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.En71 Approval Hand Contral Plastic Fan Mini Fan for Summer (10189692), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (LED Assembly Wave Soldering Machine Price, SMT Machine Wave Soldering, 1996;PE Jacket Sm G652D 12 Fibers Armored Fiber Optic Cable., 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 (3D CAD Engineering Metal High Precision Auto Parts CNC Machining Parts,1991).Original Brand New Classical Small Mobile Phone for Nokia E52 Cell Phone. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,China OEM Customized Household Appliance Fan Molding Humidifier Plastic Injection Mold Mould Maker,Stainless Steel Fruit Seed Extractor Fruit Seed Remove Machine Passion Fruit Pulping Machine,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,4G Body Worn Camera Ambarella IP67 Frame Rate 1080P@30fps/720p@30fps(LED Assembly Wave Soldering Machine Price, SMT Machine Wave Soldering, 1996). The soluble protein may have commercial use as gelatines,Best Price Aluminium Sulphate for Water Treatment, peptides or amino acids production (Hot Sale Loading Truck with Cummins Engine, 1991;Solid Surface Lowes Bathroom Countertops/Acrylic Solid Surface Sheets, 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;50kg Soya Bean Seed PP Woven Bags Sacks., 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.Iron Wire Dry Type Straight Line Wire Drawing Machine.
