The reaction conditions for the maximal production of 10-hydroxystearic acid from oleic acid by whole cells of Stenotrophomonas nitritireducens were determined as pH 7.5 and 35°C with 0.05% Tween 80. Whole cells of 20 g/L converted all of 30 g/L oleic acid into 10-hydroxystearic acid without detectable byproduct after 4 h under anaerobic conditions, whereas the cells converted 30 g/L oleic acid into 20 g/L 10-hydroxystearic acid with a yield 67% after 3 h under aerobic conditions. These results indicated that anaerobic conditions were more suitable for the production of 10-hydroxystearic acid from oleic acid.
Whole cells of S. nitritireducens exhibited the highest productivity and yield of 10-hydroxystearic acid from oleic acid among the previously reported studies
