A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

About

Although  many clinically and ecologically relevant processes are known to be  performed by biofilm communities composed of strict or facultative anaerobic bacteria, biofilms were often studied in  aerobic conditions.  We use in vitro anaerobic culture systems combined with genetic and genomic approaches to study the molecular basis of biofilm formation by anaerobic commensal and pathogenic bacteria.
