[Lipid and gramicidin C biosynthesis in Bacillus brevis during stab cultivation]

The content of lipids was studied in the gramicidin producing variants of Bacillus brevis var. G.-B. in the process of submerged cultivation. The greatest accumulation of lipids preceded the highest content of gramicidin C in the producing cells. The interrelation between the synthesis of lipids and that of gramicidin C is discussed.
