This Newsbrief deals with a new procedure for cleaning up oil pollution from the ocean — a biological solution that uses microbes to digest dispersed oil. In terms of the Atlas of Technological Megatrends it is concerned with the functionality of matter processing.
Technoscan® Newsbrief, Vol. 5, No. 5, of May 31, 2010, dealt with oil-spill remediation and the accident in the Gulf of Mexico. It pointed out the three principle approaches involved:
  • Biological - in which the oil is digested by organisms
  • Chemical - in which oil is burnt or diluted with dispersants
  • Mechanical - in which oil is physically gathered and recovered
Efforts involving microbes, i.e., the first approach, have been pursued for many years. In the fifties and sixties the emphasis was on microbe selection and breeding involving reactors called chemostats. With the advent of genetic manipulation in the seventies and eighties the emphasis changed to genetic improvement of microbes. This proved to be a big challenge. Many genetically enhanced microbes tended to be fragile and had difficulty in surviving in challenging oceanic conditions.
Recent years have seen the re-emergence of selection and breeding using more sophisticated approaches called bio-augmentation. This was reinforced by news reports describing the apparent rapid clean-up in the Gulf, ascribing it to naturally occurring microbes. A number of competing approaches were brought to public attention. Different microbes have been identified, e.g., Alcanivorax borkumensis, as well as different procedures from companies in the USA and abroad.
However most of these have not advanced beyond Technology Readiness Level (TRL) 6, on NASA’s nine point scale. Further development is expected.
