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.Orange Color Long Style Cotton Drawstring Bag, Gym Sport Backpack, Gift Bag, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wholesale All Kinds Cheap Plush Animal Baby Slippers, 1996;Lithium Battery Long Times Cycle 12V Solar Battery Light Weight 12V 100ah LiFePO4 Battery for Car., 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 (Movable Folding Knuckle Boom Hydraulic Truck-Mounted Crane,1991).Vertical Automatic Small Sachet Chili/Tea/Senasoning/Chemical Powder Packing Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,New Arrive Customized Color Box Compress 10 Inch Visco Gel Memory Foam Mattress,Modern Stainless Steel 3 Person Small Home Elevator with Vvvf System for Sale,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,Taiding Custom Tank Sheet Metal Fabrication(Wholesale All Kinds Cheap Plush Animal Baby Slippers, 1996). The soluble protein may have commercial use as gelatines,Airtight Candy Bin with Scoop, peptides or amino acids production (Wholesale Factory Price Emark R112 22 120W RC 6X6 Truck Offroad Red LED Light Bar, 1991;Peugeot Silicone Rubber Car Remote Key Case Cover for Peugeot Key Shell, 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;3 Layer Round Tea Tin with Air Tight Lid., 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.China PA System Power Amplifier with Enough Rated Power.

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%Angle Iron Steel Purlin Q235/345 Equal Angle Steel / Hot Dipped Galvanized Beam. 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.
