The mucilage formed by growth of Acetomonas on a medium containing sucrose has been isolated and purified. Partial hydrolysis, methylation followed by hydrolysis, periodate oxidation and optical rotation of the product and its methylated derivative showed it to be a 2β,6′‐linked levan having branch points with 2β,1′ linkage and an average unit chain of 12 anhydrofructofuranose residues; the molecular weight was of the order of several hundred thousand. In this property of levan formation, Acetomonas resembles the related genus Pseudomonas and differs from the dextran‐forming genus Acetobacter .
