Biosurfactants Used in the Bioremediation of Soils Contaminated With Hydrocarbons - Overview of the State of the Art and Future Perspectives.

Background: The increasing industrialization and hydrocarbon use have led to concerning soil contamination. Oil spills and improper disposal of oily waste pose threats to ecosystems and human health. The recovery of these environments is essential, but separating oily components from soil remains challenging.

Production and characterization of the lipopeptide with anti-adhesion for oral biofilm on the surface of titanium for dental implants.

Titanium implants are subject to bacterial adhesion and peri-implantitis induction, and biosurfactants bring a new alternative to the fight against infections. This work aimed to produce and characterize the biosurfactant from Bacillus subtilis ATCC 19,659, its anti-adhesion and antimicrobial activity, and cell viability. Anti-adhesion studies were carried out against Streptococcus sanguinis, Staphylococcus aureus, Fusobacterium nucleatum, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Proteus mirabilis as the minimum inhibitory concentration and the minimum bactericidal concentration.

Exploring the biofilm inhibitory potential of Candida sp. UFSJ7A glycolipid on siliconized latex catheters.

Biosurfactants, sustainable alternatives to petrochemical surfactants, are gaining attention for their potential in medical applications. This study focuses on producing, purifying, and characterizing a glycolipid biosurfactant from Candida sp. UFSJ7A, particularly for its application in biofilm prevention on siliconized latex catheter surfaces.

Effect of DMPEI coating against biofilm formation on PVC catheter surface.

Urinary tract infections (UTIs) are a significant cause of morbidity in healthcare systems and are prominently associated with applying urethral catheters, particularly in surgeries. Polyvinyl chloride (PVC) is extensively utilized in the fabrication of catheters. Biofilms, complex polymeric constructions, provide a protective milieu for cell multiplication and the enhancement of antibiotic resistance.

Recent Patents on the Industrial Application of Biosurfactants.

Background: Biosurfactants are natural bioactive compounds produced from fungi, bacteria and plants. These molecules have several properties that enable them to be involved in various industrial applications. The surface-active properties of biosurfactants allow their use in various sectors, such as agriculture, health, cosmetics, bioremediation/ petroleum, mining, and bioprocess.

Impact of DMPEI on Biofilm Adhesion on Latex Urinary Catheter.

Background: Microorganisms can migrate from the external environment to the patient's organism through the insertion of catheters. Despite being indispensable medical device, the catheter surface can be colonized by microorganisms and become a starting point for biofilm formation. Therefore, new technologies are being developed in order to modify surfaces to prevent the adhesion and survival of microorganisms.
