Nostoc sp. colonies from field collections were cultured and propagated on silica sand with aqueous N-free BG-11 medium. Laboratory experiments were conducted to characterize the in vivo freeze-recovery physiology of nitrogenase activity. Nitrogenase activity was monitored by the acetylene reduction technique. Frozen Nostoc sp. colonies were thawed and… CONTINUE READING
