| Abstract |
Foaming problem and cost of substrate limit the commercial application of rhamnolipids, a potential biosurfactant produced by Pseudomonas aeruginosa. We explored the production of rhamnolipids by a semi-solid-state (SSS) fermentation strategy with glycerol as carbon source and rapeseed/wheat bran as matrix, along with the capacity of the produced rhamnolipids to solubilize lead and cadmium in aqueous solution. Structural analysis by MALDI-TOF MS indicated the increased proportion of mono-rhamnolipids from SSS fermentation. E24 results showed the stronger emulsification capacity and reduced water tension of the SSS fermentation product. Rhamnolipids from SSS fermentation can desorb lead/cadmium from contaminated soil effectively and heavy metals in exchangeable and carbonate forms were easily removed. Our findings suggest that SSS fermentation is an alternative for the economical production of rhamnolipids and the product can be used to solubilize heavy metals from soils. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. 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 16 August 2017.
All research outputs
#16,784,715
of 25,461,852 outputs
Outputs from Bioprocess and Biosystems Engineering
#416
of 604 outputs
Outputs of similar age
#198,408
of 327,927 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 32nd percentile – i.e., 32% 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 33rd percentile – i.e., 33% 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 327,927 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 36th percentile – i.e., 36% 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
