Title: Extracellular electron transfer in lactic acid bacteria: squeezing fermentation using electrodes as redox sink
Abstract: The strategy that microorganisms use to extract energy dictates their environmental niche and their interactions with other organisms. Recently, we identified a widespread electron transfer pathway in lactic acid bacteria that allows these microorganisms to reduce extracellular electron acceptors. These species play a major, beneficial role in food fermentation and maintenance of a healthy gut microbiome. The presence of this extracellular electron transfer pathway in lactic acid bacteria was extremely surprising because they are believed to have abandoned electron transfer chains and conserve energy almost exclusively via fermentation. Our research now shows that lactic acid bacteria induce extracellular electron transfer genes and use an anode as electron acceptor to conserve energy and accelerate fermentation under laboratory conditions. Thus, the use of extracellular electron transfer could give lactic acid bacteria a fitness advantage in outcompeting other microorganisms in an ecological context. Additionally, we have investigated whether this metabolism could provide a biotechnological application by changing the flavor and texture of fermented foods.
We are pleased to announce that the North American Meeting of the International Society for Microbial Electrochemistry and Technology (NA-ISMET) will be hosted by the University of Southern California in Los Angeles, California on November 17-19, 2021. The meeting is supported by the United States Department of Energy, Air Force Office of Scientific Research, Army Research Office, Office of Naval Research, and ISMET members. Thanks to the generosity of our sponsors, we anticipate that registration fees will be kept to a minimum, particularly for students and other junior scientists who are ISMET members.
An informational flyer is attached. Abstracts are due July 15, 2021. Please visit the meeting website at naismet2021.usc.edu (the website will be updated with more details in the coming weeks). Please contact email@example.com with any questions.
WISMET will serve as a networking and mentoring collective to support female researchers in microbial electrochemistry and electromicrobiology. For more information on the WISMET seminars, or to become part of the list, head over to the WISMET seminar community page!
The first talk will be on the 14th May 2021 at 2 pm (CEST), where Ezgi Ogun will bring a seminar titled “Utilization of bioelectrochemical mechanisms in environmental engineering applications: treatment and remediation examples.”
We are looking back to our first VIRTUAL ISMET conference, which took place October 7th-9th. Despite all current restrictions in getting together, the ISMET community enjoyed an inspiring exchange of new research outcomes and ideas during this meeting of around 300 scientists with great talks and poster presentations.
We thank our organizers Catarina Paquete, Fernanda Jimenéz-Otero and Lucinda Doyle for taking on this challenge and managing a conference with around 18 time zones.
For the next year, we nevertheless hope to continue our in-person meetings at our regional conferences.
The ISMET community warmly congratulates Dario Shaw for obtaining the 2020 ISMET Discovery Award for his work on an electro-annamox process (Nature Communications 2020) and Xi Chen for receiving the 2020 ISMET Innovation Award for her work on spontaneous hydrogen evolution in BES (Energy and Environmental Science 2020).
Dario is a PhD student in the group of Pascal Saikaly at the Water Desalination and Reuse Center, King Abdullah University of Science and Technology (KAUST) in Saudi Arabia and Xi Chen is Postdoc in Jason Ren’s lab at Princeton University.
The 1st ISMET Virtual meeting will gather researchers and industry affiliates to present and discuss the latest advances in the Microbial Electrochemistry and Technology field.
This three-day meeting will have three keynote talks with outstanding researchers from the field, and several short presentations that covers different topics, including fundamental research on extracellular electron transfer processes, design of bioelectrochemical systems and electrode materials, as well as mode of operating of these systems. It will also accounts for two poster sessions where the ISMET community will have the opportunity to present the latest discoveries of the Microbial Electrochemistry and Technology field. The Innovation and Discovery award from the ISMET will also be announced.
Join us in the 1st Virtual Meeting from the ISMET community. This meeting will be free for ISMET members.
Nomination for the ISMET Awards is open until August 30th 2020

Statement that the nominee and nominator are members of ISMET in good standing.
For Discovery Award: An attachment with the publication for which the nominee is being nominated.
For Innovation Award: Paper or relevant documentation describing the breakthrough technological innovation.
We invite you to participate in the 1st Virtual ISMET Meeting. It will take place from 7th to 9th October 2020, and will reunite scientists from all the word to discuss the recent discoveries on microbial electrochemical technologies.
In this three-day meeting, there will be short presentations covering different topics of this field, including fundamental research on extracellular electron transfer processes, design of bioelectrochemical systems and electrode materials, as well as mode of operating of these systems, and two poster sessions.
Given the current situation due to the COVID-19, and to guarantee that the ISMET community stays in touch with the community, we invite you to participate in this Virtual Meeting. No registration fee is required, but the payment of the ISMET membership is mandatory.
In order to track the number of participants, and to certificate your ISMET membership you have to register in this event.
In response to the pandemic of the novel coronavirus (2019-nCoV) and in accordance with the relevant national regulations for the control of 2019-nCoV, the Board of Directors of the International Society of Microbial Electrochemistry and Technology in agreement with the local organizers of the 2020 Regional ISMET meetings has decided the following:
1. The 5th AP-ISMET conference hosted by the Harbin Institute of Technology (China) will be postponed to May 2021 and the 5th EU-ISMET hosted by the University of Girona (Spain) will be postponed to spring/ summer 2021 with the exact dates being determined. The exact dates to be determined and the topics and activities will remain unchanged.
2. For the participants of the AP-ISMET and the EU-ISMET who have completed registration and payment, all the conference activities registered for participation will be valid at the time of the conference and will continue to be implemented; possible reimbursement measures will be determined.
