“…Indeed, genome annotations from the Hyphomicrobium genus (www.genome.jp/kegg/), which includes representatives from plant rhizospheres (46), suggest that some species carry genes involved in toluene degradation. Similarly, some Hyphomicrobium strains can degrade formaldehyde, a capacity that has been harnessed by the biosensor industry (47). Other research on biofiltration has identified aromatic/halogenated compound breakdown by relatives of common plant root associates, including Hyphomicrobium, Alcaligenes, Acinetobacter, Burkholderia, Pseudomonas, and Xanthobacter (23).…”

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, converting VOCs into biomass, energy, and carbon dioxide, but little is known about the root microbial communities of such artificially grown plants, how or whether they differ from those of plants grown in soil, and whether any changes in composition are driven by VOCs. In this study, we investigated how bacterial communities on biofilter plant roots change over time and in response to VOC exposure. Through 16S rRNA amplicon sequencing, we compared root bacterial communities from soil-grown plants with those from two biowalls, while also comparing communities from roots exposed to clean versus VOC-laden air in a laboratory biofiltration system. The results showed differences in bacterial communities between soilgrown and biowall-grown plants and between bacterial communities from plant roots exposed to clean air and those from VOCexposed plant roots. Both biowall-grown and VOC-exposed roots harbored enriched levels of bacteria from the genus Hyphomicrobium. Given their known capacities to break down aromatic and halogenated compounds, we hypothesize that these bacteria are important VOC degraders. While different strains of Hyphomicrobium proliferated in the two studied biowalls and our lab experiment, strains were shared across plant species, suggesting that a wide range of ornamental houseplants harbor similar microbes of potential use in living biofilters.

“…Biosensors can be categorized according to their transducer: potentiometric (Ion-Selective Electrodes (ISEs), Ion-Sensitive Field Effect Transistors (ISFETs)), amperometric, conductometric, impediometric, calorimetric, optical and piezoelectric. FA selective biosensors are based on cells (Korpan et al, 1993) or enzymes used as biorecognition elements: either alcohol oxidase (AOX) (Korpan et al, 1997(Korpan et al, , 2000Dzyadevych et al, 2001) or formaldehyde dehydrogenase (FdDH) (Herschkovitz et al, 2000;Kataky et al, 2002, Achmann et al, 2008. A number of sensor approaches for the detection of FA concentration have been published including systems operating in gas (Dennison et al, 1996;Hämmerle et al, 1996;Vianello et al, 1996) and organic phases.…”

“…FA can also be found in the air and enter the one carbon pool for incorporation into the cells constituents (CasanovaSchmitz, 1984). At the moment, three different FdDHes, bacterial NAD + -dependent, yeast NAD + -and GSH-dependent and bacterial dye-linked NAD + and GSH-independent, are widely used for bioanalytical purposes (Ben Ali et al, 2006Winter and Cammann, 1989;Vastarella and Nicastri, 2005;Herschkovitz et al, 2000;Korpan et al, 1993;Gonchar et al, 2002;Korpan et al, 2010;Achmann et al, 2008;Kawamura et al, 2005). Besides FdDH, FA can be easily oxidized by alcohol oxidase (AOX) (EC 1.1.3.13), an enzyme which is responsible in vivo for the first reaction of methanol metabolism in methylotrophic yeast (Klei van der et al, 1990).…”

“…The limit concentration of short-term exposure to formaldehyde is 0.08 ppm for 30 min [38] and 0.016 ppm for long-term exposure [39]. Different types of sensors have been developed in the literature to detect formaldehyde, such as spectro-colorimetric sensors by Suzuki et al, who made a device using organic molecules that change colour when reacting with CH 2 O [40], or amperometric sensors which take benefit from an enzymatic reaction with formaldehyde molecules, which changes the electrical current in the transducer [41]. Other sensors use metal oxides or have very complex testing setups and generally require high working temperatures, for instance, SiO 2 -NiO-based formaldehyde sensors that operate at 300 • C [42].…”

Nanocomposite-based quantum resistive vapour sensors (vQRS) have been developed from the assembly of hybrid copolymers of polyhedral oligomeric silsesquioxane (POSS) and poly(methyl methacrylate) (PMMA) or poly(styrene) (PS) with carbon nanotubes (CNT). The originality of the resulting conducting architecture is expected to be responsible for the ability of the transducer to detect sub-ppm concentrations of ammonia and formaldehyde at room temperature despite the presence of humidity. In particular, the boosting effect of POSS is evidenced in CNT-based nanocomposite vQRS. The additive fabrication by spraying layer-by-layer provides (sLbL) is an effective method to control the reproducibility of the transducers' chemo-resistive responses. In dry atmosphere, the two types of sensors showed a high sensitivity towards both hazardous gases, as they were able to detect 300 ppb of formaldehyde and 500 ppb of ammonia with a sufficiently good signal to noise ratio (SNR > 10). They also exhibited a quick response times less than 5 s for both vapours and, even in the presence of 100 ppm of water, they were able to detect small amounts of gases (1.5 ppm of NH 3 and 9 ppm of CH 2 O). The results suggest promising applications of POSS-based vQRS for air quality or volatolome monitoring.
