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.2.5X/3.5X Glasses Clip Dental Loupes Binocular Surgical Loupe Lab Medical Magnifier, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Outdoor UV Resistant Decoration Material WPC Exterior Wall Panels, 1996;Multi-Tool Vibrating Knife Cutting Machine for Leather, Fabric, Textile., 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 (Customized Factory Price Stone Carving Decoration Aristotle Bust Marble Statue Mfsb-04,1991).Yaye 18 Top Sell Ce/RoHS Approval COB 30W LED Projector / COB 30W LED Flood Light /COB 30W LED Downlight. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,355nm UV Laser Marking Equipment for Crystal Materials,Mobile Network Automatic Tracking Selfie Camera Multilayer HDI PCB,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,Wire Mesh Welding Size 10mm X 10mm(Outdoor UV Resistant Decoration Material WPC Exterior Wall Panels, 1996). The soluble protein may have commercial use as gelatines,P4.75 Indoor Single Dual Color Advertising LED Display Billboard, peptides or amino acids production (New Smart Housing Price Motion Sensor All in One Integrated Solar LED Street Light IP65, 1991;Plug-in Assembly Type Straight Through Joint and Insulation Joint, 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;Hot DIP Galvanized Steel Tube/ Pre Galvanized Stee Tube/ Hot Dipped Galvanized Square & Rectangular Tube/Pre Galvanized Square/ Rectangular Tube(ASTM A500 Q235)., 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.High Quality Muscle Growth Bodybuilding Peptides Powder Hexarelin.
