Leaching of Arsenic from Tailings by Microbially Produced Rhamnolipids

, 2014
The focus of this study was to determine influence of microbial surfactants rhamnolipids on mobilization of heavy metals from the tailings and to estimate the use of rhamnolipids, as washing agents in pretreatment of metal contaminated substrates as ...

Heterologous production of rhamnolipids in Pseudomonas chlororaphis subsp chlororaphis ATCC 9446 based on the endogenous production of N‐acyl‐homoserine lactones

Microbial Biotechnology
Rhamnolipids (RL) are biosurfactants naturally produced by the opportunistic pathogen Pseudomonas aeruginosa. Currently, RL are commercialized for various applications and produced by Pseudomonas putida due to the health risks associated with their large‐

Production of Rhamnolipids by Pseudomonas chlororaphis, a Nonpathogenic Bacterium

, 2020
Rhamnolipids, naturally occurring biosurfactants constructed of rhamnose sugar molecules and ␤-hydroxyalkanoic acids, have a wide range of potential commercial applications. In the course of a survey of 33 different bacterial isolates, we have identified,

Burkholderia thailandensis as a microbial cell factory for the bioconversion of used cooking oil to polyhydroxyalkanoates and rhamnolipids

, 2018
The present work assessed the feasibility of used cooking oil as a low cost carbon source for rhamnolipid biosurfactant production employing the strain Burkholderia thailandensis. According to the results, B.

Enzyme reaction engineering for the conversion of emulsified di-rhamnolipid by free and immobilized Naringinase

, 2009
Process optimization was conducted for the conversion of the aggragate-building substrate di-rhamnolipid to mono-rhamnolipid by Alpha-L-rhamnosidase from Penicillium decumbens and resulting in: (I) selection of optimal reaction conditions for enzyme activity and stability, (II) modeling of the reaction time course assuming mixed aggregates as a second ...
