This paper systematically summarizes the research progress of which mixed bacteria produce PHA using substrate from organic wastewater. Generally speaking

mixed bacteria can produce PHA by two ways

AN/AE technology and ADF technology. Domestic researches emphasized the operating conditions in the reactor including the domestication and accumulation. Besides

the researchers extracted the microorganism producing PHA. Foreign researches emphasized the identification of different kinds of microorganism for keeping PHA. Whats more

they studied the influence that different substrates pose to PHA yield and composition and looked for more effective substrate from organic wastewater. Thanks to some technical breakthrough

PHA producing pattern can apply to industrial production. According to the current producing methods

this paper proposes that more reliable microorganism with high PHA storage should be identified and researches should go deep into the role of specific bacteria. Meanwhile

nutrition from the substrate needs to be balanced. Then it should optimize the operating conditions so as to achieve PHA production maximization.
