Marine bacteria can degrade phytol into various isoprenoid acids. One C(17) acid, potentially indicating sedimentary conditions, arises from bacterial metabolism of an abiologically produced ketone.

Area of Science:

  • Microbiology
  • Organic Geochemistry
  • Environmental Science

Background:

  • Phytol degradation by microbes is a proposed source of sedimentary acyclic isoprenoid acids.
  • Limited bacterial cultures have previously yielded identified isoprenoid acids from phytol growth.

Purpose of the Study:

  • To investigate microbial degradation pathways of phytol by marine bacteria.
  • To identify and characterize isoprenoid acids produced from phytol as a sole carbon source.

Main Methods:

  • Culturing marine bacteria with phytol as the sole carbon source.
  • Detailed capillary gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) analyses of metabolic products.

Main Results:

  • Two bacterial strains oxidized phytol to phytenic acid but showed no further degradation.

  • A third bacterial isolate produced a mixture of five saturated isoprenoid acids from phytol.
  • A C(17) isoprenoid acid was identified, likely originating from bacterial metabolism of an abiologically produced C(18) isoprenoid ketone.

    • Conclusions:

    • Bacterial metabolism of phytol yields diverse isoprenoid acids.
    • The C(17) isoprenoid acid's formation suggests a link between microbial activity and abiotic processes.
    • The abundance of this C(17) acid may serve as a sensitive indicator of sedimentary depositional environments.
