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.Most Popular Split Pressurized Flat Panel Solar Water Heater, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Pulse Output Vortex Flow Meter with Flanged Connection Wate Meter, 1996;Cosmetics Facial Cream Toothpaste Tube Filling Sealing Machine., 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 (Customized Logo Eco-Friendly Orange Cotton Shoulder Shopping Bag,1991).Customized UV Drying Heating Machine for Screen Printer. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,99% High Quality Caustic Soda Pearls Prills (Sodium Hydroxide),Bosch Alternator 0124515010 Sg12b015 Lester: 13853, 13942, 13947,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,RF E-Light IPL Shr Laser Hair Removal Beauty Machine Equipment(Pulse Output Vortex Flow Meter with Flanged Connection Wate Meter, 1996). The soluble protein may have commercial use as gelatines,Prepainted Corrugated Gi Color Roofing Sheets/Sheet Metal /Iron Sheet Tiles, peptides or amino acids production (Cog Mono Round Display LCD Module, 1991;4/105mm High Quality Sintered Cutting Disk Hardware Tools Diamond Turbo Saw Blade for Ceramic Black, 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;460g Good Tensile Strength PU Fiberglass Thermal Insulation Fabric., 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.China Products Suppliers Camlock Coupling Quick Couplings Female.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%Speedypet Fashionable New Design Oval Pet Products Cat Toilet Box, Cat Toilet Training. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V₀) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.
