Knowledge on the biodegradation of hydrocarbons in soil

Research gap analysis derived from 3 agriculture papers in our local library.

The gap

There is a lack of knowledge on the biodegradation of hydrocarbons in soil. The complexity of the problem makes it difficult to study. There is a need for more research on the kinetic models applicable to this process.

Evidence profile

Sourced from the stated challenges and stated research gap and future-work section of the source papers, classified as general, drawn from work published between 1975 and 2026, spanning 3 journals. Those papers have been cited 25 times in total.

    Further studies are needed to determine the long-term effects of the bioremediation method. The application of the method to other types of contaminated soils should be investigated. The identification of other bacterial strains associated with the biodegradation of petroleum-derived hydrocarbons is necessary.
