A comparative analysis of the ultrastructure of hydrocarbon-oxidizing micro-organisms.
The ultrastructure of a variety of micro-organisms was compared after growth on hydrocarbon and non-hydrocarbon substrates. Hydrocarbon-grown organisms were characterized by the presence of intracellular electron-transparent inclusions which in many cases appeared membrane-bound. With one exception, non-hydrocarbon-grown organisms did not contain electron-transparent inclusions. Insignificant amounts of poly-beta-hydroxybutyric acid were produced by the hydrocarbon-grown micro-organisms. After growth on hydrocarbons, all the microorganisms had accumulated varying amounts of the respective unmodified hydrocarbon growth substrate.
