WE have reported the isolation and partial characterization of a novel lipophilic glycoside which is apparently specific to nitrogen-fixing blue-green algae1. During these studies we noticed that a culture of Mastigocladus laminosus which had been grown in a medium containing ammonium salts synthesized no detectable quantities of the glycoside. More recently we have observed that the glycoside is nevertheless present when this organism is cultured on a medium containing no combined nitrogen… CONTINUE READING
