Microbial Ecology of Biofiltration Units Used for the Desulfurization of Biogas
ChemEngineering, 2019 Bacterial communities’ composition, activity and robustness determines the effectiveness of biofiltration units for the desulfurization of biogas. It is therefore important to get a better understanding of the bacterial communities that coexist in ...

Characterization of Compost Biofiltration Media [PDF]
Journal of the Air & Waste Management Association, 1999 The effect of compost quality on performance of biofiltration media was investigated. Three types of compost media were characterized in terms of their key properties, including pH, total organic carbon (TOC) and nitrogen, moisture content, oxygen uptake rates and heterotrophic and fungal plate counts.

Non-conventional gas phase remediation of volatile halogenated compounds by dehydrated bacteria [PDF]
, 2009 Traditional biological removal processes are limited by the low solubility of halogenated compounds in aqueous media. A new technology appears very suitable for the remediation of these volatile organic compounds (VOCs). Solid/gas bio-catalysis applied

Substrate Pre-loading Influences Initial Colonization of GAC Biofilter Biofilms
Frontiers in Microbiology, 2021 Microbial community composition and stability affect pollutant removal for biological/granular activated carbon (BAC/GAC) processes. Here, we pre-loaded the organic carbon substrates sucrose, lactose, and Lysogeny Broth (LB) medium onto new GAC prior to ...
