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.Ocrown Holographic Dark Blue Glitter Flakes Decoration Supplier, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Custom Army Style 100% Polyester Fiber Mens Polo Shirt, 1996;E2000/APC Connector Type Plug-in Female to Male Fixed Fiber Optic Attenuator., 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 (Twisted Annealed Wire for Binding,1991).Wholesale Pyrex Heating Water Bottle Cold with Stainless Steel Lid. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Wholesale Fashion Jewellery Lady Eardrop Earrings for Women,High Quality Cheap Small Metal Hard Guide Way Flat Bed Horizontal CNC Lathe Machine Ck0640,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,Yuhuan Manufacturer Hydraulic Fittings Quick Connection Pipe Fittings Hose Fittings(Custom Army Style 100% Polyester Fiber Mens Polo Shirt, 1996). The soluble protein may have commercial use as gelatines,Full Automatic AAC Concrete Lightweight Block Making Machine, peptides or amino acids production (Stainless Steel CF8/CF8m Street Elbow Pipe Fittings, 1991;Pure Epitalon Peptide 50mg Powder Epitalon for Bodybuilding, 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;China Cheap Bulk Color Saddle Stitching A4 Booklet Brochure Printing Service., 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 Manganese Steel Gp100s Gp200 Gp300 Concave Cone Crusher Parts.

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%Two - Way Double Row Thrust Tapered Roller Bearings. 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.
