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

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%Digital Lock Electronic Door Lock Password Keypad Number for Cabinet Door. 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.

CONCLUSIONS

Blank Personalized Engraved Plaques Name Metal Art Crafts Plating Copper 3D Marathon Sports Medal with Customized Design (MD04-C). Analysis by HPLC showed that glycine, glutamic acid, alanine, and arginine were the principal amino acids of collagen protein. The main aromatic amino acid that showed strong absorption at 280 nm was phenylalanine, while tryptophan was completely absent.
