     the purpose of this work was to study the possible use of pretreated biomass of various microalgae and cyanobacteria as substrates for acetone–butanol–ethanol (abe) fermentation by clostridium acetobutylicum cells immobilized into poly(vinyl alcohol) cryogel. to this end, the biochemical composition of photosynthetic microorganisms cultivated under various conditions was studied. the most efficient technique for pretreating microalgal biomass for its subsequent conversion into biofuels appeared to be thermal decomposition at 108 °c. for the first time the maximum productivity of the abe fermentation in terms of hydrogen (8.5 mmol/l medium/day) was obtained using pretreated biomass of nannochloropsis sp. maximum yields of butanol and ethanol were observed with arthrospira platensis biomass used as the substrate. immobilizedclostridium cells were demonstrated to be suitable for multiple reuses (for a minimum of five cycles) in abe fermentation for producing biofuels from pretreated microalgal biomass.
