<i>Musa paradisiaca </i>stem juice as a source of peroxidase and ligninperoxidase
1036-1040Musa paradisiaca stem juice has been shown
to contain peroxidase activity of the order of 0.1 enzyme unit /ml. The Kill values
of this peroxidase for the substrates guaiacol and hydrogen peroxide are 2.4
and 0.28 mM respectively. The pH and temperature optima arc 4.5 and
62.5°C respectively. Like other peroxidases, it follows double displacement type
mechanism. At low pH, Musa paradisiaca stem juice exhibits ligninperoxidase
type activity. The pH optimum for ligninperoxidase type activity is 2.0
and the temperature optimum is 24°C. The Km values for veratryl
alcohol and n-propanol are 66 and 78 μM respectively
