| Abstract |
The effect of chitosan on Saccharomyces cerevisiae (the yeast that carries out alcohol fermentation), Brettanomyces bruxellensis and Brettanomyces intermedius (contaminants of alcohol fermentations), was investigated. The effect of chitosan was tested on each yeast, as well as on mixed cultivations of S. cerevisiae + B. bruxellensis and S. cerevisiae + B. intermedius. Chitosan enhanced the lag period of both strains of Brettanomyces (80 h for B. bruxellensis and 170 h for B. intermedius with 6 and 2 g/l chitosan, respectively). The growth rate of S. cerevisiae was inversely proportional to the chitosan concentration; the former was 50% when 6 g/l polysaccharide was used. Moreover, in mixed cultivations of S. cerevisiae and Brettanomyces strains, it was found that both B. bruxellensis and B. intermedius failed to grow while growth of S. cerevisiae was not affected (using 3 and 6 g/l chitosan, respectively). An interesting collateral result was that the presence of chitosan accelerated the consumption of glucose in the mixed cultivations (60 h instead of 120 h). |

Attention Score in Context
This research output has an Altmetric Attention Score of 9. 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 10 March 2016.
All research outputs
#3,798,287
of 25,371,288 outputs
Outputs from Journal of Industrial Microbiology & Biotechnology
#117
of 1,612 outputs
Outputs of similar age
#10,249
of 147,396 outputs
Outputs of similar age from Journal of Industrial Microbiology & Biotechnology
#3
of 6 outputs
Altmetric has tracked 25,371,288 research outputs across all sources so far. Compared to these this one has done well and is in the 83rd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,612 research outputs from this source. They receive a mean Attention Score of 4.4. This one has done well, scoring higher than 86% 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 147,396 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 90% of its contemporaries.
We're also able to compare this research output to 6 others from the same source and published within six weeks on either side of this one. This one has scored higher than 3 of them.
