Fuel and oil spills during the exploration, refining, distribution of petrochemicals are primarily responsible for accumulation organic pollutants in environment. The reduction contamination caused by hydrocarbons, heavy metals, oily effluents, particulate matter generated industrial activities efficient recovery at great depths an environmentally friendly way pose a challenge, as cleaning processes require direct application surface-active agents, detergents, degreasers, or solvents, often generating other environmental problems due to toxicity these substances. Thus, natural agents is attractive solution. Due their amphipathic structures, microbial surfactants solubilize through formation small aggregates (micelles) that disperse water, with numerous applications petroleum industry. Biosurfactants have proven usefulness solubilizing trapped rock, which prerequisite enhanced (EOR). also important biotechnological anti-corrosion processes, preventing incrustations biofilms on metallic surfaces, used formulations emulsifiers/demulsifiers, facilitate transport pipelines, innovative use can reduce generation from synthetic detergents chemical solvents without sacrificing economic gains Therefore, investments essential. It predicted that, not-too-distant future, will become viable standpoint dominate world market. biosurfactants settings would lead growth sustainability. main goal this paper provide overview diverse remediation, biotechnology, industry scientific literature review.

Biosurfactants are molecules of 21st century. Their application(s) intercedes in daily life living beings. Major limitation the wide applicability biosurfactant(s) is economicity production. To overcome this several strategies can be employed. This review centered on recent technological advancements biosurfactant research. The advancement(s) include use metabolomic and sequence based omics approaches that has become a high-throughput indispensable tool for identification producers. A plethora microorganisms synthesize biosurfactants, along with other value-added products namely ethanol, microbial lipids, polyhydroxyalkanoates been reported. significantly improve economics overall process limitations further dealt by employing metabolic engineering approaches. Tailoring strategy enables modification composition congeners produced improves yield biosurfactant. Bio-based surfactants have shown promising results against combating pollution terrestrial aquatic ecosystems either increasing their bioavailability or aqueous solubility. Owing to ever-increasing market biosurfactant(s), summarized technologically feasible research may enable researchers develop more safer reliable technologies.

A Biosurfactant from Candida bombicola: Its Synthesis, Characterization, and its Application as a Food Emulsions

Foods, Journal Year: 2022, Volume and Issue: 11(4), P. 561 - 561

Published: Feb. 16, 2022

The present study aimed to produce a biosurfactant from Candida yeast cultivated in low-cost medium made of sugar-cane molasses (5%), frying oil waste and corn steep liquor (5%). Initially, the production at flask-scale was investigated then scaled up bioreactors 1.2, 3.0, 50 L simulate real scale. products obtained an excellent reduction surface tensions 70 29 mN·m-1 flask-scale, comparable 33 1.2-L reactor, 31 3-L 30 50-L reactor. Regarding yield, it observed that isolation by liquid-to-liquid extraction aided 221.9 g·L-1 with critical micellar concentration 0.5%. isolated did not exhibit inhibitory effect on germination vegetable seeds presented no significant acute toxicity assays Artemia salina Allium cepa. Among different formulations mayonnaise-like sauces, most stable formula addition 0.5% greatest results were associated guar carboxymethyl cellulose gums. Thus, C. bombicola represents promising alternative as food additive emulsions.
