My PhD-related project “Fungi in Space” is on Researchgate ( ) where I will be posting the conference posters and presentations related to my research. Bellow you can find more information on other projects (including real Space projects! :p).

Biofilm Formation in Space (BFS)

I am happy to share with you my first space project called “Biofilm Formation in Space (BFS)” scheduled to launch to the International Space Station (ISS) late 2018 / early 2019 on SpaceX CRS-16 (or Spx-16).

  • Funding agency: NASA
  • Principal Investigator (PI): Luis Zea

Biofilms are complex, resistant structures formed by microorganisms: from bacteria to fungi. These biofilms are found almost everywhere on Earth: on our teeth, in water systems, in medical instruments, on our bathtubs, etc.  Biofilms were also found aboard the ISS: either contaminating their onboard-grown lettuce or clogging the urinal-recycling system.

Goal:  In a long-term space mission, it would be desirable that biofilms can be monitored and controlled, of course to reduce systems maintenance and increase efficiency and reliability!

Two main “space microbes” that form biofilms will be studied: Pseudomonas aeruginosa, –a Gram-negative bacteria; and Penicillium rubens (or Penicillium chrysogenum) – a filamentous fungi.

The science part will mainly consist on 1) growing the organisms on the ISS where they will be exposed to microgravity (or near weightlessness) and on Earth, where they are exposed to normal 1g gravity. 2) characterizing biofilm growth both in a morphological and genetic level.
