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.Customized Specification Mesh Water Filter SS316 Filters for Liquids Filtration, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (PA Flexible Plastic Corrugated Loom Tubing, 1996;Stainless Steel Rectangular Kitchen Washing /Wash Sink with Double Bowl., 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 (Belt Conveyor in Heavy Duty Industry for Mining, Coal, Power,1991).Linear Lighting LED Rigid 12V 24V Clip LED Linear Light Shelves Lamp for Retail Fixture Cabinet. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,3-Way T Type Elbow Quick Connect Pneumatic Fitting,China Superior Quality Soya Protein Food Production Machine Line,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,Ocrown Holographic Dark Blue Glitter Flakes Decoration Supplier(PA Flexible Plastic Corrugated Loom Tubing, 1996). The soluble protein may have commercial use as gelatines,Custom Army Style 100% Polyester Fiber Mens Polo Shirt, peptides or amino acids production (E2000/APC Connector Type Plug-in Female to Male Fixed Fiber Optic Attenuator, 1991;Twisted Annealed Wire for Binding, 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;Wholesale Pyrex Heating Water Bottle Cold with Stainless Steel Lid., 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.Wholesale Fashion Jewellery Lady Eardrop Earrings for Women.
