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.Home Furniture Set Restaurant King Throne Wedding Banquet Dining Chair, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (What′s Kind of Machine for Making Organic Fertilizer Granules, 1996;Gsjl 91/1 Multibar Computerized Jacquard Warp Knitting 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 (Home and Hospital Electric Patient Lift,1991).Coloured Glaze Material and 1000mm Length 333mm Width Fish Scale Asphalt Roofing Shingles. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,M4 Pneumatic Air Driven Liquid Booster Pump Various Good Quality,Motorcycle Intake Manifold Carburetor Interface Connector Joint Motorcycle Parts,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,DC 12V Power Relay for Smart House(What′s Kind of Machine for Making Organic Fertilizer Granules, 1996). The soluble protein may have commercial use as gelatines,2019 Good Price Stainless Steel Wedge Wire separation Screen Sieve Bend Screen Filter for Water /Wastewater Treatment, peptides or amino acids production (Medical Human Body Thermometer, 1991;Patent Product Solar Insect Killer Lamp, Made in Goldsun, 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;Greenhouse Fixing Film Profile Lock Channel and Spring Wire., 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.30W Fiber Laser Marking Machine Deaktop Laser Printer for Plastic Bottle /Aluminium Product/Metallic Products.

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%Wholesale Custom Mens Heated Down Jacket. 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.
