Culturing the Unculturable

Culturing bacteria is't always this easy.

Culturing bacteria is’t always this easy.

It is estimated that all the bacterial species so far described represent only a tiny fraction of the total. The rest remain unknown to science because they are “unculturable” in standard (or known) laboratory media. Given that many antibiotics were first isolated from environmental bacteria, it seems likely that these as yet unknown organisms could also be a rich source of potential new drug candidates. The desperate need for new strategies to combat multi-drug resistant infections gives impetus to studies investigating how we can culture some of these “unculturable” bacteria and uncover their potential as a source of much-needed new treatments.  Continue reading
