Microbial degradation of petroleum

Abstract: A process for the microbial degradation of petroleum or oily waste materials which comprises treating the petroleum or oily waste with a strain of Candida lipolytica for a sufficient time until degradation has been achieved. The microorganism strains employed have a broad spectrum of degradation capability and are capable of degrading crude petroleum as well as a variety of organic molecules, including aliphatic, aromatic and heterocyclic compounds.

Microbial degradation of polychlorinated biphenyls

Abstract: A process for the microbial degradation of polychlorinated biphenyls (PCBs) which comprises treating the PCBs with certain non-pathogenic, hydrocarbon-utilizing strains of Cladosporium cladosporioides, Candida lipolytica, Nocardia globerula, Nocardia rubra and/or Saccharomyces cerevisiae until the PCBs have been substantially degraded. The process is applicable degrading PCBs as they may be present as pollutants or contaminants in water, in industrial effluents, in various land areas such as industrial sites and the like or in varied laboratory or commercial installations. The process may also be used to clean up and degrade mixtures of PCBs and various hydrocarbon oils or petrochemicals whenever their presence constitutes a deleterious pollution.
