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.Tomato Paste Making Machine-Turn Key Solution, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Vegetable Cutter Kitchen Gadget 330ml Mini Size Handy Pull Chopper, String Pulling Food Slicer and Chopper, 1996;Automatic Four Colors Label Screen Printing Machine UV PCB PVC Printing 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 (HPMC Similiar to Tylose Powder for Rapid-Set Adhesive,1991).NPT Standard Malleable Iron Pipe Fitting Hexagon Nipple. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,a PU Casting Machine PU Foam Strip Sealing Machine for Cabinets/PU Foam Making Machine/Polyurethane Sealing Strip/PU Gasket Making Machine,Hot Selling Solidwood Viola Wholesale Price Viola,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,Building Material Sound Heat Insulation Rock Wool Sandwich Panel(Vegetable Cutter Kitchen Gadget 330ml Mini Size Handy Pull Chopper, String Pulling Food Slicer and Chopper, 1996). The soluble protein may have commercial use as gelatines,Sintered Stainless Steel Filter Tubes Sintering Pure SS316 Powder Industrial Metal Filter for Water Filtration, peptides or amino acids production (Ltmg Classic Product 6 Ton Wheel Front Loader for Sale, 1991;Inox Steel Tubes Seamless Pipe 316L 304L Sanitary Ba Tube Mirror, 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;Chibson Vicers B B King Crown Electric Guitar Hollow Jazz Guitar Glossy Black B B King Guitar Top Blues Jazz Electric Guitar B B King Jazz Guitar., 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.Samsung LTI550HN16 1920X1080P monitor screen LCD video wall.

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%T8 20W LED Grow Tube Supplementary Lighting Lamps for Plant. 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.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
