Abstract |
A bacterium which can utilize malonate as a sole carbon source was isolated from soil. This strain was identified to be Acinetobacter calcoaceticus by morphological, cultural, phtsiological and biochemical examination. When this microorganism was grown on malonate as a sole carbon source, the enzymes, such as malonyl-CoA synthetase, isocitrate lyase and malate synthase were induced. These results suggest that in this microorganism, malonate is also assimilated through the proposed pathway in Pseudomonas fluorescens: malonate → malonyl → CoA → acetyl → CoA → glyoxylate cycle. |
