Predatory bacteria bite their own | Lawrence Livermore National Laboratory

May 4, 2021
Predatory bacteria bacteria that eat other bacteria use approaches remarkably similar to much larger organisms as they target their prey. In the case of
Vampirovibrio, the bacterium attaches to the outside of a prey cell and feeds on its interior cytosol much as a vampire bat sucks blood from mammals it feeds on. For bacteria in the genus
Lysobacter, several bacterial cells act as a group to hunt their prey, just as a wolf pack might target an elk. Image courtesy of Northern Arizona University. (Download Image)

In wild soil, predatory bacteria grow faster than their prey

E-Mail
Predatory bacteria bacteria that eat other bacteria grow faster and consume more resources than non-predators in the same soil, according to a new study out this week from Northern Arizona University. These active predators, which use wolfpack-like behavior, enzymes, and cytoskeletal fangs to hunt and feast on other bacteria, wield important power in determining where soil nutrients go. The results of the study, published in the journal
mBio this week, show predation is an important dynamic in the wild microbial realm, and suggest that these predators play an outsized role in how elements are stored in or released from soil.
Like every other life form on earth, bacteria belong to intricate food webs in which organisms are connected to one another by whom they consume and how. In macro webs, ecologists have long understood that when resources like grass and shrubs are added to lower levels of the web, predators at the top, such as wolves, often benefit. The ....

Three Lawrence Livermore National Laboratory (LLNL) postdoctoral appointees have been selected to attend the 70
th annual Lindau Nobel Laureate meeting in Germany this June thanks to the University of California President’s 2021 Lindau Nobel Laureate Meetings Fellows Program. The three selected to attend the meeting are Oluwatomi (Tomi) Akindele, Matthew Edwards and Wei Jia Ong.
The Lindau Nobel Laureate meeting is an international scientific forum that provides an opportunity for about 600 students and postdocs from around the world to meet with 30 to 40 Nobel laureates. The meeting is intended to foster an exchange among scientists of different generations, cultures and dis ....
