A DICTYOSTELIUM BASED WASTE WATER RECLAMATION SYSTEM

Abstract:

We propose a practical new concept for a bioreactor to remove
microbiota from waste water. It will convert potentially harmful
microorganisms to innocuous cellulosic structures which can then be
biologically degraded further. This process will use no filters or
other expendibles and operate at micro- or partial gravity. It will
provide hygiene and possibly potable water depending on influent
quality. Our concept innovatively exploits the unique biology of
Dictyostelium. While executing its life cycle, Dictyostelium
converts, its food, a range of microbiota, into cellulose and
protoplasm. In liquids, the Dictyostelium ameba stage actively
feeds and divides until its food is exhausted without completing
its life cycle. Culmination occurs only on solid surfaces where it
differentiates into the mature cellulose-containing stage. Since a
reliable waste reclamation method allowing for successful long term
manned missions is an essential component of a regenerative life
support system, the innovation is relevant and important.

In field situations such as in closed habitats as in submarine
environments, remote locations on land (desert environments) and
wherever potable and hygiene water is scarce could be applications
for this concept. If it turns out that yields can be fairly large,
it could replace filters in some biomedical applications.
