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.Ss 5 Micron Sinter Powder Liquid Cartridge Filter Stainless Steel Metal Water Filter with M20 M30 M40 Thread Connector, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Firefighting Equipment Aluminum Rescue Tripod with Winch 30m, 1996;Rotor Disc Brake Pad Repair Kit for Wva 29087/29202/29253/29279., 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 (Non-Deformation Kitchen Cleaning Sponge Mesh Sponge Scourer,1991).Automatic Controller Carbon Steel Sheet Pipe China CNC Plasma Cutter. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Cjx2-F (LC1-F) AC Magnetic Contactor,30W Portable Vehicle Bomb Moving Signal Jammer for GSM/2g/3G/4G Cellular GPS WiFi Signal,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,Handmade Stainless Steel Irregular Kitchen Sink Bowl (DF5545XH)(Firefighting Equipment Aluminum Rescue Tripod with Winch 30m, 1996). The soluble protein may have commercial use as gelatines,Fj22082mabts 225mm 220V AC Power Amplifier Cooling Fan, peptides or amino acids production (Aluminum/Aluminium Extrusion Profile Housing for LED Light, 1991;Flexible Stand up USB Charging Stands Cable Phone Charger Holder for Apple iPhone Samsung Huawei Android Phone Holders P0.11, 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;Single Mode Sc/APC Simplex Fiber Optic Adapter., 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.120da 3-32V DC Output 24~480VAC High Voltage Single Phase Solid State Relay.
