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.Best Seller Hot Sale Compatible Lemos Feg 2b 26 Pin Metal Circular Push Pull Self Latching Connector, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (FRP GRP Fiber Reinforced Plastic Fiberglass Gratings, 1996;Customized Length Medical Suction Connecting Tube with Yankauer Handle Crowed/Standard Tip., 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 (Fashion Mens Long Zipper Credit Card Purse PU Phone Wallet with Strap,1991).48V DC Powered Air Conditioner for Outdoor Cabinet 2000W. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,New Funfair Outdoor Sky Space Walk Tourist Bike Amusement Park Rides,Sleeved Wire Harness for Industry Equipment,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,Hot Filling 4-in-1 Fruit Juice with Pulp Making Bottling Machine(FRP GRP Fiber Reinforced Plastic Fiberglass Gratings, 1996). The soluble protein may have commercial use as gelatines,Home Use Standing Modern Floor Lamp (KAF6108), peptides or amino acids production (Y2ej Cast Iron Electromagnetic Brake Asynchronous AC Electric Induction Motor, 1991;1.75mm 3mm ABS PLA PC 3D Printer Filament Machine, 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;Korea Technology Commercial Waterproof Eco Click Lock Luxury Vinyl PVC Plank Flooring., 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.Nutrition Enhancer Environmental Nutritional Yeast Powder.

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%5W Ultra-Thin Tiltable LED Down Light. 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.
