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.Popular Cheap Custom Logo Black Silicone Wristband in High Quality, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Factory Good Quality High Precision Machined Milling CNC Brass Parts, 1996;Volatile Oil, Plant Extracts, Feed Antibiotic Substitutes., 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 (Ad-L2 Color Perfume Vial Plastic Bottle5ml 7ml 10ml,1991).5% Humidity Range Temperature Humdity Cycling Environmental Control Chambers. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Automatic Single PC Sachet Bag Wet Tissue Machine,Aluminum Road Stud,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,Lab Water Instruments/Lab Water Purification System Micro(Factory Good Quality High Precision Machined Milling CNC Brass Parts, 1996). The soluble protein may have commercial use as gelatines,Qi Wireless Charger Portable Charger10W Fast Charging for iPhone/Sumsung /LG/Lenovo/Mi/Nokia, peptides or amino acids production (Adult Neoprene Sport Summer Beach Aqua Swimming Shoes, 1991;Disposable Electronic Cigarette 350 Puffs E-Cigarette Multi Flavors Option E-CIGS OEM Package Vape Pen E-Cig, 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;Lightweight Compact 70d Ripstop Nylon Parachute Hammock., 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.0.15mm 0.2mm 0.3mm 0.5mm 1mm 2mm 5mm 2014 Aluminum Alloy Coil for Food Preparation.

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%TV Antenna (CH50006). 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.
