“…TOC, including the amount of 4-isopropylbenzic acid, were 0 mg, 0.994 mg and 2.007 mg for the strain ZW and the mutant ZW-A cultured in the original and optimized medium, respectively. This suggested that the SO 4 2− greatly influenced the accumulation of 4-isopropylbenzoic acid and other intermediates.…”

“…2,3 As the most cost-effective and environment-friendly technology, biopurification, characterized by the conversion of pollutants into harmless products by microbial metabolism, has been chosen as a suitable technique for the removal of pollutants in most cases. 2,4 One important requirement for applying this technology and achieving success is the acquisition of microorganisms having appropriate metabolic capabilities for specific pollutants. In the past twenty years, many studies on microbial isolations (aerobic or anaerobic) and their biodegradation characteristics to typical compounds (chlorobenzene, toluene, etc.)…”

“…Biofiltration processes are based on the ability of microorganisms to attach to packing media in the form of biofilms (Groenestijn and Kraakman, 2005;Kim et al, 2007;Yang et al, 2011). During the processing exhaust gas, these pollutants are absorbed by the biofilm and converted into carbon dioxide (CO 2 ), water (H 2 O), and biomass without generating undesirable by-products (Devinny et al, 1999;Kennes, 2012). Biotechnology can effectively control low-concentration pollutants (Iranpour et al, 2005).…”

h i g h l i g h t sThe biofiltration generally emit more than 10 4 CFU m À3 bioaerosol. The bioaerosol emitted from the biofiltration is a potential threat to human body. Shear force and dilution affect the concentration of bioaerosol emissions. PCD is promising to control bioaerosols because of few secondary pollutants. a b s t r a c tBioaerosols have widely been a concern due to their potential harm to human health caused by the carrying and spreading of harmful microorganisms. Biofiltration has been generally used as a green and effective technology for processing VOCs. However, bioaerosols can be emitted into the atmosphere as secondary pollutants from the biofiltration process. This review presents an overview of bioaerosol emissions from gas bioreactors. The mechanism of bioaerosols production and the effect of biofiltration on bioaerosol emissions were analyzed. The results showed that the bioaerosol emission concentrations were generally exceeded 10 4 CFU m À3 , which would damage to human health. Biomass, inlet gas velocity, moisture content, temperature, and some other factors have significant influences on bioaerosol emissions. Moreover, as a result of the analysis done herein, different inactivation technologies and microbial immobilization of bioaerosols were proposed and evaluated as a potential solution for reducing bioaerosols emissions. The purpose of this paper is to make more people realize the importance of controlling the emissions of bioaerosols in the biofiltration process and to make the treatment of VOCs by biotechnology more environmentally friendly. Additionally, the present work intends to increase people's awareness in regards to the control of bioaerosols, including microbial fragment present in bioaerosols.

“…Biofilters, biotrickling filters, and bioscrubbers are the major bioreactor designs usually considered in these applications (Kennes, 2012;Li, Wan et al, 2012;Ottengraf, 1987;Wan et al, 2011). Over the last two decades, researchers have focused on developing biological methods for the treatment of gaseous streams containing SO 2 (Buisman et al, 1990;Philip and Deshusses, 2003;Selvaraj et al, 1997;Selvaraj and Sublette, 1995).…”

Sulfide dioxide (SO 2 ) is often released during the combustion processes of fossil fuels. An integrated bioreactor with two sections, namely, a suspended zone (SZ) and immobilized zone (IZ), was applied to treat SO 2 for 6 months. Sampling ports were set in both sections to investigate the performance and microbial characteristics of the integrated bioreactor. SO 2 was effectively removed by the synergistic effect of the SZ and IZ, and more than 85% This work presents a potential biological treatment method for waste gases containing hydrophilic compounds.
