Biosurfactant Production by Pseudomonas aeruginosa Strain LTR1 and its Application

Biointerface Research in Applied Chemistry, Год журнала: 2022, Номер 13(1), С. 10 - 10

Опубликована: Янв. 7, 2022

On the circumstances of growing market biosurfactants all over globe, presented study focused on characterization produced by newly isolated and reported as biosurfactant producer strain Pseudomonas aeruginosa LTR1. Additionally, production media physiological factors are optimized using a one factor at time (OFAT) approach for maximum production. Its efficacy antimicrobial emulsification activities was determined. P. LTR1 utilized carbon sources provided, 9.5 g/L in soybean oil supplemented minimal salts medium (MSM). The critical micelle concentration (CMC) determined 12 mg/L can reduce surface tension from 72 mN/m to 31 mN/M. characterized biochemical analysis Fourier transform infrared spectroscopy (FTIR) not protein nature, possibly glycolipid type biosurfactant. It has shown good various hydrocarbon tested here. In addition, it acts an antibiofilm agent with minimum inhibitory required 50 % biofilms reduction 30.95 µg/mL suggesting potential. surface-active properties, emulsification, activities, demonstrating its potential application areas like industry, especially tank cleaning, bioremediation spills sea or soil, candidates antimicrobial.

Enhanced Removal of Hydrocarbons from Crude Oil Sludge through Phytoremediation with Biosurfactant-producing Rhizobacteria

IOP Conference Series Earth and Environmental Science, Год журнала: 2024, Номер 1307(1), С. 012009 - 012009

Abstract Discharge of crude oil (or its products) during the extracting, refining, and transporting into environment have caused serious environmental distress due to their highly hydrophobic resistance, persistence in nature very difficult be remediated from environment. Therefore, an environmentally conscious approach enhance bioavailability solubility) petroleum hydrocarbon pollutants soil involves utilization biosurfactants. Biosurfactants play a crucial role enhancing desorption solubilization hydrocarbons, facilitating assimilation by microorganisms. This research investigated application biosurfactant supplementation derived purified rhizobacteria Scirpus grossus , which are capable producing biosurfactants degrading context phytoremediation. The sludge used this study was obtained industrial area containing 56,600±3;900 mg/kg total (TPH). inoculated with biosurfactant, sodium dodecyl sulfate (SDS) as commercial surfactant only presence S. vegetated tanks monitored for 90 days greenhouse. results indicated that growth addition improved new saplings were produced. After 90-day exposure period, removal efficiency TPH demonstrated significant increases, reaching 90.3%, 84.1%, 73.7% when treated biosurfactant+S. SDS+S. respectively. These percentages notably higher compared non-planted control crates (CC) where 17.9%. provide evidence introduction through inoculation can elevate organic pollutants, consequently augmenting microbial degradation soil.

BIOAUGMENTATION AS BIOREMEDIATION APPROACH FOR CONTAMINATED SOIL: A REVIEW

Jurnal Teknologi, Год журнала: 2024, Номер 86(5), С. 89 - 102

Опубликована: Авг. 12, 2024

The inevitable impacts by the emerging urbans developments towards quality and function of soil have raised concerns for future environment consequences. Pollutants that evolved from anthropogenic activities including heavy metals, pesticides, petroleum hydrocarbons (TPH) polycyclic aromatic (PAHs) tend to be persistent within hence, contribute long term effects human’s health. Researchers discovered success bioaugmentation as part bioremediation an approach degrading pollutants employing microorganisms (i.e., bacteria or fungi) enhance removal pollutants. concept, mechanism, method, factors affecting is studied past years explore thorough process bioaugmentation. It claimed directly related microbial activity three different approaches (autochthonous, allochthonous, genetically engineering microorganisms). pH, temperature, moisture, oxidation reduction potential are key prospects efficiency. application each targeted pollutant certify its capability degrading, removing, transforming into less toxic components.

Efficient and eco-friendly mixed bacterial consortium for petroleum wastewater treatment: Effect of the bio-augmentation and biosurfactant addition on hydrocarbon biodegradation

Journal of Dispersion Science and Technology, Год журнала: 2023, Номер 45(9), С. 1691 - 1701

Опубликована: Июль 27, 2023

In the present investigation, we aimed to study biological petroleum wastewater treatment. A bioprocess based on use of a mixed bacterial consortium along with addition Biosurfactant (BioS) and bioaugmentation BioS producing strains were evaluated. The was combination two capacity metabolize hydrocarbons, Baci B201. Two other BH1 BSS2 selected for their ability degrade hydrocarbons as well produce also exploited. effect ex-situ in-situ produced hydrocarbon biodegradation compared. Obtained results demonstrated moderate remove crude oil from contaminated water about 47% consortium. best improvement 84% obtained when adding derived solely. However, exhibited better results. Regarding characteristics, note decrease COD/BOD5 Ratio reach 2.64. Thus, became easily biodegradable. described is great interest bioremediation effluents. enhanced removal.
