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.20kv 50kVA High Voltage Dry Type Power Supply Transformer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Manufacturer Custom Injection Molded Plastic Shell of Automobile Headlamp, 1996;High Quality OS2 12 Core Singlemode High Density Data Center MPO-LC Breakout 2mm Low Insertion Loss 5m LSZH Fiber Optic Patch Cable Per Meter., 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 (4 Styles Blue Glass Crystal Butt Beads Spiral Plug,1991).Electronic Automatic DC Motor Valve Industrial SUS Welded Ball Valve. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Industrial Activated Carbon Water Filter Industry Water Treatment,2016 New Generation Sausage Making Machine,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,Magnetic Mixer Mixing Tank with Bottom Agitator (MTK)(Manufacturer Custom Injection Molded Plastic Shell of Automobile Headlamp, 1996). The soluble protein may have commercial use as gelatines,Wholesale Aluminum Frame Outdoor Advertising Pop up 3X3 Custom Portable Folding Gazebo Tent, peptides or amino acids production (New Christmas Alloy Colorful Animal Owl Tassel Earrings Cute Fashion Full of Diamond Studs (03), 1991;China Supplier Building Construction Steel Frame (ZY431), 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;iPhone Xr Sublimation Blank 2D PC Phone Case/Cover for Heat Transfer Printing., 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.Lab Equipment portable Fume Hood.
