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.Diamond Segments 2000mm Diameter Granite Cutting Blade, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Produce N2o for Medical Gas Equipments, 1996;Hot Selling Furring Channel Fittings Suspended Ceiling Accessories., 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 (90m3 Per Hour Mobile Concrete Pump,1991).China High Quality CATV FTTH 1550 Nm External Modulated Optical Transmitter. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,FTTB Wdm Optical Receiver with 2 Output / AGC FTTB Optical Node,All Weather Rattan Handwoven Swing Outdoor Home,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,Pond Self Priming Booster suction  Water Pump with Pressure Switch(Produce N2o for Medical Gas Equipments, 1996). The soluble protein may have commercial use as gelatines,Digtal Camera for Sewer Line Inspection System with Self Level and Meter Counter, peptides or amino acids production (Modern Furniture Brick Finishing Wood Fireplace Mantel Surround Electric Fireplace, 1991;for Wall Decoration Glass Silver Metal Aluminium Mosaic Tile, 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;100% Polyester Gabardine Shirting Fabric with Transfer PrintingTree., 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.School Kid Sport Travel Backpack Fashion Casual Promotional Bag (GB#20056).
