## 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

## Abstract Growth and fixation of nitrogen were retarded in __Anabaena doliolum__ when grown on elemental nitrogen in presence of four different herbicides. The alga was found to be intolerant to these chemicals under nitrogen fixing conditions even in low concentrations. An inhibition of photosyn
