“…Biological processes are one of the most commonly accepted explanations for formaldehyde degradation. 43 The widespread occurrence of glutathione-dependent formaldehyde dehydrogenase (GDFADH) in microorganisms suggests that this could be a common agent for biological oxidation of formaldehyde. 44 The fungal diversity in the actual building is high, but some species, such as Cladosporium , Aspergillus and Penicillium , are frequently found.…”

The occurrence of mould and effect of formaldehyde emission on indoor air pollution has been widely reported. However, the potential effect of mould on formaldehyde emissions from building materials has been rarely examined. In this study, the formaldehyde emission from medium-density fibreboards was monitored in three full-scale unoccupied experimental houses for 24 months. Moulds were infested in two out of the three houses. Different indoor formaldehyde concentrations were observed accordingly. Three different stages of variation in concentrations were observed among the houses. In the first stage, when there was no mould growth in any of the houses, indoor formaldehyde concentrations varied in the same way. In the second stage, a large amount of mould was infested in one of the houses, and its formaldehyde concentration was reduced substantially and exhibited a trend opposite to those of the other two houses. In the third stage, 5% of the medium-density fibreboards were covered with mould in another house, and the difference in formaldehyde concentration compared to that in the house without mould growth was increased after that. The different indoor formaldehyde concentrations due to the presence of mould in these houses indicated the inhibitory effect of mould growth on formaldehyde emissions.

“…Various technologies have been developed for formaldehyde removal, such as adsorption, [9,10] low‐temperature plasma purification, [11] microbial degradation, [12] photocatalytic oxidation, [13–15] and thermal catalytic oxidation [16–19] . Among them, thermal catalytic oxidation of HCHO into CO 2 and H 2 O is considered as most promising due to the advantages of high removal efficiency, long‐time effectiveness, energy‐saving, economic feasibility, and lack of secondary pollution [20–22] .…”

Nanocomposites of nickel‐aluminum hydrotalcite (Ni−Al HT) and boehmite (AlOOH) decorated with Pt nanoparticles (NPs) were synthesized and evaluated for catalytic oxidation of formaldehyde at ambient temperature. Experimental results showed that Ni−Al HT modification improved the activity of Pt/AlOOH, and the nanocomposite with Ni/Al molar ratio of 1 : 9 (Pt/Ni1Al9) exhibited remarkable and stable catalytic activity. Characterization results indicated that Pt/Ni1Al9 had a larger specific surface area, higher degree of Pt NPs dispersion, and more surface active sites compared to the nanocomposites with other Ni/Al ratios. The enhanced catalytic activity of Pt/Ni1Al9 was attributed to the generation of more surface active oxygen species from the adsorbed oxygen molecules, which was activated by the electron transfer between Ni−Al HT and Pt/AlOOH, and the suitable interaction and synergistic effect among Ni−Al HT, Pt NPs, and AlOOH. These findings indicate that the nanocomposites of Ni−Al hydrotalcite and boehmite hold significant promises for removal of indoor formaldehyde.

“…Biological control, such as microbial degradation, is the most commonly applied method for treatment of wastewaters containing biodegradable compounds (Bhakta et al 2012;Kanmani et al 2012;Ashraf et al 2011). Many microorganisms have been shown to degrade formaldehyde in the sewage, and bacterial degradability has been the research hotspot on formaldehyde degradation (Di Maiuta et al 2009;Arutchelvan et al 2005;Hidalgo et al 2002). Nevertheless, there is fewer fungal resources that are able to degrade formaldehyde have been reported (Sawada et al 2006).…”

Formaldehyde is widely used in chemical manufacturing industry and classified as a human carcinogen. Discharging wastewater containing formaldehyde without treatment can cause serious risk to the water environment. In this study, a formaldehyde-resistant fungal strain was isolated from sewerage of a furniture factory. Isolate strain was identified based on the morphological and phylogenetic analyses. Formaldehyde-degrading fungus was determined by characterizing the mycelia growth in culture media, formaldehyde-resistant, formaldehydedegrading efficiencies, and specific enzyme activity involved in formaldehyde removal. Isolate strain HUA was identified as a member of Aspergillus sydowii. The strain HUA showed a growth in the presence of formaldehyde up to 2,400 mg l -1 at an optimum temperature of 25°C and optimum pH of 7. The specific activity of formaldehyde dehydrogenase and formate dehydrogenase could reach up to 5.02 and 1.06 U mg -1 , respectively. It indicated that isolated formaldehyde-resistant A. sydowii HUA strain would be potential used for removing formaldehyde from industrial wastewater.
