Interpretive Summary:

Technical Abstract: Triacylglycerols (TAG) containing hydroxy fatty acids have many industrial uses, such as the manufacture of aviation lubricants, plastics, paints, nylons and cosmetics, because of the hydroxyl groups on the fatty acid (FA) constituents. Diacylglycerols (DAG) containing hydroxy FA can also be used in the above mentioned industries. Soy-polyols (oxygenated TAG) are important starting materials for the manufacture of polymers such as polyurethane. Recently we developed a new method to screen microorganisms for the direct production of polyol oils from soybean oil. Of the 650 cultures screened, 50 were active in converting soybean oil to polyol oil and DAGs products. These 11 most active strains were identified based on the 16S rRNA sequences, and two strains were identified as Acinetobacter haemolyticus and the remaining strains belonged to the genus Pseudomonas.
