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.0.15mm 0.2mm 0.3mm 0.5mm 1mm 2mm 5mm 2014 Aluminum Alloy Coil for Food Preparation, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (China Factory Top Push Slide Switch with 7pin SMD Type (MSK-1106), 1996;Double Bowl Undermount for Stainless Steel Kitchen Sink., 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 (Fitness Athletics Shorts Men Workout Clothing Sweat Gym Shorts Custom Mens Sport,1991).Bitumen Waterproof Membrane Minerla Surface Waterproof Material. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,M10 3D Solid Non-Woven Folded Mask Body Making Machine,Pfc Inductors with Adjustable Dimension and Wire Diameter,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,Automatic Permanent Magnetic Lifter(China Factory Top Push Slide Switch with 7pin SMD Type (MSK-1106), 1996). The soluble protein may have commercial use as gelatines,Large Diameter Aluminum Pipe 3004, peptides or amino acids production (Hpzmflb Energy Saving High Lumen IP65 Outdoo LED Flood Light, 1991;Ambient Light Rejection Wall Hanging Projector Screen 100 for Home Theater, 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;Copy Paper Writing Paper Newspaper Toilet Paper Tissue Paper Kraft Paper Fluting Paper A4 Paper Facial Paper White Board Paper Wrapping Paper 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.Wholesale Logo Printing Cheap Gold Custom Paper Clip.
