Abstract

Nostoc muscorum could grow heterotrophically and successfully utilized a number of different sugars. Glucose proved to be the best sugar tested for growth and nitrogen fixation. However, citrate was outstanding among the different organic acids tried in allowing a substantial algal growth and consequently a high amounts of fixed nitrogen. The chemical analysis of the algal cells as well as the culture filtrate revealed the presence of various amino acids as well as auxine like substances.
