Biomass accumulation and control strategies in gas biofiltration

Influence of phosphorus availability on the community structure and physiology of cultured biofilms

“…Microbial community composition and succession are fundamental determinants of ecosystem functioning (Naeem et al, 1994), which are controlled by a variety of physicochemical and biological factors (Besemer et al, 2007;Yang et al, 2010). The development of biofilms begins with the attachment of microorganisms to the surface of a support substratum naturally or artificially (Cohen, 2001).…”

“…The development of biofilms begins with the attachment of microorganisms to the surface of a support substratum naturally or artificially (Cohen, 2001). The formation process mainly includes four steps: initial contact between microorganisms or attachment of a microorganism on a solid surface due to physical movement, stable and multicellular contact due to attractive forces, microbial forces to make microorganisms mature, and formation of the three-dimensional structure of biofilms due to hydrodynamic shear forces (Liu and Tay, 2002;Yang et al, 2010).…”

Analytical Expression of Concentration Profiles of Methanol and Pinene in Air Stream and Bio-Film Phase

“…Recently Li et al [3] as well as other research groups [4][5][6][7][8][9][10] have discussed that emission of VOCs into the atmosphere. Currently, biological control processes have become an established technology for air pollution control.…”

Volatile Organic Compounds Removal Methods: A Review

“…The microorganisms that most effectively degrade VOC compounds in biofilters are mesothermic and their optimum activity temperatures are between 30 and 40°C (Clark et al, 2004). In fact, the proper temperature increases the rate of biofilm development and biomass accumulation (Yang et al, 2010). Deeb and Alvarez-Cohen (1999) indicated that in the optimum range of operating temperature, the degradation performance on biofilter can increase 2-fold by 10°C increase in temperature.…”
