Accumulation of polyhydroxyalkanoates by Microlunatus phosphovorus under various growth conditions.

Microlunatus phosphovorus is an activated-sludge bacterium with high levels of phosphorus-accumulating activity and phosphate uptake and release activities. Thus, it is an interesting model organism to study biological phosphorus removal. However, there are no studies demonstrating the polyhydroxyalkanoate (PHA) storage capability of M.
