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.DIN7504 Stainless Steel Pan Head Philips Self Drilling Screw, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Auto Two Piece Folder Gluer for Corrugated Box, 1996;British Standard 2 Gang 1 Way Wall Light Switch., 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 (Vibratory Finishing Polishing Machine for Aluminum Brass Metal Steel Parts,1991).Commercial Fitness Gym Strength Equipment Half Rack Body Solid Power Cage. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Amber Green Blue Transparent Spray Perfume Bottle Glass Bottle for Perfume,Natural Cannabidiol Cbd Isolate Powder Cbd Powder Cbd Oil CAS 13956-29-1 China Supplier,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,Two Head Mattress Machines Pocket Spring Coiling Machine Sewing Machine(Auto Two Piece Folder Gluer for Corrugated Box, 1996). The soluble protein may have commercial use as gelatines,P-Level Sp-Level Mute Interchangeable Linear Motion Guide Rails, peptides or amino acids production (Heavy Zinc Galvanized and PVC Coated Binding Cut Iron Wire Stainless Steel Wire, 1991;Rectangular Stainless Steel Pipe SS304, 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;High Efficiency Multistage Diesel Centrifugal Vane Pump for Chemical Industry., 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.6.6kw LiFePO4 Charger for Lithium Battery Pack.
