Kasthuri Venkateswaran, 2021, "Genomic characterization of plant-growth promoting features of Sphingomonas strains isolated from the International Space Station, with an emphasis on phytohormone production", https://doi.org/10.48577/jpl.YNCNUC, msphere, JPL Open Repository
AbstractIn an ongoing microbial tracking investigation of the International Space Station (ISS), several Sphingomonas strains were isolated. Phylogenetic analysis, based on the 16S rRNA gene sequence, identified the ISS strains as S. sanguinis (n=2) and one strain isolated from t... |

Parker, Ceth W, 2021, "Genomic characterization of Parengyodontium torokii sp. nov., a biofilm-forming fungus isolated from Mars 2020 assembly facility", https://doi.org/10.48577/jpl.POWEDU, Journal of Fungi, JPL Open Repository
A fungal strain (FJII-L10-SW-P1) was isolated from the Mars 2020 spacecraft assembly facility and exhibited biofilm formation on spacecraft-qualified Teflon surfaces. The reconstruction of a five loci gene tree (ITS, LSU, SSU, RPB1 &2, and TEF1) using multi-locus sequence typing... |

Urbaniak, Camilla, 2021, "Simulated microgravity promotes horizontal gene transfer of antimicrobial resistance genes between bacterial genera in the absence of antibiotic selective pressure", https://doi.org/10.48577/jpl.6JJ1KK, Frontiers in Microbiology, JPL Open Repository
Bacteria are able to adapt and survive in harsh and changing environments through many mechanisms, with one of them being horizontal gene transfer (HGT). This process is one of the leading culprits in the spread of antimicrobial resistance within bacterial communities and could p... |
