Screening of native microalgae species for carbon fixation at the vicinity of Malaysian coal-fired power plant

Abstract Global warming has become a serious issue nowadays as the trend of CO2 emission is increasing by years. In Malaysia, the electricity and energy sector contributed a significant amount to the nation’s CO2 emission due to fossil fuel use. Many research works have been carried out to mitigate...
