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.Automatic Professional LED Display Ceramic Hair Curling Iron, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (CNC Machining High Precision A380 Die-Casting Aluminum Auto Spare Parts, 1996;China Gooseneck Lowboy/Low Bed/Lowbed Utility Heavy Truck Tractor Semi Trailer., 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 (Vulcanizing Machine /Rubber Tiles Vulcanzing Press,1991).Belt Driven Air Compressor Parts Atlas Copco Double Hanbell Compressors Industrial Air Cooled Screw Water Chiller Low Pressure Oilless Air Compressors Low. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Protein Shaker Bottle with 2 Compartments, Leak Proof, Shaker Cup, 17-Ounce,Omni Newest Manager Desk Office Smart Office Table Office Staff Table,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,6oz/175ml Plastic Packaging Pharmaceutical Plastic Medicine Container with Plastic Screw Cap(CNC Machining High Precision A380 Die-Casting Aluminum Auto Spare Parts, 1996). The soluble protein may have commercial use as gelatines,30W Electric Insect Trap Mosquito Bugs Vinegar Flies Flying Insect Killer Lamp Mosquito Insects Repellent Traps, peptides or amino acids production (Plastic Microwave Lunch Container/ Lunch Box Plastic/ PP Food Storage, 1991;Full-Auto CNC Cutting Machine for Architecture Glass Sheet, 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;Oring O-Ring All Kinds of Rubber Material NBR Nr EPDM Rubber Product., 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 Forming Pushing Elbow Making Machine.
