Effects of Inoculation with Lactic Acid Bacteria on the Preservation of Nannochloropsis gaditana Biomass in Wet Anaerobic Storage and Its Impact on Biomass Quality

Wet anaerobic storage of algal biomass is a promising preservation approach that can ensure continuous supply these feedstocks to biorefineries year-round. An effective solution must minimal dry matter loss and change in biochemical composition during storage. Therefore, the objective this study investigate Nannochloropsis gaditana through wet its impact on quality. Prior storage, algae sample inoculated with two different strains lactic acid bacteria thereafter stored for 30 180 days. Each inoculant limited <10% (dry basis) after duration. Final pH values (4.3–4.8) indicate samples are properly ensiled, achieving acidic conditions necessary preservation. Compositional analysis shows reduction carbohydrate content, relative increase lipid no significant protein fraction. Glucose galactose were most prevalent sugar monomers. The low compositional an means preserving ensuring constant feedstock biorefinery.
