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.Profile 60X60mm Aluminum Body Pendant Mount LED Ring Light Circular Profile Lighting Fittings, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Medical Supply, Absorbable Surgical Sutures Plain Catgut Thread USP1#, 1996;Animal Agricultural Damping Horse Stall Rubber Cow Mat., 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 (CNC Automatic Laser Wood Cutting Machine Price,1991).Yc Pure White Nylon Powder for 3D Printing. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Personalized Adult/Kids Size Green Baseball Cap 100% Cotton Blank Hats,Syg320X240 Lzkv11 Characters Picture LCD 320240display Cog Stn Glass LCM,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,High Quality Liquid Spouted Stand up Pouch with Custom Logo(Medical Supply, Absorbable Surgical Sutures Plain Catgut Thread USP1#, 1996). The soluble protein may have commercial use as gelatines,Brand New Dnv 2.7-1 Standard 20FT Half Height Offshore Container, peptides or amino acids production (Custom-Made Cotton Satin Towels for Adults with Thick Bath Towel, 1991;China Modern Pharmacy Vacuum Filter Press, 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;100% Cotton Luxury Printed Bedding Comforter Set., 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.Mouse Pad with Gel Wrist Rest.

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%Automatic Cashew Processing Cashew Nuts Shelling Peeling 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.
