🧵1/6 The second paper of my PhD is out now! Advanced access article here: https://t.co/Einx6WEP5H I’ll also be presenting these results at the ISME19 in Cape Town this week @MarineMicrobio @MolEcol_MPIMM

Abstract. Heterotrophic microbes are central to organic matter degradation and transformation in marine sediments. Currently, most investigations of benthi

Vagabonds and homebodies: #Bacteria have neatly organized their housing space in the #seafloor: Some enjoy the bustle in the yummy porewater. Others stick to sand grains, living off the leftovers. https://t.co/gEsoNCKEM6 Out now @ISMEJournal

Interested in how sediment bacterial communities are structured and what they’re doing? Drop by my poster today and let’s chat about sediment bacterial niches, and the so-far under appreciated role of porewater (and loosely attached) bacteria in surface sediments 😃 #ISME19

6/6 If you're at ISME19 this week, I will be happy to hear your thoughts and talk about this more at my poster (PS3.15.036) at the marine microbial ecology afternoon poster session on Thursday!

5/6 We propose that cells in the porewater and those loosely attached to grains can easily access food and oxygen through the movement of water in the pore space. Firmly attached cells could be those occupying protected, yet diffusion-limited areas like cracks on the grain.

4/6 We found that the porewater and loosely attached fractions are enriched in taxa that are specialized/primed to respond to fresh inputs of organic matter. The firmly attached fraction had a different community which do not necessarily need oxygen or fresh organic matter

3/6 We fractionated the sediment community into those in the porewater, loosely attached to grains, and firmly attached to grains. We assessed the community composition & activity through sequencing and measuring hydrolysis rates, O2 consumption, and frequency of cell division.

2/6 We wanted to gain higher-resolution info about bacterial communities in sediments and go beyond the bulk. In the water column realm, we have learned so much from fractionating the community into free living and particle attached. So we did something similar in the sediment!

Had a fantastic time at the GRC Marine Microbes last week! Highly recommend this GRC as a great opportunity to meet fellow PhD students, early career scientists, and PIs at the forefront of marine microbiology. Also, the location and scenery were outstanding! 🏔️🐄🧀

We are in Bremen at the It Ma(t)ter(s) conference between @MarineMicrobio and @mpi_marburg! We have had the pleasure to hear an opening keynote by @GretaReintjes, who started this conference in 2017. Looking forward to the 3 days of scientific exchange between the two institutes!

Check out the Ellrott grab in action + some behind the scenes! Thanks for featuring our work on #MethodsMonday @aslo_org! @MarineMicrobio 🌊
💡Happy #MethodsMonday! Today, we're exploring an #ASLO_Methods #openaccess article on the #EllrottGrab. Designed and built by @ChyMoncada et al. from @MarineMicrobio, this innovative sediment sampler was created to collect undisturbed surface sediments. 🔓 https://t.co/EqxZeuqU2u

Sharing our new manuscript in @ISMEJournal led by Dr @TessFHutchinson and @MBiogeochem. By tracking how the carbon in glucose is broken down in samples and isolates, she definitely shows fermentation dominates in sands, anaerobic respiration in muds.
