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.Sfj-250r Vibrating Automatic Powder Sieve Machine with Cycling and Recovery System Replace Gema, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Tungsten Solid Carbide Straight 4/6 Flutes Reamer, 1996;China Quality Heavy Duty Globe Control Valve., 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 Wire Harness for Various Application,1991).Cheap CNC Spindle Peeling Lathe for Steel Bar. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Nonwoven Glassfibre Laid Scrim for Automotives - Reinforcements for Sound Absorption Elements,3 Years Warranty 3.2V 60ah 75ah 86ah 100ah 110ah 200ah Single LiFePO4 Battery Cell LiFePO4 Lithium Iron Phosphate Battery Cell for EV, E-Cars with Grade a,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,6063 Series Aluminium Extrusion Pipe in Hot Sell Made in China(Tungsten Solid Carbide Straight 4/6 Flutes Reamer, 1996). The soluble protein may have commercial use as gelatines,Sc LC FC St Fiber Optical Adaptor Coupler Adapter, peptides or amino acids production (Ent Treatment Medical Chair with Foot Control, 1991;Quality Automatic High Speed Iron Wire Nail Concrete Steel Nail Forming Machine/Coil Nail Machine and Nail Thread Rolling Machine/Nail Twisting Machine, 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;New Leaf Shape Pearl Jewelry Wedding Tiara., 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.Starter Motor 0001367034 12V 3KW 9T for Mercedes.

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%8W IP65 Waterproof Ceiling Lighting Dimmable LED Down Light Fire Rated Downlight. 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.
