TL;DR: Rhamnolipids have the highest potential for becoming the next generation of biosurfactants introduced on the market and there is a need to gain a deeper understanding of the regulation of rhamnlipid production on process and cellular level during bioreactor cultivation.

TL;DR: A next-generation rhamnolipid producing strain, as proposed within this review, may be engineered towards reduced formation of byproducts, increased metabolic spectrum, broadened substrate spectrum and controlled regulation for the induction of rhamNolipids synthesis.

TL;DR: Improved H2 production efficiency was achieved at increased solar flux densities and high cell densities which are best suited for microalgae production as light is ideally the limiting factor and the overall improved photon-to-H2 conversion efficiency is suggested.

TL;DR: A comprehensive overview of the knowledge available on actinobacterial surfactants, the chemical structures that have been completely or partly elucidated, as well as the identity of the biosurfactant-producing strains is presented.

TL;DR: The nonpathogenic actinomycetes Tsukamurella spumae and Tsukamureslla pseudospumae are described as producers of extracellular trehalose lipid biosurfactants when grown on sunflower oil or its main component glyceryltrioleate.
