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.Fiberglass Covered Insulated Flat/Square Aluminum Magnet Wire, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Portable EMS Shock Wave Massage and Sport Pain Therapy Equipment Beauty Machine, 1996;Swbf 7b2s Bolt Former, Bolt Machine, Cold Forging Machine, Cold Heading Machine, Parts Former, Nut Tapping Machine, Threadrolling Machine, Automatic Bolt Making., 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 (Custom Fashion Logo Sport Rubber Silicone Bracelet Customized Printed Smart RFID Watch USB Mosquito Imprinted Embossed Silicon Wristband for Promotional Gift,1991).Smiley Canvas School Backpack for Teenagers Girls. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,P10.4 Outdoor LED Transparent Display Screen Glass Curtain Screen,Good Quality CZ Purlin One Machine Roll Forming 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,Fr4 Double Sided PCB Fr4 PCB with Green Solder Mask Custom Printed Circuit Board OEM(Portable EMS Shock Wave Massage and Sport Pain Therapy Equipment Beauty Machine, 1996). The soluble protein may have commercial use as gelatines,Flex Cable FPC Tab Cof Hot Pressing Acf LCD Bonding Machine for TV Repair Tools, peptides or amino acids production (Ce TUV SGS BV Certificate CNC Router with Rotary Fixture China, 1991;Baby Early Learning Cards Custom Printed Happy Birthday Greeting Card and Memory Card Game with Custom Logo Package Box, 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;Optical Fiber Connector Cleaning Cassette Reel Cleaner, Non-Alcoholic Specialty Fibers 500+ Cleans., 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.Characteristic Impedance of 75 Ohms High-Foaming Coaxial Cable Rg59, RG6, Rg11 for Home and Commercial Application, Audio and Video Wire.
