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.Movable Partition Walls for Room Division, Hotel and Shopping Mall, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Carboxy Terminal Collagen Crosslinks Elisa Kits, 1996;Various Colors Nylon and Stainless Steel Kitchen Tools., 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 (355nm UV Laser Marking Equipment for Crystal Materials,1991).Metal Separating Gold Brass Zippers for Sale. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Quartz Window, Polished Quartz Disc, Quartz Plate Optical Fused Clear Quartz Plate,OEM Refrigeration Digital Thermometer,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,BA Finished Seamless Stainless Steel Tube (304, 304L, 316, 316L)(Carboxy Terminal Collagen Crosslinks Elisa Kits, 1996). The soluble protein may have commercial use as gelatines,Wood Debarker, Tree Shaving Machine, Tree Peeling Machine for Paper Making, peptides or amino acids production (79/1000fhv Fuel Filter Electric Fuel Pump Oil Water Separators for Yanmar, 1991;Two Roll Rubber & Plastic Mixing Mills Tire 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;5PCS Travel Mini Eye Makeup Brushes Set Eyebrow Brush Make up Brushes., 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.Hot Sale 25kw Grid Tied Home Solar Panel System Kit.
