Bacteria On The International Space Station Are No More Dangerous Than Earthbound Strains

by Keith CowingFebruary 19, 2020

Two particularly tenacious species of bacteria have colonized the potable water dispenser aboard the International Space Station (ISS), but a new study suggests that they are no more dangerous than […]

Clean floating sea foam (Sample 3) was collected directly from the shoreline of the ocean in RI on 23rd December 2023 (left). The wind was from the West. The foam was scooped in a glass bottle, transported to the laboratory, aspirated directly into chloroform in a V-vial and the methanol and water added to give a Folch 2-phase system of chloroform:methanol:water (3.3:2:1). On vortexing, clear vesicles formed at the Folch interphase (right). The vesicles were stable at room temperature for 1-2 weeks. The intact vesicles were analyzed by MALDI mass spectrometry producing from this sample only the 1657-1663 m/z sequence. -- physics.chem-ph
