| Abstract |
Directed evolutionary approach and random mutagenesis were performed on thermotolerant yeast Kluyveromyces marxianus KCTC17694 for isolating a yeast strain producing ethanol from xylose efficiently. The isolated mutant strain, K. marxianus 17694-DH1, showed 290% and 131% improvement in ethanol concentration and ethanol production yield from xylose, respectively, as compared with the parental strain. Sequencing of the KmXYL1 gene of K. marxianus 17694-DH1 revealed substitutions of arginine and tryptophan with lysine and leucine at positions 25 and 202, respectively, as compared to the parental strain. In addition, sequencing of the KmXYL2 gene uncovered a substitution of glutamate with leucine at position 232. When enzymatic assays of xylose reductase (XR) and xylitol dehydrogenase (XDH) from the parental strain and K. marxianus 17694-DH1 were performed, XR activities were not significantly different whereas XDH activities were significantly improved in the mutant strain up to 50 °C of reaction temperatures. RNA-Seq based transcriptome analysis showed that alcohol dehydrogenases and glucose transporters were up-regulated while TCA cycle involved enzymes were down-regulated in K. marxianus 17694-DH1. |

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 24 September 2018.
All research outputs
#20,014,336
of 25,461,852 outputs
Outputs from Bioprocess and Biosystems Engineering
#442
of 604 outputs
Outputs of similar age
#256,963
of 350,933 outputs
Outputs of similar age from Bioprocess and Biosystems Engineering
#1
of 1 outputs
Altmetric has tracked 25,461,852 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 604 research outputs from this source. They receive a mean Attention Score of 3.1. This one is in the 27th percentile – i.e., 27% 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 350,933 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 22nd percentile – i.e., 22% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
