Hey #streptomyces #natprod fans:
1. What is your favourite agar for growing really thick and dense aerial mycelial lawns?
2. How many spores would you inoculate on one 🧫 for thick and dense lawns?

A colleague received proofs of an accepted manuscript, and the "proofing process" clearly involved running the text through ChatGPT. Their voice has been erased, and errors introduced. This is from a supposedly reputable publisher. Anyone else been put through this particular form of hell? #MicroSky

Safety and nutritional claims for raw milk Robert F Kennedy Jr. famously advocates drinking raw milk and promotes its benefits. But how safe is unpasteurised milk? Nicola Holden and Gil Domingue, who sit on Applied Microbiology International's Food Security Scientific Advisory Group, take a deep dive into the science.

Lots of integrative plasmids are linear. Streptomyces Ecoli shuttle plasmids (circular, often low cooy) allow cloning in Ecoli before moving into Streptomyces

The Sequence of a 1.8-Mb Bacterial Linear Plasmid Reveals a Rich Evolutionary Reservoir of Secondary Metabolic Pathways Abstract. Plasmids are mobile genetic elements that play a key role in the evolution of bacteria by mediating genome plasticity and lateral transfer of use

Some Streptomyces plasmids can be huge eg pSCL4 is 1.8Mb!

Streptomyces is not suitable for chemical or electro-transformation methods

Yeah, integrating plasmids can be quite big indeed. If they contain a Tra element than they can be conjugated. This sometimes needs Ecoli strain changeover if host has a methylated DNA restriction system. Plasmids without conjugative element can be moved into Streptomyces via protoplasting

Predatory conference check Q:
Is the Global Food & Agri Summit 2026 in the Netherlands a predatory conference or is it legit?

Could be integrating plasmids? Streptomyces uses this a lot

A new bench at JIC in memory of Helen Kieser. She moved to Norwich with David Hopwood in the 1960s and was instrumental in establishing the Streptomyces group and Molecular Microbiology @johninnescentre.bsky.social. Hard to overstate her importance to the #streptomyces field and community.
