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.Puer/off White Melamine Particle Board/MDF Board, White Board, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Pet Juice Bottle Cap and Preform Making Automatic Injection Moulding Machine, 1996;2000LTR Horizontal Foam Tank Fire Fighting Suppression., 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 (High Spped Weaving Machine 6,1991).Era Valves, PVC Butterfly Valve Gear Type, NSF-Pw & Upc. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Small Poultry Pig Feed Farm Steel Silo for Sale,Animal/Poultry/Cattle/Cow Silage Grass Feed Cutter Machine,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,P3.0 576*576mm Display Panel LED for Hotel Church Stage Lighting(Pet Juice Bottle Cap and Preform Making Automatic Injection Moulding Machine, 1996). The soluble protein may have commercial use as gelatines,Made in China 12 Inch Aluminum Flexible Duct Pipe, peptides or amino acids production (18K White Gold Octagon Emerald Cut Moissanite Diamond Jewelry Engagement Ring, 1991;Industrial High Pressure Food Quality Rubber Hydualic Hose for Water Food, 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;Safe Delivery Effective Sarms Mk 677 for Bodybuilding., 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.12# X 14# Electric Galvanized Double Strands Barbed Wire.

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%Gaint Inflatable Animal Slide. 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.
