The naringinase was from a newly isolated strain of Bacillus amyloliquefaciens 11568.
The nariginase is a single protein with α-class="smallcaps">l-rhamnosidase and β-class="smallcaps">d-glucosidase activity.
Several flavonoids could be transformed by the naringinase.
The naringin in citrus juice could be efficiently hydrolyzed by the naringinase.
