Metal removal capability of two cyanobacterial species in autotrophic and mixotrophic mode of nutrition

Highlight Mixotrophic conditions can be used to optimize the biosorption controllable factors for the maximum metal removal efficiency. Different habitats (lime stones of Khuzestan province and fresh water of of Golestan province) can effect the uptake of heavy metal by two Nostoc species (Nostoc sp. N27P72 and Nostoc sp. FB71). Modification of culture media can maximize the uptake capacity of the heavy metal ions by two Nostoc species.
