullx LC Duplex for Huawei & Ericsson Bts, 1996;100W Dimmable LED Corn Bulb with Meanwell Driver., 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 (Pet and Animal Food Extrusion Machine,1991).Factory Various Spi /I2c /0.5-4.5V /4~20mA Air Water Gas Pressure Sensor Transducer. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Hexagonal Wire Mesh Chicken Wire Mesh High Quality,V-32 New Special UPS Solar Battery Cabinet Box Case,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,4-14 Manual Staple Gun with Staples for Hand Tools(Cpri Outdoor Patch Cord Fullx LC Duplex for Huawei & Ericsson Bts, 1996). The soluble protein may have commercial use as gelatines,Handmade Individual Fast Fanning 3D Private Label Lashes Wholesale Premium Easy Fan, peptides or amino acids production (Fashion Jewelry Lab Gemstone 925 Sterling Silver Pendant Necklace with Garnet/Citrine, 1991;Sm5r30602b Auto Car Ls1 Komatsu Kobelco Engine Suzuki GM Automobile Wiring Harness, 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;Biomass Drum Wood Chipper with Competitive Price., 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.High - Tech RFID in Airports Automated Check in and UHF RFID Bag Tags.

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%Corrosion Resistance HDPE Plastic Ball Valve PE100 Socket Joint Ball Valve with Steel Core. 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.
