Kessler et al. (Reports, 21 January 2011, p. 312) reported that methane released from the 2010 Deepwater Horizon blowout, approximately 40% of the total hydrocarbon discharge, was consumed quantitatively by methanotrophic bacteria in Gulf of Mexico deep waters over a 4-month period. We find the evidence explicitly linking observed oxygen anomalies to methane consumption ambiguous and extension ...
• End-products of sludge-based AD were used for SCP production the first time. A potential solution to valorize underutilized products generated at WWTPs. Methylomonas dominated in mixed culture. The protein content reached 41% w/w dry weight. Several essential amino acids detected. Single cell (SCP) provides an alternative source partially replace conventional agricultural resources and suppor...
With the recent drop in natural gas prices in the United States, there is heightened interest to use methanotrophic bacteria to produce commercial products such as liquid fuels. This project was recently funded to explore this paradigm. This paper describes a bacterium that grows on methane and produces copious amounts of polyhydroxy butyrate.

It was hypothesized that nutrient removal from waste water could be achieved by using methane oxidizing bacteria (melhan otrophs). Because methane is inexpensive. it can be used as an energy source to encourage bacterial growth to assimilate nitrogen and phos phorus and other trace elements. This initial feasibility study used syn thetic nutrient mixtures and secondary sewage effluent as fe...
Highly enriched methanotrophic communities (> 25 serial transfers) were obtained from acidic ombrotrophic peat bogs from four boreal forest sites. The enrichment strategy involved using media conditions that were associated with the highest rates of methane uptake by the original peat samples, namely, the use of diluted mineral medium of low buffering capacity, moderate incubation temperature (...
We tested the hypothesis that low stable carbon isotope (d13C) values commonly observed for zooplankton in humic lakes are due to their feeding on isotopically light methane-oxidizing microbes, and thus that methanederived carbon is important in the food webs of these lakes. In replicate laboratory cultures, Daphnia longispina, a common crustacean zooplankter in humic lakes, were fed microbial ...
