  • Lactic acid bacteria dominate urban Bokashi: a participatory, culture-independent pilot study of microbial diversity and functional potential in household-scale food waste fermentation

    FEMS microbes (Oxford University Press, 2026)
    In recent years, concerns over declining biodiversity in urban spaces have increased. Urban Bokashi composting (i.e. microaerobic or anaerobic fermentation of food waste indoors) has been suggested as a possibility to promote microbial diversity in the domestic environment. However, studies on microbial communities in household-scale Bokashi and their potential impacts on health and environment are lacking. Thus, the present pilot study investigated microbial communities in different stages of the Bokashi composting process in collaboration with six Bokashi practitioners by looking into physicochemical characteristics as well as microbial community composition (16S amplicon sequencing, 34 samples) and functional potential (shotgun metagenome sequencing, 11 samples). The collective results indicate that i) microbial communities in Bokashi compost differed between stages, but also between households, ii) microbial communities were dominated by lactic acid bacteria like Lentilactobacillus or Lacticaseibacillus, iii) metabolic pathways for the production of diverse organic acids were detected, iv) application of Bokashi ferment or leachate to soil can supply nutrients and organic acids to promote plant growth but does not substantially affect soil microbial community composition, and v) potentially pathogenic organisms were detected in extremely low abundances. Thus, urban Bokashi is likely not associated with increased health risks and positive impacts are feasible.
  • Bioelectrochemically assisted constructed wetlands for municipal wastewater treatment and the suitability of different biochar materials as system media

    Bioresource technology reports (Elsevier, 2026)
    Microbial electrochemical technology constructed wetlands (METlands) use electroconductive (EC) materials in place of inert substrates such as gravel to enhance pollutant removal. This study evaluated whether EC biochar produced from waste biomass (olive pit, wood pellet, and woodchip) could function as an alternative METland media, an area with limited prior research. Biochars were tested in up-flow columns and compared with coke, a commonly used high-EC medium, and gravel, the typical inert substrate in conventional wetlands. Pollutant removal performance, material properties, biofilm-associated bacterial communities, and gas fluxes were assessed. Biochar and coke generally achieve higher removal of chemical oxygen demand (COD), nitrogen, phosphorus, and selected micropollutants than gravel, indicating that EC biochar can serve as a suitable METland medium. Electroactive bacteria were present at low relative abundance but were highest in biochar systems. Biochar columns also showed higher CO₂, N₂O, and CH₄ fluxes, though these patterns are only indicative due to limited GHG measurements, and further research is needed to clarify greenhouse gas emissions.
