Glucose fermentation with biochar-amended consortium: microbial consortium shift.

The effects of adding biochar rice husk (R), white popinee (WP), bamboo (BB), or coconut (CT) on microbial community in fermentation broths from glucose were investigated. The added biochars acted as biofilm carriers on which 11 sp., 12 sp.

Glucose fermentation with biochar amended consortium: Sequential fermentations.

The aim of this work was to study sequential batch fermentation of glucose with a biological consortium amended with nine different biochars or with an activated carbon. The glucose fermentation was enhanced by carbon amendment, with activated carbon being more effective than biochars as cell carriers and electron conductors between functional species. The volatile fatty acid distributions were shifted in the consumption of the produced H and CO.

Dark fermentation production of volatile fatty acids from glucose with biochar amended biological consortium.

Effects of adding biochars on dark fermentation production of volatile fatty acids (VFAs) from glucose were investigated. Nine biochars were synthesized and applied, together with an activated carbon, as the testing amendment to enhance preferable fermentation. Biochars were porous materials with internal pores and excess surface functional groups, which would lead to enrichment of acetate over butyrate in the VFA production.
