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.Digger Arm Small Wheel Loader (HQ908) with CE, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (15ml 18ml Glass Fish Model Perfume Bottle with Plastic Sprayer, 1996;Portable Flexible USB Mini Fan Popular Portable USB Fan Low Power for Xiaomi All Power Supply PC USB Output., 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 (Water Based Emulsion Paint Production Line,1991).Cnm Single Strand Anchor Coupler. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Wisdom LED Floor Lamp, Head Lamp Fabia Mining Lamp,18X16mesh Fiberglass Window Screen Insect Screen,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,Newest Ultra-Long Standby Waterproof Waistband Smart Bracelet with Blood Pressure Heart Rate Monitor and Sport Supervise for for Men and Woman Watch(15ml 18ml Glass Fish Model Perfume Bottle with Plastic Sprayer, 1996). The soluble protein may have commercial use as gelatines,Sterile Dsiposable Syringe for Dental 12ml, peptides or amino acids production (Foldable Bed Military Cot for Camping, 1991;P5 960*960mm LED Display Screen SMD Indoor /Outdoor, 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;2019 New Advertising Inflatables Air Walking Backpack Ball., 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.Side Pack Manual Gas Engine Power Brush Cutter.
