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.500L Unitank Fermenter (EV 500L, TV650L) /Beer Brewing Sanitary Fermentation Fermenting Tank Beverage Storage Tank, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Stainless Steel Straight Pneumatic Fitting Quick Connect Air Fittings, 1996;Polyester / Polypropylene Woven Geotextile for Road Construction., 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 (Granite Stone Jaw Crusher of Mining Machine,1991).Ductile Iron Pipe Accessories/Fittings/Joints/Coupling/Adaptor. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Galvanized Animals Wire Mesh Fence Grassland Fence Professional Manufacturer,The Newest Cut One Arcade Coin Operated Prize Cutting Scissors Game Machine,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,Orange Color Long Style Cotton Drawstring Bag, Gym Sport Backpack, Gift Bag(Stainless Steel Straight Pneumatic Fitting Quick Connect Air Fittings, 1996). The soluble protein may have commercial use as gelatines,Wholesale All Kinds Cheap Plush Animal Baby Slippers, peptides or amino acids production (Lithium Battery Long Times Cycle 12V Solar Battery Light Weight 12V 100ah LiFePO4 Battery for Car, 1991;Movable Folding Knuckle Boom Hydraulic Truck-Mounted Crane, 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;Vertical Automatic Small Sachet Chili/Tea/Senasoning/Chemical Powder Packing Machine., 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.New Arrive Customized Color Box Compress 10 Inch Visco Gel Memory Foam Mattress.

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%AAC Block Production Line / AAC Equipment Manufacturing/ Machinery. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
