Continuous culture of Nitrosomonas eutropha and biomethanol production using whole cell biotransformation

“…Conversion of CH 4 produced from biogas plants can have beneficial impacts on the performance of wastewater treatment. Conversion of biogas to biomethanol can help to enhance the denitrification process by production of biomethanol which can be fed to denitrifiaction reactors as a exogenous C source 14,35 . N. eutropha could utilize CH 4 present in the biogas during biotransformation trials in the bioreactor.…”

“…If MOB are to be used for biomethanol production, the metabolic pathways responsible for further utilization of biomethanol should be selectively inhibited 6,11 . However, there are no known enzymes for biomethanol metabolism present in the genomes of common AOB making it an attractive alternative platform for biomethanol production 12–14 . Biogenic conversion of CH 4 to biomethanol has been demonstrated at the laboratory scale, using mixed and axenic cultures of AOB 14 .…”

Biomethanol is one of the important factors for enhancing the denitrification process at wastewater treatment plants to meet effluent water quality 14 . However, there are several limitations for the production of biomethanol using N. eutropha such as slow growth rate and low transfer efficiencies of CH 4 from gas to liquid phases 1 …”

Improved Performance, Combustion and Emissions of SI Engine Fuelled with Butanol: A Review

“…Alcohols, such as methanol and especially ethanol, have attracted many research groups [25,26]. Methanol production is very limited [27,28], while ethanol, on the other hand, can be manufactured straightforwardly by the fermentation of sugar from a wide variety of sources [29][30][31]. Ethanol is gaining more attention as it has superior octane number, approximately 108, and is thus often mixed with the gasoline to improve its properties quality [32,33].…”
