Journal club?

As I’ve been reading through some papers, I’ve been wondering if we should do some kind of journal club? Like a book club, but we decide on a paper to read and discuss. Maybe we could even do it as a YouTube livestream?

I'll be honest, I think I first saw the idea on the [Biotech without Borders]( website, where Danny has been doing live streams on microbiology papers.

@“Gerrit”#p18 Ooh, yes - great idea. Do you have a paper in mind to kick things off?

And do you want to go live straight away, or should we try a couple as MS Teams calls first (I say MS Teams as if we have more than three locations, it becomes the best option for live-streaming due to it's [NDI]( capability)

I’m busy reading Hydrogen Oxidizing Bacteria as Novel Protein Source for Human Consumption: An Overview at the moment. Knowing that I have a deadline for a live stream may help me finish it! :joy:

I would be happy to give MS Teams a try, but Microsoft [discontinued their Linux client in 2022]( and I'm not sure if the PWA the replaced it with supports NDI.

@“Gerrit”#p29 it would only need to be the studio that needed the NDI connection, so the Teams web app should suffice. But if holding the meeting in Teams is going to put people off, it may be better just to have it as a separate event that anyone can join rather than a panel session livestream. We could even record the event and edit down highlights for the Livestream.

It’s a little painful that both of the best video quality options for our studio are Microsoft. We put a huge amount of effort & money into making WebRTC work during lockdown, but couldn’t get a solution that came close to either Zoom or Teams.

@“Gerrit”#p29 And regarding Hydrogen Oxidizing Bacteria as Novel Protein Source for Human Consumption: An Overview, yes I’ve read the abstract and sections 7 & 8 and will definitely be reading the rest. I might also reach out to the authors…

Should we announce Journal Club during Wednesday's livestream - if so, how? I'm hoping to have someone from [OpenFlexure]( join live to help me with my first up-close peak at my first pioreactor culture. If you wanted to announce it, feel free to [use this link to record it]( (ignore any mention of the Residual Chlorine Debate - I’m recycling!) perhaps you could launch an online poll so we could agree a time for the first club meeting..?


And have you seen this paper on electro-cultivation of HOB? How cool is this? I’m way behind on my reading - I stumbled on it looking for an image on HOB and haven’t looked at more than the pictures yet.

I imagine that having the electrode in the bioreactor may help with safety issues as we don’t need to deal with external hydrogen gas transfer, and may even be able to control things to minimise excess hydrogen production. If nothing else it makes for a simpler setup, if we can just pop a couple of electrodes into a Pioreactor… Do you think we could fit this plus air (for CO2) plus nutrient feed and waste lines @CamDavidsonPilon & @Gerrit all in a 20ml bioreactor vial?

@“Martin”#p52 Oh wow, this is uncanny. I wanted to post a message here last night about in situ electrolysis when I saw your concerns about gaseous hydrogen, but I left it because I couldn’t find a link to the paper I read. While I haven’t seen the paper you found, I’ve now found said paper:

[Production of Endotoxin-Free Microbial Biomass for Food Applications by Gas Fermentation of Gram-Positive H2-Oxidizing Bacteria](

It's written by VTT scientists from Finland, maybe working with Solar Foods? They found that in situ water electrolysis inhibits growth of some species but not others.

In March this year I watched a talk by Pam Silver from Harvard on a project called the Bionic Leaf, where they use electrodes connected to solar panels and engineered C Necator to produce plastics/sugar/food/fuels. She also mentioned during her talk that they've used Xanthobacter in the bionic leaf for nitrogen fixation. Here is a paper by their team that's still on my to-read list:

[Water splitting-biosynthetic system with CO2 reduction efficiencies exceeding photosynthesis](

@“Gerrit”#p53 I had a brilliant conversation with Narcís this morning, who also sent me a copy of their latest paper: Electricity-driven microbial protein production: Effect of current density on biomass growth and nitrogen assimilation and also kindly agreed to join us when we discuss his paper(s) at the Journal Club. I’m really looking forward to this…

So, we’re on for 9pm UTC on Monday 4 Dec for the first Journal Club. Please read Electro-cultivation of hydrogen-oxidizing bacteria to accumulate ammonium and carbon dioxide into protein-rich biomass

then join us here at 9pm UTC on Monday.

@“Martin”#p69 Can’t make this Dec 4th one but I will try and make the Dec 18th one. Really interesting paper and I will also read it in my own time.
