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.Fashion European 925 Sterling Silver Butterfly Flower Crystal Engagement Ring, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Reflective Hard Reflector, Relfective Plastic Reflector, Hard Keychain Reflector, 1996;Heat Pump Non-Programmable HVAC Room Thermostat., 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 (Beer Festival Transparent Advertising Glass Beer Cups Beer Mugs Cold Water Glass Tea Juice Bottle Thicken Printed Logo,1991).Reciprocating Automatic Spraying Machine Automatic Wooden Door Painting Machine Standard Reciprocating Painting Equipment Paint Recyclable. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Professional Handheld Underground Gold Metal Detector Waterproof Pinpointer,Pipe Production Line/ Pipe Used Adjustale or Self Adjustable Pipe Welding Turning Roll/ Rotator,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,Injector Pump Calibration Test Bench(Reflective Hard Reflector, Relfective Plastic Reflector, Hard Keychain Reflector, 1996). The soluble protein may have commercial use as gelatines,ASME/ASTM Butt-Welding Stainless Steel Plate Flange, peptides or amino acids production (500L Unitank Fermenter (EV 500L, TV650L) /Beer Brewing Sanitary Fermentation Fermenting Tank Beverage Storage Tank, 1991;Stainless Steel Straight Pneumatic Fitting Quick Connect Air Fittings, 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;Polyester / Polypropylene Woven Geotextile for Road Construction., 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.Granite Stone Jaw Crusher of Mining Machine.
