Pseudomonas aeruginosa and Bacillus megaterium. P. aeruginosa has the ability to corrode stainless steel and presents a challenge for the longevity of pipelines and other metal-based infrastructure, while B. megaterium, can decompose hydrocarbons — the basis for oil.
Sánchez, along with one of his collaborators, Zacariah Hildenbrand, Ph.D., a UTEP alum, were inspired to use bacteriophages based on their applications in the medical industry, where they are used to combat infections caused by multi-drug resistant bacteria.
“Since the bacteria are living organisms, over time they developed a resistance, in the form of a less penetrable membrane, to traditional disinfectants,” Sánchez explained. “But the bacteriophages, which are viruses themselves, attach to specific receptors on the surface of the host cell and evolve alongside the bacteria they are trying to infect, meaning that any resistance acquired by the bacteria triggers the modification of bacteriophages to keep the infection going.”
