The microbe behind the masterpiece: janthinobacterium lividum. deadline for the 2019 asm agar art contest is oct. 22! http://ow.ly/sg7f50wdz8k
maybe orange and red microbes are just too #basic for you. janthinobacterium lividum, which makes the pigment violacein, is decidedly more dramatic in colors ranging from dark purple to darkdarkdarkdarkdark purple (aka black). it's commonly found in soil and water and is considered an endophyte - that is, a non-pathogenic member of various plant species' microbiomes. but this bacterium's real claim to fame is its mutualistic relationship with amphibians. it colonizes amphibians' skin and protects them from the otherwise deadly fungal pathogen, batrachochytrium dendrobatidis. turns out that violacein and another j. lividum-made compound, indole-3-carboxaldehyde, have antifungal activity. crude j. lividum cell extract also shows antibacterial activity against #mrsa, vre and other drug-resistant bacterial pathogens. in experiments, it was so effective that researchers floated the idea of using j. lividum extract to k**l drug-resistant pathogens during wastewater treatment. .
camilla fagorzi, carolina chiellini and renato fani used janthinobacterium lividum for the city skyline in ''bacterial endophytes celebrating the beauty of florence,'' 2017.
