Environment unfriendly nature of chemical surfactants and pollution the environment with heavy metals, especially from industries have become great challenges worldwide, hence need for an urgent solution. This study aimed to search novel strains exhibiting multiple industrial applications heavy-metal tolerance, siderophore biosurfactant capabilities. Soil samples were collected metal dumpsites farmland soils. Isolation, enrichment characterization bacteria carried out using biochemical molecular techniques. Bacterial isolates evaluated metals tolerance by agar-well diffusion smear methods. Siderophore test was iron (III) chloride assay employed in synthesis solvent extraction method. Results showed that prominent genus are Pseudomonas, Proteus, Staphylococcus Micrococcus species. Resistance observed be higher at lower concentrations (100 mg/L) reduced (200–600 mg/L). Six tolerated Ni 600 mg/L five bacterial resisted Pb Zn while other displayed different inhibition zones. The evaluation siderophores revealed only 5 positive. Among positive producers, Burkholderia cepacia strain HB21 gave highest biosurfactants yield (1.87 g/L 0.96 g/L) least 0.74 0.38 produced Achromobacter xylosoxidans 207-4B without agitation.

Surfactants are a group of amphiphilic molecules (i.e., having both hydrophobic and hydrophilic domains) that vital part nearly every contemporary industrial process such as in agriculture, medicine, personal care, food, petroleum. In general surfactants can be derived from (i) petroleum-based sources or (ii) microbial/plant origins. Petroleum-based obvious results petroleum products, which lead to pollution thus pose severe problems the environment leading various ecological damages. Thus, newer techniques have been suggested for deriving surfactant maintaining environmental sustainability. Biosurfactants microbial plant origins offer much added advantages high biodegradability, lesser toxicity, ease raw material availability, easy applicability. they also termed "green surfactants". this regard, review focused on biosurfactants over synthetic produced products along with their potential applications different industries. We provided market aspects future directions considered selections biosurfactants. This would open up new avenues research by overcoming existing bottlenecks field.

Surfactants, a group of amphiphilic molecules (i.e. with hydrophobic(water insoluble) as well hydrophilic(water soluble) properties) can modulate interfacial tension. Currently, the majority surfactants depend on petrochemical feedstocks (such oil and gas). However, deployment these produces high toxicity also has poor biodegradability which cause more environmental issues. To address concerns, current research is moving toward natural resources to produce sustainable surfactants. Among available resources, Cashew Nut Shell Liquid (CNSL) preferred choice for industrial scenarios meet their goals sustainability. CNSL an extracted from non-edible cashew nut shells, doesn't affect food supply chain. The unique structural properties diverse range use cases are key developing eco-friendly that replace petro-based Against this backdrop, article discusses various state-of-the-art developments in cardanol-based such anionic, cationic, non-ionic, zwitterionic. In addition this, efficiency characteristics analyzed compared those synthetic (petro-based). Furthermore, present paper focuses market aspects different applications industries. Finally, describes future perspectives including Artificial Intelligence technology which, late, having huge impact society.

Microbial surface-active agents, such as rhamnolipids, represent an attractive substitute for synthetic surfactants. However, current production bioprocesses are generally inefficient. Adaptive laboratory evolution strategies could offer a promising avenue to improve secondary metabolites production. In the bacterium Burkholderia thailandensis, social behaviour called swarming motility relies on biosynthesis of rhamnolipids. Since experimental requires lower agar concentrations, we hypothesized that augmenting concentration would constrain cells produce more Consecutive rounds B. thailandensis cultivation media performed with increasing concentrations enhanced rhamnolipid by evolved populations, correlation between and concentrations. Whole-genome sequencing superior producing evoluants revealed inactivating mutations in qsmR, which codes transcriptional regulator not known influence Results indicate QsmR represses biosynthetic genes transcription. The developed directed strategy be used biosurfactant yields other bacteria.
