High titer heterologous rhamnolipid production [PDF]

AMB Express, 2016
Heterologous mono-rhamnolipid production by Pseudomonas putida KT2440 pSynPro8oT_rhlAB using glucose as the single carbon source was characterized in fed-batch bioreactor cultivations. For the described experiments, a defined mineral salt medium was used, and a two phase glucose feeding profile was applied, which yielded a final rhamnolipid ...

Root uptake of lipophilic zinc-rhamnolipid complexes [PDF]

Journal of Agricultural and Food Chemistry, 2008
This study investigated the formation and plant uptake of lipophilic metal-rhamnolipid complexes. Monorhamnosyl and dirhamnosyl rhamnolipids formed lipophilic complexes with copper (Cu), manganese (Mn), and zinc (Zn). Rhamnolipids significantly increased

Heterologous Rhamnolipid Biosynthesis: Advantages, Challenges, and the Opportunity to Produce Tailor-Made Rhamnolipids [PDF]

Frontiers in Bioengineering and Biotechnology, 2020
The first heterologous expression of genes responsible for the production of rhamnolipids was already implemented in the mid-1990s during the functional identification of the rhlAB operon.

Liposome-encapsulated antibiotics and biosurfactants: an effective strategy to boost biofilm eradication in cooling towers. [PDF]

Microb Cell Fact
An excessive amount of water is needed for cooling towers in oil refineries to cool the machinery. However, water has been observed to favor microbial growth and biofilms significantly.
