Technical Abstract: Fifty-eight strains of eight Bacillus species were selected from the ARS Culture Collection to investigate their ability to bioconvert oleic acid to unique hydroxy or keto derivatives. Addition of 0.5% oleic acid substrate to a whole-cell culture of Bacillus strain NRRL BD-447 produced mixtures of mono-, di- and tri-substituted compounds. These products appear to contain combinations of keto- and hydroxy- groups. One of the major products, 7-hydroxy-16- keto-9-octadecenoic acid, was isolated by HPLC and its structure determined by GC-MS and NMR. Isolation and identification of other major products is described.
