摘要: Abstract Two outdoor photobioreactors were operated to evaluate the effect of variable ambient temperature on an indigenous microalgae-nitrifying bacteria culture dominated by Chlorella. Four experiments carried out in different seasons, maintaining temperature-controlled PBR at around 25 °C (by either heating or cooling), while non-temperature-controlled was allowed vary with conditions. Temperatures range 15–30 °C had no significant microalgae cultivation performance. However, when rose 30–35 °C viability significantly reduced. Sudden rises triggered AOB growth culture, which worsened performance, especially activity made system ammonium-limited. Microalgae could be recovered after a short peak over 30 °C once dropped, but stopped maintained 28–30 °C for several days.
