Biosurfactants are biodegradable, non-toxic, and environmentally beneficial substances that are produced by microorganisms. Due to their chemical characteristics and stability in various environmental circumstances, biosurfactants are low-molecular-weight, surface-active molecules of great industrial importance. The choice of the producer microbe, kind of substrate, and purification technique determine the chemistry of a biosurfactant and its production cost. Biosurfactants' amphiphilic nature has proven to be quite advantageous, allowing them to disperse onto two immiscible surfaces while lowering the interfacial surface tension and boosting the solubility of hydrophobic substances. Microbial surfactants are replacing their chemical counterparts in research and usage because of their low or non-toxic nature, durability at higher temperatures, capacity to endure wide range of pH variations and degrade naturally. Biosurfactants are often used as anti-adhesives, emulsifying/de-emulsifying agents, spreading agents, foaming agents, and detergents that have significance in a range of industries such as agriculture, biomedical, bioremediation, the manufacturing industry, and cosmetic. Recent advancements in biosurfactant production have enhanced its usefulness and research interest in a circular economy framework. These advancements include the use of alternative substrates, including various forms of organic waste and solid-state fermentation. Here, we attempted a comprehensive review of biosurfactants, their usage, latest research, limitations, and future aspects.

Bioremediation, involving the strategic use of microorganisms, has proven to be a cost-effective alternative for restoring areas impacted by persistent contaminants such as polycyclic aromatic hydrocarbons (PAHs). In this context, the aim of this study was to explore hydrocarbon-degrading microbial consortia by prospecting native species from soils contaminated with blends of diesel and biodiesel (20% biodiesel/80% diesel). After enrichment in a minimal medium containing diesel oil as the sole carbon source and based on 16S rRNA, Calmodulin and β-tubulin gene sequencing, seven fungi and 12 bacteria were identified.

Optimizing biosurfactant (BS) production is key for sustainable industrial applications. This study investigated BS synthesis by using licuri oil, a renewable carbon source rich in medium-chain fatty acids. Process optimization was conducted via central composite design (CCD), adjusting concentrations of licuri oil, glucose, NHNO, and yeast extract.

Introduction: Burkholderia thailandensis E264 is a non-pathogenic soil bacterium that produces rhamnolipids (RLs), which are utilised in various fields. Although studies have illustrated changes in RLs congeners in response to environmental factors, studies on the influence of temperature on the RLs congeners produced by B. thailandensis E264 are scarce.
