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.Aluminum Road Stud, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Lab Water Instruments/Lab Water Purification System Micro, 1996;Qi Wireless Charger Portable Charger10W Fast Charging for iPhone/Sumsung /LG/Lenovo/Mi/Nokia., 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 (Adult Neoprene Sport Summer Beach Aqua Swimming Shoes,1991).Disposable Electronic Cigarette 350 Puffs E-Cigarette Multi Flavors Option E-CIGS OEM Package Vape Pen E-Cig. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Lightweight Compact 70d Ripstop Nylon Parachute Hammock,0.15mm 0.2mm 0.3mm 0.5mm 1mm 2mm 5mm 2014 Aluminum Alloy Coil for Food Preparation,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,China Factory Top Push Slide Switch with 7pin SMD Type (MSK-1106)(Lab Water Instruments/Lab Water Purification System Micro, 1996). The soluble protein may have commercial use as gelatines,Double Bowl Undermount for Stainless Steel Kitchen Sink, peptides or amino acids production (Fitness Athletics Shorts Men Workout Clothing Sweat Gym Shorts Custom Mens Sport, 1991;Bitumen Waterproof Membrane Minerla Surface Waterproof Material, 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;M10 3D Solid Non-Woven Folded Mask Body Making Machine., 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.Pfc Inductors with Adjustable Dimension and Wire Diameter.
