“…The bacterium Rhodococcus sp. ITR03 was reported to produce biosurfactants (trehalolipid and rhamnolipid) as well as degrade DDT residues and chlorinated aromatic compounds [51]. Thus, the results indicate that both bacteria, P. aeruginosa and B. subtilis, had the ability to degrade DDT in addition to producing biosurfactants.…”

DDT (1,1,1-trichloro-2,2-(4-chlorophenyl) ethane) is one of the organic synthetic pesticides that has many negative effects for human health and the environment. The purpose of this study was to investigate the synergistic effect of mixed cutures of white-rot fungus, , and biosurfactant-producing bacteria, and , on DDT biodegradation. Bacteria were added into the culture (mycelial wet weight on average by 8.53 g) in concentrations of 1, 3, 5, and 10 ml (1 ml ≈ 1.25 × 10 bacteria cells/ml culture). DDT was degraded to approximately 19% by during the 7-day incubation period. The principal result of this study was that the addition of 3 ml of into culture gave the highest DDT degradation rate (approximately 86%) during the 7-day incubation period. This mixed culture combination of the fungus and bacteria also gave the best ratio of optimization of 1.91. DDD (1,1-dichloro-2,2-(4-chlorophenyl) ethane), DDE (1,1-dichloro-2,2-(4-chlorophenyl) ethylene), and DDMU (1-chloro-2,2-(4-chlorophenyl) ethylene) were detected as metabolic products from the DDT degradation by and. The results of this study indicate that has a synergistic relationship with and can be used to optimize the degradation of DDT by .

“…DDT, the first synthetic insecticide, was widely marketed and applied in the 1950s and 1960s. Its use was prohibited in most countries starting in the early 1970s because of its toxicity, hydrophobicity, and bioaccumulation (Bajaj et al, 2014;Kannan et al, 1992;Kelce et al, 1995;Purnomo et al, 2011). DDT is an organic compound with low solubility and high chemical stability, composed of chlorinated aliphatic and aromatic structures.…”

The environment pollution with hydrophobic hydrocarbons is a serious problem that requires development of efficient strategies that would lead to bioremediation of contaminated areas. One of the common methods used for enhancement of biodegradation of pollutants is the addition of biosurfactants. Several mechanisms have been postulated as responsible for hydrocarbons bioavailability enhancement with biosurfactants. They include solubilization and desorption of pollutants as well as modification of bacteria cell surface properties. The presented review contains a wide discussion of these mechanisms in the context of alteration of bioremediation efficiency with biosurfactants. It brings new light to such a complex and important issue.
