The present work involved screening of two thermophilic bacterial cultures N2 - Bacillus vietnamensis and N3 - Bacillus stearothermophilus for production of ethanol as a result of CO₂ sequestration. The selected bacterial strains were initially screened by providing CO₂ gas and later by providing flue gases which are given out due to combustion of coal in industries. Confirmatory analysis of ethanol production done by GC revealed the presence of higher levels of ethanol production when flue gases were directly bubbled in the thermophile containing media. The thermophiles were initially tested for ethanol production at higher temperatures since the industrial flue gases are released at a very high temperature. The study thus establishes the production of ethanol by both the thermophiles bacterial cultures: Bacillus vietnamensis and Bacillus stearothermophilus.
