Abstract Diesel contamination is becoming a global concern especially for the marine environment. Several techniques have been applied to clean up this pollution, but most of them are not environmentally friendly. Biodegradation provides an environmentally friendly, effective and affordable technological solution for treating diesel contamination and to remove toxic hydrocarbons from contaminated environments. Discussion on diesel characteristics, environmental and health effects, the efficiency of biodegradation by bacteria, advantages, and limitations of diesel biodegradation from past and current researches are intensively discussed in this paper. Factors affecting diesel biodegradation including oxygen availability, salinity level, pH, diesel bioavailability, temperature, nutrient availability and bacterial species are comprehensively elaborated. This paper presents intercorrelated discussion of bacterial species and diesel bioavailability as the major factor that affect the biodegradation performance. In addition, some potential bacterial species which are proven to be effective in diesel biodegradation are highlighted in this review paper. This paper also provides a discussion of the forthcoming prospects of diesel biodegradation in various contaminated environments related to the possibility of anaerobic biodegradation, selection of superior bacteria and the interfere of specific bacterial enzyme in diesel biodegradation.
