| Outline of Final Research Achievements |
This study aimed to elucidate the PHA accumulation mechanism from wastewater substrates by mixed microbial cultures with high PHA accumulation ability that are constructed from activated sludge by a feast-famine method. Results of this study revealed the followings: (1) Most of activated sludge bacteria are capable of producing PHA, (2) short-chain fatty acids are preferable substrates for PHA production by PHA-accumulating bacteria in activated sludge, and (3) PHA-accumulating bacteria belonging to Rhodocyclales make a great contribution to PHA accumulation by mixed microbial cultures constructed from activated sludge by a feast-famine method.
