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.Transparent 43/410 Soap Dispenser Hand Wash Pump Foam Pump, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Viscose and Polyester Blends Spunlace Nonwoven Fabric For Home Wipes, 1996;99% Purity Serms Steroids Megestrol Acetate CAS 595-33-5., 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 (ATV Spiked Chain Harrow for Farming,1991).Galvanized PVC Concertina Razor Barbed Wire Barrier Fence Wire Cbt-60. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Custom Logo Waterproof Travel Adult Men Shoulder Sling Bag Crossbody,Fashionable Natural Bamboo Wood Sunglasses for Men,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,Solar Powered Outdoor Lighting LED Solar Wall Light(Viscose and Polyester Blends Spunlace Nonwoven Fabric For Home Wipes, 1996). The soluble protein may have commercial use as gelatines,Outdoor New Design Monitor Cabinet Taxi Advertising LED Signs, peptides or amino acids production (9~12 Inch Mechanical Backing Plate, 1991;OEM Thermal Break Aluminum Profile for Aluminum Windows, 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;Aluminum Window System Thermal Break Strip (HK Stype35.3mm)., 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.LED Bulb Light UFO Light Recruitment Distributor.

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%High Quality Melamine Paper Manufacturer for Decoration. 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.
