Biomass and lipid content of Scenedesmus acutus UD01 cultured in wastewater effluent

SORRACHAT THIAMDAO, Thanitsara Inthasotti

Abstract


The cultivation of microalgae as an alternative energy source has turned become increasingly popular in various  parts of  the  world. However,  the high cost of the media used in the culturing process has directly affected the  manufacturing  cost.  In  this  study,  we have  aimed  to  culture  Scenedesmus acutus UD01  in  the effluent acquired from the  biogas  system  of  a piggery  farm (BGF),  the wastewater of a sugar  factory (SF),  and  modified  JM(MJM).  After  7  days  of  cultivation  under  white  fluorescence  at  room temperature,  the  highest  growth  rate  was  found  in  BGF  and  the  second highest  was recorded in  MJM.  In the  study on the  lipid contents,  the  results  revealed  that  20.09±0.18%  was  obtained  from  S. acutus UD01 cultured  in  SF, while 17.72±1.05% was recorded  in  BGF.              In considering the lipid composition and the process of culturing conducted in the high-cost media, there is a common desire to find an achievable  economic procedure  for  algal  biofuel  production.
