Two novel strains of methanogens were isolated from an estuarine sediment with the capability to utilize quaternary amines. Based on the 16S rRNA analysis, strain B1d shared 99 % sequence identity with Methanolobus vulcani PL-12/M(T) and strain Q3c shared 99 % identity with Methanococcoides sp. PM1 and PM2, but our current isolates display clearly different capabilities of growth on quaternary amines and were isolated based on these capabilities. Strain Q3c was capable of growth on tetramethylammonium and choline, while strain B1d was capable of growth on glycine betaine. Ml. vulcani PL-12/M(T) was incapable of growth on glycine betaine, indicating an obvious distinction between strains B1d and PL-12/M(T). Strain Q3c now represents the only known tetramethylammonium-utilizing methanogen in isolation. Strain B1d is the first quaternary amine-utilizing methanogen from the genus Methanolobus. This study suggests that quaternary amines may serve as ready precursors of biological methane production in marine environments.
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 August 2017.
All research outputs
#7,477,223
of 23,498,099 outputs
Outputs from Archives of Microbiology
#561
of 2,873 outputs
Outputs of similar age
#80,651
of 257,464 outputs
Outputs of similar age from Archives of Microbiology
#4
of 19 outputs
Altmetric has tracked 23,498,099 research outputs across all sources so far. This one has received more attention than most of these and is in the 67th percentile.
So far Altmetric has tracked 2,873 research outputs from this source. They receive a mean Attention Score of 3.7. This one has done well, scoring higher than 79% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 257,464 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 67% of its contemporaries.
We're also able to compare this research output to 19 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 78% of its contemporaries.
