Other than sophorolipids, common biosurfactants include rhamnolipids which can be produced by some species of Pseudomonas, and Lecithin which can be obtained either from soybean or from egg yolk and is a common food ingredient.

The generic epithet Pseudomonas was coined by Walter Migula in 1894, who did not give an etymology.
The leaves have an antibacterial action and have been shown to be effective against Staphylococcus aureus, Bacillus dysenteriae, Bacillus subtilis, Bacillus typhi, Escherichia coli and Pseudomonas.
Most cultures available contain a research based consortium of Microbial cultures, containing all necessary microorganisms (B. licheniformis, B. thurengensis, P. polymyxa, B. sterothemophilus, Penicillium sp., Aspergillus sp., Flavobacterium, Arthrobacter, Pseudomonas, Streptomyces, Saccaromyces, Triphoderma, etc.).
They remain solid, as very few bacteria are able to decompose agar (the exceptions being those in the following genera: Cytophaga, Flavobacterium, Bacillus, Pseudomonas, and Alcaligenes).
After approximately 24 hours of growth at 28°C in Tryptic Soy Agar medium, Pseudomonas peli colonies are 1–2 mm in diameter, beige to yellow in color and have non-uniform edges while the cells themselves are rod shaped (width near 1μm and length between 2-3 μm) with rounded ends.
Pseudomonas tolaasii is a species of Gram-negative soil bacteria that is the causal agent of bacterial blotch on cultivated mushrooms (Agaricus bisporus).
Gluconic acid is found naturally, and is industrially manufactured by the fermentation of glucose, typically by Aspergillus niger, but also by other fungi, e.g. Penicillium, or by bacteria, e.g. Acetobacter, Pseudomonas and Gluconobacter.
