Due to the long durations spent inside by many humans, indoor air quality has become a growing concern. Biofiltration has emerged as a potential mechanism to clean indoor air of harmful volatile organic compounds (VOCs), which are typically found at concentrations higher indoors than outdoors. Root-associated microbes are thought to drive the functioning of plant-based biofilters, or biowalls, ...

Smita Raghuvanshi and B. V. Babu Chemical Engineering Department Birla Institute of Technology and Science (BITS) Pilani333031(Rajasthan) India ________________________________________________________________________ Abstract Biofiltration of off gases containing Volatile Organic Compounds (VOCs) is a reliable and cost effective technology for VOCs removal. As most of the enterprises operate in...

Strict environmental restrictions force the aquaculture industry to guarantee optimal water quality for fish production in a sustainable manner. The implementation of anammox (anaerobic ammonium oxidation) in biofilters would result in the conversion of both ammonium and nitrite (both toxic to aquatic animals) into harmless dinitrogen gas. Both marine and freshwater aquaculture systems contain ...

The characterization of polutant-degrading microorganisms from contaminated soils, waste water treatment plants or biofilters for the cleaning of waste gases usually starts with enrichment cultures and ends with the taxonomical and functional characterization of the isolated strains. However, the use of cultivation independent techniques, like cloning and sequencing of marker genes, indicate th...

Biofiltration of industrial carbon disulfide (CS2)-contaminated waste air streams results in the acidification of biofilters and therefore reduced performance, high water use, and increased costs. To address these issues, we isolated 16 extremely acidophilic CS2-converting Acidithiobacillus thiooxidans strains that tolerated up to 6% (vol/vol) sulfuric acid. The ecophysiological properties of f...
