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.Industrial Sausage Meat Smoker Oven/Smokerhouse Oven, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Men′s High Quality Mercerised Cotton Business Dress Socks, 1996;Livining Room Rugs Geometric Patterns Carpets 6′*9′., 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 (Lamella Clarifier for Wastewater Treatment Plant,1991).Tube Cutting Machine CNC Fiber Laser Metal Pipe Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Mobile Phone LCD Screen for iPhone 6s LCD Screen Touch Screen,Semiauto Rigid Box Production Line with Automatic Vision Gluing Machine (ZS-6418S),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,2018 2 Ply Sherpa Fleece Blanket Throw for Australia Market(Men′s High Quality Mercerised Cotton Business Dress Socks, 1996). The soluble protein may have commercial use as gelatines,Concentric Reducer 3 Inch*2 Inch A105 ASME B16.9, peptides or amino acids production (E6000 Handheld Three Phase Power Quality and Energy Analyzer, 1991;Qg Jg Fg Series Air Dryer Equipment Factory, 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;Motor Bearing 6014 2RS Deep Groove Ball Bearing., 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.PP Extended Stretched Wc Toilet Drain Pipe with Steel Wire Reinforced Tube Hose Extrusion Line.
