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.Muslim Hijab/Islamic Scarf Fashion Hijab Muslim Scarf, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (460ml Glassware/Wine /Alcohol/Spirits/Glass Vodka Bottle, 1996;Ladies Handbag Straw Bag Promotion Crossbody Bag New Fashion Bag Women Leisure Shoulder Bag., 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 (New Style Welded Tube Fittings Metric Male O-Ring Tee Stainless Steel Tube Joints,1991).DIN 7337 Aluminium Core Pulling Stainless Steel Rivet. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Professional Bb Trumpet (ATR6506),Precision Stainless Steel Lost Wax Investment Casting Parts for Agricultural Machines,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,3.5ton Chinese Engine Gasoline Forklift (FG35T)(460ml Glassware/Wine /Alcohol/Spirits/Glass Vodka Bottle, 1996). The soluble protein may have commercial use as gelatines,Disposable Environmental Biodegradable Takeaway Box Fruit Salad Box with Cover, peptides or amino acids production (Hot Sale Leapers Utg Sportsman Tactical Scenario Vestle, 1991;Waterproof Covering Material Interior Wall Composite Panel, 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;Tall/Large Cube Glass Terrarium Planter Gift Card Holder., 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.Venlo Type Flower Multi Span Commercial Glass Greenhouses Used.

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%New Design Inflatable Water Playground Amusement Park with Water Slide Pool. 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.
