During her work at Rutgers University microbiologist Elizabeth Bugie (1920-2001) was involved in the discovery of streptomycin, the first antibiotic effective against tuberculosis. While her boss received the Nobel Prize for this discovery, she wasn’t mentioned. Honouring her work on the discovery and evaluation of antibiotics, DSMZ researchers named the strain Streptomyces bugieae (DSM 41528) after her.

Fanny Hesse (1850-1934) worked unpaid for her husband Walter Hesse in Robert Koch's laboratory. Koch was desperate to find a suitable medium for growing bacterial cultures. Fanny Hesse came up with the idea of using agar, which proved to be an ideal gelling agent. To honour her for introducing agar and revolutionising microbiology, DSMZ researchers named the strain Streptomyces hesseae (DSM 40473) after her.

Hi all 👋
I'm a #microbiology researcher working with #Antarctic soil microbes, mainly #Streptomyces and #fungi, with an aim to find new #antibiotics or other #NaturalProducts.

I love photographing microbes and will mostly be posting colony pics and #microscopy.

Otherwise, you can find me lurking around posts about #science, #politics, #health, #dataviz, #climatechange, #socialjustice and #undergroundmusic

#Plastic-eating #fungi thriving in man-made '#plastisphere' may help tackle global #waste.

Researchers from the University of Tsukuba find that #Streptomyces phage tail-like particles are located intracellularly, unlike other contractile #injections systems, and protect the #bacterium against #osmotic #stress

Another Contractile Injection System? 💉🙄 BUT THIS is a special one 👈😱 Spearheaded by our postdoc @casub1 in a fantastic collab with @JWSallmenII & @SusanSchlimpert, they could demonstrate a cytoplasmic role (☠️) of CIS in #Streptomyces out now in @NatureMicrobiol 🧵1/2

A computational model of #Streptomyces reveals that if antibiotic production trades off with replication, genome architecture can evolve to support a mutation-driven division of labor ➡️ http://bit.ly/3XZv7gT

we fully agree with this tweet by @ArianeBriegel :

°So proud of @VeroniqueO5
! Her paper on Reversible bacteriophage resistance by shedding the bacterial cell wall is among the top 5 cited articles in Open Biology in 2022!"

also for ornamentation: a few #Streptomyces colonies, please 🙂

#DescribeThatMicrobe Another colorful and interesting contamination on a TSA plate with a celestial feel to it. The red colony was turned blue after sitting on the counter for a few weeks after the first photo. I always take an initial image then wait a few weeks to see how things continue growing. It paid off by turning a lovely blue…..probably an soil bacteria called #streptomyces which gives us that earthy soil smell. #microbiology #Science

@hall_lab
let me know when your re-start bears fruit, please. I'd really like to know more about it. related: when & how do #Streptomyces substrate hyphae decide to branch. talked about this with joost willemse from gilles van wezels lab but they don't have a clear picture yet (despite having great microscopy pictures 😉)
