  • Both saturated and unsaturated hydrocarbons are subjected to microbial degradation.
  • The later one (unsaturated) is more easily degraded than the former (saturated).
  • The branched compound exhibits a greater susceptibility to the action of microbial enzymes when compared to straight chain hydrocarbon. Methane, Ethane, Propane, Butane, pentane, hexane & many other aliphatic hydrocarbons are subjected to microbial degradation.
  • Metabolism of Ethane is done by the species of Mycobacterium; Nocardia, Streptomycetes, Pseudomonas, Flavobacterium and several fungi.
  • High molecular wt. aliphatic hydrocarbons are degraded by a variety of micro-organisms including Nocardia, Pseudomonas, Streptomycetes, Desulphovibrio, Corynebacterium and many fungi.
  • The scheme for the degradation of aliphatic hydrocarbon is as follows.

No description available.

Where, X = Substitution group

First ‘X’ is deleted from the chain

If ‘X’ is chlorine→ pesticide is subjected to dehalogenation (Anaerobic)

I.e. R-CH2CH2-X

Where; Pseudomonas putida contains dehalogenase enzyme
