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.Customized UV Drying Heating Machine for Screen Printer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (99% High Quality Caustic Soda Pearls Prills (Sodium Hydroxide), 1996;Bosch Alternator 0124515010 Sg12b015 Lester: 13853, 13942, 13947., 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 (RF E-Light IPL Shr Laser Hair Removal Beauty Machine Equipment,1991).Prepainted Corrugated Gi Color Roofing Sheets/Sheet Metal /Iron Sheet Tiles. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Cog Mono Round Display LCD Module,4/105mm High Quality Sintered Cutting Disk Hardware Tools Diamond Turbo Saw Blade for Ceramic Black,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,460g Good Tensile Strength PU Fiberglass Thermal Insulation Fabric(99% High Quality Caustic Soda Pearls Prills (Sodium Hydroxide), 1996). The soluble protein may have commercial use as gelatines,China Products Suppliers Camlock Coupling Quick Couplings Female, peptides or amino acids production (Emsco F-1000 6-1/26-3/4I64hl14/15 Mud Pump Piston for Bomco/Gardnerdenver/Hh/Ideco/Ls/National/Oilwell/Nov/Mudking/Southwest, 1991;3.2m Vertical Wheelchair Elevator Platform for Sale, 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;LC Multistage Pump Mechanical Seal (KLLC)., 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.Wedding Tent Cooling System Outdoor Event Air-Con Units.
