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.Creative New Product Coin Holder Keychain, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Auto Ignition Coil for Germany Car 330905115A 330900115A 0221502007 0221502008, 1996;Weak Daylight Recharge All in One Solar Street Light., 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 (Ybz16-150/140 Vane Steering Hydraulic Pump,1991).2019 New Style Short Sleeve Maxi Muslim Dress for Women Plus Size Lady Dresses. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,3mm Indoor Wall Cladding Decoration Aluminum Composite Material,240*375*25mm Rectangle Galvanized Steel Access Panel for Air Duct Maintenance Cleaning,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 CNC PU Sandal Pouring Machine(Auto Ignition Coil for Germany Car 330905115A 330900115A 0221502007 0221502008, 1996). The soluble protein may have commercial use as gelatines,Glass Disc Suspension Insulators, peptides or amino acids production (2 Kw Steam Turbine Generator Stainsteel Steel Steam Generator, 1991;Green Refillable Bottles Vial with Glass Dropper for Essential Oil Perfume Cosmetic, 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;Polypropylene Fibre for Commercial Slabs., 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.Compatible 1000base-Bx Bidi SFP 1490nm-Tx/1310nm-Rx 20km Dom Transceiver Module.
