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.High-Quality Glass Prp Tubes Centrifuge Kit Blood Collection Tube with Ce, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Tire Rubber Powder Recycling Equipment for Sale Truck Tires Rubber Shredding Facility, 1996;Cheap Customized Aluminium Sand Casting., 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 (Plastic Stand up Coffee Food Packaging Bag with Resealable Zipper,1991).Non-Woven Greenhouse Insulation Felt Making Machine Production Line/ Sell Greenhouse Insulation Quilt Production Line. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Washing Machine Components Stainless Countersunk External Tooth Lock Washers From China,New Arrival Wafer Type Pneumatic Fluorine Lined Butterfly Valve,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,High Quality RV Electric Seating Recliner(Tire Rubber Powder Recycling Equipment for Sale Truck Tires Rubber Shredding Facility, 1996). The soluble protein may have commercial use as gelatines,2mm Mirror Glass/Coated Glass for LED, LCD, Computer Screen etc, peptides or amino acids production (100% Hand-Painted Canvas Oil Painting Wall Art for Trees, 1991;Factort Price Cattle Beef Slaughtering Equipment for Sale, 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;Supreme 524 Mv Sea Kayak., 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.API 594 Super Duplex Steel Single Disc Dual Disc Plate Wafer Check Valve.

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%Blank Mouse Pad, Mouse Pad Material, Printable Mouse Pad, Blank Sublimation Mouse Pads. 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.
