Fig 4. Distribution of the frequently occurring Fe-S families of aerobes and HC anaerobes within facultative anaerobes (A) and LC aerotolerant anaerobes (B).
The black part of the column indicates the occurrence of the families of the three groups defined in Fig 2 within facultative anaerobes (A) and LC aerotolerant anaerobes (B). The grey part of the column indicates the absent families. The last columns correspond to Fe-S families unique to facultative anaerobes (A) and LC aerotolerant anaerobes (B), i.e. not mapping to any family in the Venn diagram of Fig 2.
