doi.org/10.1038/s43247… We clone ANME-1 Mcr to reverse methanogenesis and convert the greenhouse gases CH4 & CO2 into ethanol. We also provide additional evidence that native, methanogenic Mcr is capable of operating in reverse to capture CH4 & CO2 as we found in 2016.

Along with Fe+3 & acetate, Ferry and Yan also use our ANME-1 methane-activated promoter from 2016, but unlike our current 2026 study, they clone two E's (Adh & Fnr) to get ethanol whereas we used the native E's of the host to go from acetate to ethanol.

Add'l proof methanogenesis is reversed for growth by M. acetivorans using our 2016 discovery (DOI 10.1186/s12934-015-0397-z) the terminal e-acceptor Fe+3 must be used & that CH4 is converted to acetate. We also made ethanol by cloning ANME-1 Mcr (doi 10.1038/s43247-026-03601-0).

Ser reported here to increase chemotaxis during resuscitation but we also previously reported that Ala increases chemotaxis during persister resuscitation (2020, doi 10.1016/j.isci.2019.100792).

doi.org/10.64898/2026.… Additional evidence different amino acids influence persister resuscitation; here Ser important. We previously tested all 20 aa's and found Ala most important in 2020 (not cited, doi 10.1016/j.isci.2019.100792) and deduced mechanism.

Add'l evidence that cells in growth arrest (here stationary phase, 12 hr) recover by reviving ribosomes, as shown in 2018 for persister cells using single-cell studies (not cited) and further elaborated in 2020 (doi 10.1016/j.isci.2019.100792, not cited).

We poked E. coli while it was “taking a nap” and… turns out it’s REALLY good at hitting snooze and bouncing back 😴➡️⚡ #CeitecMasarykUniversity #Ribosome #RNA #CryoEM Our new paper in Nat. Commun. dives into how bacteria recover from growth arrest. nature.com/articles/s4146…

"...the ability of biofilms to thwart highly corrosive anaerobic microbes is untested" is patently false. Biocorrosion from same SRB accomplished by the 1st engr'd biofilm for any application, which secreted anti-SRB peptides in 1999.

@EgillRichard Authors here define Abi by citing ref 21 (Sorek, Ann Rev Virol, 2020, "Abortive infection: bacterial SUICIDE...") which defines Abi solely as death. So authors define Abi as death and provide no evidence of it. We should stop using the term Abi & stop redefining it to suit needs.

@crypticprophage Genuine question: why do you consider cell death necessary for abortive infection? Wouldn’t any system that drives the host into dormancy (for instance) upon phage infection also qualify as abortive, by definition?

Drinking the Kool-Aid: You indicate that ToxIN works by "an abortive infection mechanism" yet Fineran et al. themselves originally published in 2009 that there is no Abi as there was no cell lysis, even with pBAD overexpression (pnas.org/doi/10.1073/pn…).

Very excited to share our new paper! Homing endonuclease SegB drives segmental amplification of anti-defense loci, enabling phages to escape multiple bacterial defense systems. nature.com/articles/s4146… Big thanks to Kotaro Chihara and to the Vasili lab.

biorxiv.org/content/10.648… Let's put an end to this trend in phage micro: Calling these bacteria dormant is absurd. Replace with better term, "non-dividing". Takes E. coli 2 wks after starving to become dormant (doi:10.1111/1462-2920.14075). So RNA phages not removed by persisters.
