“…Thus, use of crude oil or hydrophobic carbon substrate enrichment can be used as a criterion to isolate new biosurfactant producing bacteria. In many reports crude oil degradation is directly correlated to surfactant production [23,45]. However, a comparative study with hydrocarbon enrichment and without hydrocarbon enrichment is needed to justify the above statement on the use of hydrophobic substrate as a criterion to isolate new biosurfactant producing bacteria.…”

“…It has also been hypothesized that biosurfactants may be used as carbon and energy storage molecules, as a protective mechanism against high ionic strength, or may simply be by products released in response to environmental change (Van Hamme et al, 2006). Rahman, Rahman, Lakshmanaperumalsamy, Marchant, and Banat (2003) studied the distribution of biosurfactant-producing, crude oil-degrading bacteria in oil-contaminated environments. They found that among 32 oil-degrading bacteria isolated from 10 different oil-contaminated sites of gasoline and diesel fuel stations, 80% exhibited biosurfactant production.…”

The activities of man produce significant levels of toxic polycyclic aromatic hydrocarbon compounds (PAHs), which have been identified as excellent candidates for biodegradative removal from contaminated sites. PAHs strongly sorb to soil particles and can also partition into a nonaqueous phase, often limiting bioavailability. In this context, synthetic surfactants and biosurfactants will be discussed as a means to mobilize and solubilize PAHs, potentially increasing bioavailability and subsequent microbial degradation. The fundamentals of bioremediation will be discussed as an important tool that can be used to reduce, remove, or attenuate pollutants at PAH-contaminated sites.

“…Rahman et al (70) investigated the distribution of biosurfactant‐producing and crude‐oil‐degrading bacteria in the oil‐contaminated environment. This research revealed that hydrocarbon‐contaminated sites are the potent sources for oil degraders.…”

Pseudomonas strains are able to biosynthesize rhamnose-containing surfactants also known as rhamnolipids. These surface-active compounds are reviewed with respect to chemical structure, properties, biosynthesis, and physiological role, focusing on their production and the use of low-cost substrates such as wastes from food industries as alternative carbon sources. The use of inexpensive raw materials such as agroindustrial wastes is an attractive strategy to reduce the production costs associated with biosurfactant production and, at same time, contribute to the reduction of environmental impact generated by the discard of residues, and the treatment costs. Carbohydrate-rich substrates generated low rhamnolipid levels, whereas oils and lipid-rich wastes have shown excellent potential as alternative carbon sources.
