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.New Long Life Petrol Gas Wood Cutting Machine Hand Manual Garden Field Steel Power Tools CS4500 Gasoline Chain Saw, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Custom Logo Various Flavor 500puffs E-Cigarette Disposable Electronic Cigarette, 1996;Ep/ Nn/Chevron Heat Resistant Conveyor Belt Rubber Conveyor Belt., 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 (25ton LPG Tank Trailer LPG Semi Trailer LPG Gas Tank for Zimbabwe,1991).Large Size Stone Aluminum Honeycomb Panel for Facade. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Outdoor Show Audio Vera12+ Upgraded Passive Line Array Speaker System,Socket Type 2 32A 22kw Three Phase EV Charging Point EV Charger for Electric Vehicle Smart Charging,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,Making Machine for EVA Soft Hose(Custom Logo Various Flavor 500puffs E-Cigarette Disposable Electronic Cigarette, 1996). The soluble protein may have commercial use as gelatines,Cummins Diesel Engine ISM11 Qsm11 Fuel Injector Repair Rebuilt Parts Injector Cup Nozzle 4903474, peptides or amino acids production (High Efficiency Air Cooled Air Source Water Chiller Heat Pump, 1991;Building Material Acrylic Solid Surface Stone Sheet for Wall Tile Countertop Table Top, 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;12oz 16oz Glass Mason Jar with Handle and Straw., 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.Mini Freeze Dryer for Sale.

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%PA PC PBT Pet Plastic Svmd 3-in-1 Dehumidifying Dryer. 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.
