Population growth and the need for increased agricultural productivity pose a global problem. Therefore, development of green compounds to ensure sustainability is an urgent necessity. Surfactant hold significant commercial importance due their diverse industrial uses. However, synthetic origin these agents limits application toxicity. As result, extensive research has focused on production microbial-originated surfactants, known as biosurfactants, over past fifteen years. These biomolecules not only offer alternative agriculture but also exhibit reduced toxicity excellent stability under specific environmental conditions. Biosurfactants can lower surface tension more effectively than surfactants. With properties such detergency foam formation, biosurfactants are suitable various applications, particularly in pesticide agrochemical formulations. They function biopesticides manage pests, pathogens, phytopathogenic fungi, weeds antimicrobial activity. Moreover, plants benefit from biosurfactant molecules microorganisms nutrients. aid efficiently distribution micronutrients metals soil. stimulate plant immunity utilized soil hydrophilization proper moisture levels uniform fertilizer distribution. This review aims provide valuable insights into role adjuvants, fostering sustainable formulations replace chemical surfactants used pesticides.

The Physicochemical and Functional Properties of Biosurfactants: A Review

Molecules, Год журнала: 2024, Номер 29(11), С. 2544 - 2544

Опубликована: Май 28, 2024

Surfactants, also known as surface-active agents, have emerged an important class of compounds with a wide range applications. However, the use chemical-derived surfactants must be restricted due to their potential adverse impact on ecosystem and health human other living organisms. In past few years, there has been growing inclination towards natural-derived alternatives, particularly microbial surfactants, substitutes for synthetic or chemical-based counterparts. Microbial biosurfactants are abundantly found in bacterial species, predominantly Bacillus spp. Pseudomonas The chemical structures involve complexation lipids carbohydrates (glycolipoproteins glycolipids), peptides (lipopeptides), phosphates (phospholipids). Lipopeptides, particular, subject extensive research versatile properties, including emulsifying, antimicrobial, anticancer, anti-inflammatory properties. This review provides update progress classification surfactants. Furthermore, it explores various functionalities, along advantages over Finally, applications these many industries insights into future directions discussed.

The rapid emergence of multidrug-resistant pathogens worldwide has raised concerns regarding the effectiveness conventional antibiotics. This can be observed in ESKAPE pathogens, among others, whose multiple resistance mechanisms have led to a reduction effective treatment options. Innovative strategies aimed at mitigating incidence antibiotic-resistant encompass potential use biosurfactants. These surface-active agents comprise group unique amphiphilic molecules microbial origin that are capable interacting with lipidic components microorganisms. Biosurfactant interactions different surfaces affect their hydrophobic properties and as result, ability alter microorganisms’ adhesion abilities consequent biofilm formation. Unlike synthetic surfactants, biosurfactants present low toxicity high biodegradability remain stable under temperature pH extremes, making them potentially suitable for targeted medical pharmaceutical applications. review discusses development biomedical therapeutic uses antimicrobial antibiofilm agents, addition considering synergistic effect combination Furthermore, anti-cancer anti-viral relation COVID-19 is also discussed.

Biosurfactants as Multifunctional Remediation Agents of Environmental Pollutants Generated by the Petroleum Industry

Energies, Год журнала: 2023, Номер 16(3), С. 1209 - 1209

Опубликована: Янв. 22, 2023

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.

Bioremediation by in situ biostimulation is an attractive alternative to excavation of contaminated soil. Many remediation methods have been tested with some success; however, due highly variable results realistic field conditions, they not implemented as widely might deserve. To ensure success, should be validated under site-analogous conditions before full scale use, which requires expertise and local knowledge the implementers. The focus here on indigenous microbial degraders evaluation their performance. Identifying removing biodegradation bottlenecks for degradation organic pollutants essential. Limiting factors commonly include: lack oxygen or electron acceptors, low temperature, essential nutrients. Additional factors: bioavailability contaminating compound, pH, distribution contaminant, soil structure moisture, cases, potential may amended bioaugmentation. Methods remove these are discussed. Implementers also prepared combine use them sequence. Chemical/physical means used enhance biostimulation. review suggests tools assessing sustainability, life cycle assessment, risk assessment. help entrepreneurs, decision makers, developers future, we suggest founding a database otherwise seldom reported unsuccessful interventions, well artificial intelligence (AI) assist site decision-making.

Discover Chemical Engineering, Год журнала: 2024, Номер 4(1)

Опубликована: Янв. 5, 2024

Abstract Foam formation is a massive challenge in submerged aerated bioprocesses, e.g., beer fermentation. While the use of antifoam may easily overcome foaming at laboratory scale, it often an unattractive solution since remains future upscaling, as reduced mass transfer and extra steps product purification analytics result increased costs. Interestingly, number studies tackling this relatively low, although literature suggests range alternatives, from avoiding to means controlling or even using situ removal. Here we give overview topic five subsections. (1) We argue that sound understanding molecular origin can facilitate solutions for overcoming while introducing some long-known challenges (i.e., fermentation). then review (2) apparent avoidance foam before (3) summarize possibilities reduce control after its formation. Subsequently, (4), discuss possible take advantage formation, example, via fractionation Finally, (5), provide microbial strain engineering approaches cope with aspects fermentations. With review, would like sensitize inform interested reader offering current expert, particularly regard special issue Discover Chemical Engineering.
