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.Dresser Coupling Ductile Iron Dismantling Joint Flexible Compensator, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (PP Woven Rice, Beans, Maize, Wheat Bag Chemical Fertilizer Bag, 1996;Aluminum Hot Forging Accessories Machining Parts., 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 (Building Wall Machine for Hot Machine,1991).New Arrival Amazon Hot Style Printed Slip Dress for Women Summer. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Metal Cuting CNC Plasma Cutting Machine (DW1325),Scc750A High Speed Metal Processing Oil Metal Cutting Lubricant,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,Expanded Metal Infill Panel Metal Mesh Custom Made(PP Woven Rice, Beans, Maize, Wheat Bag Chemical Fertilizer Bag, 1996). The soluble protein may have commercial use as gelatines,DC Motor for Massagers, peptides or amino acids production (High Speed Heavy Duty Customized Radio Shuttle Pallet Racking for Warehouse Storage, 1991;Widely Used Cheap CNC Plasma Flame Cutting Machine for Sheet Metal Industry, 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;Custom Good Quality Outdoor Music Wireless Cooler Speaker Box., 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.OEM Viton Mechanical Rubber Oil Seal.
