Tyrosinases, bifunctional metalloenzymes, catalyze the oxidation of monophenols and o-diphenols to o-quinones, the precursor compounds of the brown-coloured pigment melanin. In eukaryotic organisms, tyrosinases are expressed as latent zymogens that have to be proteolytically cleaved in order to form highly active enzymes. This activation mechanism, known as the tyrosinase maturation process, ha...

An in vitro study was conducted to know the veridical properties of silver nanoparticles synthesized from   locally available white button mushrooms (Agaricus bisporus). The characterized colloidal silver nanoparticles exhibited as an excellent virucidal property on viral strain Bacteriophage. The viral inactivation process was increased with increasing the concentration of colloidal s...

Agaricus bisporus mushrooms are well known for their nutritional and medicinal values. A. bisporus is a source of protein (about 40% on a dry basis), ergosterol, several minerals, carbohydrate, and fat. The present study was conducted to investigate the effect of A. bisporus S-II extracts on human pathogenic bacteria in-vitro condition. Totally, thre...

© 2011 VÚP Food Research Institute, Bratislava 167 Edible mushrooms are widely consumed in many parts of the world owing to their characteristic taste, aroma and nutritional relevance. Edible mushrooms are valuable components of diet and their culinary and commercial values are mainly due to their organoleptic properties such as texture and flavour [1, 2]. They also are excellent source of seve...
