Collaborating Organization: JISEM

¡Hola! JISEM (Grupo de Jóvenes Investigadores de la Sociedad Española de Microbiología) is the Group of Early Career Scientists of the Spanish Society for Microbiology (SEM). It was launched in 2013 by a small group of PhD students with the goal of enhancing and promoting the activities of the Early Career Scientists within SEM. Since then, it has gained popularity within the Society thanks to its diverse activities, which include:

  • Being represented in different SEM Boards of Trustees
  • Participating in General SEM Congress and biennial meetings of the Teaching & Dissemination SEM Group, organising sessions and round tables on diverse topics
  • Publishing a dedicated section, “MicroJoven”, in SEM’s monthly newsletter “NoticiaSEM” ( These publications include interviews, information on calls and summaries of conferences or courses, among others
  • Preparing interviews to senior Spanish researchers from Spain, which can be followed in the YouTube channel of JISEM
  • Taking part in the selection process and organization of the Introductory Course to Microbiology Research, a competitive program organized every summer by SEM for final year undergraduate students
  • Engaging with the newcomers to the Society and participating in the administration related to their enrollment
  • Elaborating a catalogue of all the Master’s degrees related to Microbiology in Spanish Universities
  • Publishing job offers, grants and relevant articles in their social networks
  • Collaborating with FEMS Opportunity Board in the dissemination of job offers

JISEM is always open to enthusiastic Early Career Scientists aiming to collaborate. You can do so by contacting them by email ( or through their Facebook profile (

Anaerobic Biological Dehalogenation

FEMS Microbiology Ecology is proud to present this latest thematic issue on Anaerobic Biological Dehalogenation. Knowledge on anaerobic microbial dehalogenation has advanced significantly since its first discovery. Understanding of the biochemistry, physiology and ecology of organohalide-respiring bacteria (OHRB) has allowed development of bioremediation technologies for clean-up of contaminated sites. At the same time, a fundamental understanding of the processes, enzymes and organisms involved has allowed to discover new exciting features in biochemistry and microbiology. OHRB are either members of novel bacterial genera or already known ones with other metabolic features indicating the importance of horizontal gene transfer in this anaerobic respiration process. Reductive dehalogenases, thus far discovered, are all corrinoid-containing enzymes revealing unexpected biochemical features of this cofactor normally known to be involved in alkyl-transfer reactions. This special thematic issue shows nicely that there remains still a lot to be discovered regarding anaerobic biological dehalogenation.
