Some Pseudomonas sp. are reported for biosurfactant production with glucose as a carbon source, where as other Pseudomonas sp. reports the significant BS production with hydrocarbon. Why?
One of the reasons could be
on account of differential capacity of biosurfacetants to utilise different carbon sources as substrate for their multiplication...
I think this may have to do with 1. the variegated mechanisms through bacteria utilise nutrients, or carbon sources, in their metabolism and expression of secondary metabolites, such as biosurfactants and 2. the environment where the surfactant expressing bacteria were authocthonous to, i.e. bacteria isolated fromk petroleum contaminated soils may prefer petrochemicals or hydrocarbons as carbon sources, and may elaborate biosurfactants at a higher rate when subsisting on that carbon sources.
I also recommend this paper Article Culture Medium Development for Microbial-Derived Surfactants...
I wish it will be useful to you. Thanks
Biosurfactant secretion depends on the nutrient source, nature of food, competing population, presence of other species, environmental condition etc. Uptake of hydrocarbon as food requires an emulsifying agent to increase the surface area of the hydrocarbon as they are mostly hydrophobic and do not easily transport through membranes. Whereas glucose is a very simple and easy food source and does not require complex mechanism during uptake.
