Rhamnolipids are a class of biosurfactants which contain rhamnose as the sugar moiety
linked to β-hydroxylated fatty acid chains. Rhamnolipids can be widely applied in many …

Rhamnolipids are glycolipidic biosurfactants produced by various bacterial species. They
were initially found as exoproducts of the opportunistic pathogen Pseudomonas aeruginosa …

Lipopeptides are microbial surface active compounds produced by a wide variety of
bacteria, fungi, and yeast. They are characterized by high structural diversity and have the …

Biosurfactant production by three Bacillus subtilis strains (# 309,# 311 and# 573) isolated
from Brazilian crude oils was optimized based on different carbon and nitrogen sources. The …

Petroleum is the main energy source utilized in the world, but its availability is limited and
the search for new renewable energy sources is of major interest. Biofuels, such as ethanol …

The increasing environmental concern about chemical surfactants triggers attention to
microbial-derived surface-active compounds essentially due to their low toxicity and …

Chemical surfactants are omnipresent in consumer products, but they are the subject of
environmental concerns. For this reason, the complete replacement of petrochemical …

Biosurfactants are amphiphilic molecules that have both hydrophilic and hydrophobic
moieties which partition preferentially at the interfaces such as liquid/liquid, gas/liquid or …

In this study, zein-propylene glycol alginate-rhamnolipid complex particles were prepared
with suitable three-phase contact angles (θ) for stabilizing oil-in-water Pickering high …

This critical review focuses on the origins and preparation of bio-based surfactants, defined
here as non-soap, amphiphilic molecules in which the carbon atoms are derived from …
