In this study, two major advantages of microalga Neochloris oleoabundans have been taken into account: purification of the syngas contaminant water (SCW) and providing biomass yield from microalgae growth by using syngas contaminant together with BG11 microalgal growth medium  as a feedstock. 10 kW imbert type downdraft gasifier fueled with wood chips have been used to obtain syngas contaminant . A certain amount of the wood-gas is derived after the biofiltering process and is sent to the Water Algae Photo-Bio-Scrubber System (WAPBS): a series of Drechsel bottles are filled with syngas cleansing water (SCW). Tar and particulate are trapped in the water inside the WAPBS, while part of the syngas contaminant is available for the micro algae to be converted into biomass. At the end of the process char and tar content of the syngas contaminant used by microalgae have been observed and microalgal growth of N. oleoabundans have been monitored during the process of WAPBS.
