The aerobic biodegradation of high concentrations of 1-propanol and 2-propanol (IPA) by a mixed microbial consortium was investigated. Solvent concentrations were one order of magnitude greater than any previously reported in the literature. The consortium utilized these solvents as their sole carbon source to a maximum cell density of 2.4 x 10(9) cells(More)
The effectiveness of ultrasonication as a pre-treatment method for the psychrophilic anaerobic treatment of aquaculture effluents was assessed using a 4 l solids digester. Ultrasonication of aquaculture wastewater was found to enhance the removal of chemical oxygen demand by anaerobic digestion by almost 10%. There was also a concurrent increase in total(More)
Pot ale from a pilot-scale malt whisky distillery was treated using a mesophilic upflow anaerobic sludge blanket (UASB) digester. Stable operation was observed at organic loading rates (OLRs) of 5.46 kg COD/m3 day or less when the pot ale was diluted with tap water. Digester failure occurred when undiluted pot ale was used, even though OLR was less than 5(More)
We consider operational-level training to be targeted at decision makers; increasing the cognitive readiness of commanders, directors, or staff members in a military or civil organization. Operational-level training is very different from tactical training. Time, space, and forces may be very realistic or highly abstracted or aggregated, depending on the(More)
The aerobic biological oxidation of 2-propanol (isopropyl alcohol, IPA) at extremely high concentrations in air by an enriched solvent-tolerant microbial consortium operating at ambient temperature was evaluated for six months. Solvent-tolerant microbial cells were immobilised onto porous glass pall rings and fed with either IPA or its metabolic product(More)
