| Abstract |
Taurine, 2-aminoethanesulfonate, is known to function as an antioxidant or membrane stabilizer in eukaryotic cells, but its role in bacteria has been poorly characterized. Biofilm formation of Acinetobacter oleivorans DR1 was significantly reduced by taurine only during alkane degradation, suggesting that taurine affects alkane-induced cell surface. Structurally similar compounds harboring an amine group such as hypotaurine or ethylenediamine have a similar effect, which was not observed with sulfonate-containing chemicals such as ethanesulfonic acid, hexanesulfonic acid. Our biochemical assays and physiological tests demonstrate that taurine reduced cell surface hydrophobicity, which resulted in interruption of the interactions between cells and oily substrate surfaces, such that cells utilized alkanes less effectively. Interestingly, taurine-mediated reduction of quorum sensing (QS) signal production and QS-control sapA gene expression indicated that membrane permeability of quorum signals was also interfered by taurine. Composition and biomass of extracellular polymeric saccharides were changed in taurine-amended conditions. Taken together, our data provide evidence that amine-containing taurine can inhibit biofilm formation of DR1 cells during alkane degradation by (i) changing cell surface charge and (ii) reducing membrane hydrophobicity and QS sensing. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 11 August 2017.
All research outputs
#15,465,171
of 22,981,247 outputs
Outputs from Microbial Ecology
#1,475
of 2,063 outputs
Outputs of similar age
#199,138
of 317,090 outputs
Outputs of similar age from Microbial Ecology
#42
of 51 outputs
Altmetric has tracked 22,981,247 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,063 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.4. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
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 317,090 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 51 others from the same source and published within six weeks on either side of this one. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
