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.


Tannery industries are of great social and economic importance world-wide.Heat Pump Non-Programmable HVAC Room Thermostat, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Beer Festival Transparent Advertising Glass Beer Cups Beer Mugs Cold Water Glass Tea Juice Bottle Thicken Printed Logo, 1996;Reciprocating Automatic Spraying Machine Automatic Wooden Door Painting Machine Standard Reciprocating Painting Equipment Paint Recyclable., 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 (Professional Handheld Underground Gold Metal Detector Waterproof Pinpointer,1991).Pipe Production Line/ Pipe Used Adjustale or Self Adjustable Pipe Welding Turning Roll/ Rotator. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Injector Pump Calibration Test Bench,ASME/ASTM Butt-Welding Stainless Steel Plate Flange,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,500L Unitank Fermenter (EV 500L, TV650L) /Beer Brewing Sanitary Fermentation Fermenting Tank Beverage Storage Tank(Beer Festival Transparent Advertising Glass Beer Cups Beer Mugs Cold Water Glass Tea Juice Bottle Thicken Printed Logo, 1996). The soluble protein may have commercial use as gelatines,Stainless Steel Straight Pneumatic Fitting Quick Connect Air Fittings, peptides or amino acids production (Polyester / Polypropylene Woven Geotextile for Road Construction, 1991;Granite Stone Jaw Crusher of Mining Machine, 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;Ductile Iron Pipe Accessories/Fittings/Joints/Coupling/Adaptor., 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.Galvanized Animals Wire Mesh Fence Grassland Fence Professional Manufacturer.
