Vibrio natriegens is a
Aquaculture and antibiotic resistance
Many strains of Vibrio, including natriegens, are pathogenic against farmed aquacultures such as the abalone and have recently resulted in destruction of farmed abalones when aquacultures get infected.[9] In response, fishers have taken to inoculating tanks with large amounts of antibiotics, which has resulted in Vibrio natriegens developing a potent antibiotic resistance to many drugs. In a recent study, the AbY-1805 strain of Vibrio natriegens was shown to be completely resistant against 17 of the 32 tested antibiotics and at least partially resistant against 22 of the 32.[10]

Biotechnological uses
Owing to its rapid growth rate, ability to grow on inexpensive carbon sources, and capacity to secrete proteins into the growth media, efforts are underway to leverage this species as a host for molecular biology and biotechnology applications.[11][12] Recently, V. natriegens crude extract has been shown by multiple research groups to be a promising platform for cell-free expression.[13][14][15][16] Scientists are also hoping that Vibrio natriegens, with its incredible growth speed, will make microbial experiments in outer space, where time is an extremely valuable asset, much quicker. Interestingly, it has been shown that Vibrio natriegens, despite its incredibly quick doubling speed on Earth, might grow even faster in space. A recent experiment displayed that after 24 hours of growth the Vibrio cells grown in zero gravity were 60 times denser than those grown in full gravity, possibly attributable to an extended exponential growth phase in low-gravity conditions.[17]
