“…Biosurfactant is an amphipathic molecule made up of hydrophobic and hydrophilic moieties ( Lal et al, 2018 ; Singh et al, 2018 ). Bacillus and Pseudomonas have previously been identified as potential biosurfactant producers for the removal of hazardous organic compounds and heavy metals from contaminated environments ( Ambust et al, 2021 ; Ratna and Kumar, 2022 ). In this study, strains T7 and M2 showed biosurfactant production, and these strains were combined with other strains and included in consortium ERM C-1.…”

The indiscriminate use of organophosphate insecticide chlorpyrifos in agricultural crops causes significant soil and water pollution and poses a serious threat to the global community. In this study, a microbial consortium ERM C-1 containing bacterial strains Pseudomonas putida T7, Pseudomonas aeruginosa M2, Klebsiella pneumoniae M6, and a fungal strain Aspergillus terreus TF1 was developed for the effective degradation of chlorpyrifos. Results revealed that microbial strains were not only utilizing chlorpyrifos (500 mg L–1) but also coupled with plant growth-promoting characteristics and laccase production. PGP traits, that is, IAA (35.53, 45.53, 25.19, and 25.53 μg mL–1), HCN (19.85, 17.85, 12.18, and 9.85 μg mL–1), and ammonium (14.73, 16.73, 8.05, and 10.87 μg mL–1) production, and potassium (49.53, 66.72, 46.14, and 52.72 μg mL–1), phosphate (52.37, 63.89, 33.33, and 71.89 μg mL–1), and zinc (29.75, 49.75, 49.12, and 57.75 μg mL–1) solubilization tests were positive for microbial strains T7, M2, M6, and TF1, respectively. The laccase activity by ERM C-1 was estimated as 37.53, 57.16, and 87.57 enzyme U mL–1 after 5, 10, and 15 days of incubation, respectively. Chlorpyrifos degradation was associated with ERM C-1 and laccase activity, and the degree of enzyme activity was higher in the consortium than in individual strains. The biodegradation study with developed consortium ERM C-1 showed a decreased chlorpyrifos concentration from the 7th day of incubation (65.77% degradation) followed by complete disappearance (100% degradation) after the 30th day of incubation in the MS medium. First-order degradation kinetics with a linear model revealed a high k –day value and low t1/2 value in ERM C-1. The results of HPLC and GC-MS analysis proved that consortium ERM C-1 was capable of completely removing chlorpyrifos by co-metabolism mechanism.

“…Bioremediation is one of the promising and cost-effective technologies that can be adopted to deal with and rehabilitate the contaminated environment. Several kinds of research have been carried out where potential bacteria had been isolated from contaminated sites and applied in either singlet or consortium form to degrade oil components into simpler forms (Das and Mukherjee 2007 ; Patowary et al 2016 ; Tian et al 2018 ; Ali et al 2020 ; Zhang et al 2020 ; Ambust et al 2021 ). Bioremediation mainly comprises two prime strategies; one is bio-stimulation, and the other is bioaugmentation.…”

Crude petroleum oil spillage is becoming a global concern for environmental pollution and poses a severe threat to flora and fauna. Bioremediation is considered a clean, eco-friendly, and cost-effective process to achieve success among the several technologies adopted to mitigate fossil fuel pollution. However, due to the hydrophobic and recalcitrant nature of the oily components, they are not readily bioavailable to the biological components for the remediation process. In the last decade, nanoparticle-based restoration of oil-contaminated, owing to several attractive properties, has gained significant momentum. Thus, intertwining nano- and bioremediation can lead to a suitable technology termed ‘nanobioremediation’ expected to nullify bioremediation’s drawbacks. Furthermore, artificial intelligence (AI), an advanced and sophisticated technique that utilizes digital brains or software to perform different tasks, may radically transfer the bioremediation process to develop an efficient, faster, robust, and more accurate method for rehabilitating oil-contaminated systems. The present review outlines the critical issues associated with the conventional bioremediation process. It analyses the significance of the nanobioremediation process in combination with AI to overcome such drawbacks of a traditional approach for efficiently remedying crude petroleum oil-contaminated sites.

“…For this reason, the choice of surfactants and the appropriate amount of surfactant are primary aspects that must be reviewed before developing effective strategies for disease management [110,111] . Traditional synthetic surfactants, including Tween‐20, Silwet L‐77, Agral‐90, Cohere, and Triton X‐100, are among the foremost widely utilized chemical surfactants for plant disease management [112,113] . These surfactants have proven better insecticidal ability in in‐vivo and in‐vitro studies.…”

Chemical surfactants have raised concerns due to their negative impact on ecosystems, prompting the search for ecofriendly alternatives. Biosurfactants derived from microorganisms offer a promising solution. These biomolecules are less harmful and can replace toxic pesticide surfactants. Biosurfactants have shown potential in agriculture for food digestion, crop protection, soil fertility, disease management, antibacterial properties, and biofilm prevention. They eliminate plantpathogens and improve nutrient availability, supporting plantgrowth. Rhamnolipids, produced by Pseudomonas, reduce surface tension, are used as wetting agents and emulsifiers in agriculture, and antimicrobial and anti-inflammatory medications. Surfactin, a biosurfactant from Bacillus subtilis, improves plant development, controls plant diseases, and fights pathogens and diseases. Candida bombicola yeast produces sopho-rolipids, biodegradable surfactants with antibacterial, anticancer, and anti-inflammatory properties. Pseudozyma yeast produces mannosylerythritol lipids (MELs), which biocontrol fungus and have antibacterial, anticancer, and immunomodulatory activities. Biosurfactants also hold potential in pharmaceuticals, functioning as antioxidants, exhibiting antibacterial and anticancer activities, and acting as drug-delivery systems. However, challenges in biosurfactant production include varying research methods, limited production organism sources, and cost implications for large-scale manufacturing. This minireview explores microbiologically produced biosurfactants, their regulatory parameters, their applications in optimizing soil health and controlling plant infections, and their potential roles in the pharmaceutical sector.* Ability to tolerate high temperatures, * Ability to tolerate variation in pH, * Ability to tolerate saline environment, * Biodegradable character, * Low or non-toxic nature, and * Effective selectivity.Generally, biosurfactants are amphipathic molecules characterized by hydrophobic and hydrophilic components. Generally, the hydrophobic component consists of a very long chain of fatty acids connected. The hydrophilic component comprises positively, negatively, or amphoterically charged ions. In contrast to their chemical analogs, biosurfactants are often categorized by their CMC concentration, low or high molecular weight, the microorganism type that produce biosurfactant, and their mode of action. Low molecular weight biosurfactants are most frequently reported as glycolipids, phospholipids, and [a]
