Production of chitosan from endolichenic fungi isolated from mangrove environment and its antagonistic activity
Objective:To screen the chitosan producing ability of endolichenic fungi and its antibacterial activity.Methods:Lichen collected from mangroves was screened for endophytes and the chitosan producing ability of endolichenic fungi by submerged fermentation was also determined.Antibacterial activity wa...
