Environmental pollution associated with the petroleum industry is a major problem worldwide. Microbial degradation is extremely important whether in the extractive process or in bioremediation of contaminants. Assessing the local microbiota and its potential for degradation is crucial for implementing effective bioremediation strategies.

- * Rhamnolipids, which are produced by P. aeruginosa, are important for these behaviors, but their biochemical mechanisms and the genes involved have not been thoroughly examined until now.
- * Using DNA microarrays, researchers found 134 genes with different expression levels between normal bacteria and a mutant that can't produce rhamnolipids, revealing that these compounds significantly influence gene expression and enable swarming motility.
Burkholderia harbors versatile Gram-negative species and is β-Proteobacteria. Recently, it was proposed to split the genus in two main branches: one of animal and plant pathogens and another, Paraburkholderia, harboring environmental and plant-beneficial species. Currently, Paraburkholderia comprises more than 70 species with ability to occupy very diverse environmental niches.
