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.D8tc High Performance 3-Electrode Motorcycle Spark Plug, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Blank Mouse Pad, Mouse Pad Material, Printable Mouse Pad, Blank Sublimation Mouse Pads, 1996;Custom Makeup 10 Color Private Label Eyeshadow Case Palette Packaging., 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 (Waterproof Microfiber Double Layer Insulated Thermal Pizza Bag Picnic Bag,1991).19m Mobile LED Display Billboard for Advertising Screens. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Nice Appearance Brass Metal Sheet Stamping,Hot Sale Starter Motor Testing Equipment for Truck, Bus,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,Home Machine 2019 New Commercial Treadmill Gym Equipment(Blank Mouse Pad, Mouse Pad Material, Printable Mouse Pad, Blank Sublimation Mouse Pads, 1996). The soluble protein may have commercial use as gelatines,New 50ml Glass Spray Bottle Green Refillable Bottles Vial with Glass Dropper for Essential Oil Perfume Cosmetic, peptides or amino acids production (Waste Paper Recycling Egg Tray Machine Egg Carton Molding Machine Fruit Tray Egg Tray Forming Line, 1991;Clothing Hard Tag Security Tag for Supermarket/Retail Store, 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;150 Ton Hydraulic Press Machine for Cooking Pot Making., 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.Mirror Face Style Acrylic Round Wall Mounted Hanging Fish Bowl.

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%White Crystal Fashion Bridal Jewelry Accessories Wedding Tiara. 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.
