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.14443A Code Chip for Optical Disc Management and Positioning of Hf RFID Tags, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Ss400 Corner Metal Sheet Bar Galvanized Angle Iron, 1996;High Speed Automatic Multi Rolls Toilet Paper and Kitchen Towel Packing Machine., 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 (Stainless Steel Coils in Top Quality with Reasonable Price From Foshan Manufacturer,1991).Chinese Jbcz Handy Operation Threading Machine and Coupler. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Promotional Reusable Foldable PP Non Woven Shopping Bag,Customized Made EVA Swim Kickboard Swimming Kickboard Swim Kick Board Swim Kickboard Swim Board,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,Factory Price Printing Doy Pack Bag(Ss400 Corner Metal Sheet Bar Galvanized Angle Iron, 1996). The soluble protein may have commercial use as gelatines,Teaching Equipment Laminar Flow Visualization Unit Fluid Mechanics Lab Equipment Vocational Training Equipment, peptides or amino acids production (New Design 4*2 Street Cleaning Machine Sweeping Truck with Brushes, 1991;Direct Factory Tebuconazole Price Fao Bactericide Tebuconazole Price, 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 Quality Plastic Pipe Adapter HDPE100 Pipe Fitting Flange Adapter PE Butt Fusion Pipe Flange Adapter for Water Supply SDR17., 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.Engine Parts Rubber High Quality Timing Belt 111ru25.
