Exploring the biofilm inhibitory potential of Candida sp. UFSJ7A glycolipid on siliconized latex catheters. Braz J Microbiol 2024:10.1007/s42770-024-01431-w. [PMID: 38954220 DOI: 10.1007/s42770-024-01431-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 06/19/2024] [Indexed: 07/04/2024] Open
Abstract
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. The glycolipid was extracted and characterized, revealing a critical micellar concentration (CMC) of 0.98 mg/mL, indicating its efficiency at low concentrations. Its composition, confirmed through Fourier transform infrared spectroscopy (FT-IR) and thin layer chromatography (TLC), identified it as an anionic biosurfactant with a significant ionic charge of -14.8 mV. This anionic nature contributes to its biofilm prevention capabilities. The glycolipid showed a high emulsification index (E24) for toluene, gasoline, and soy oil and maintained stability under various pH and temperature conditions. Notably, its anti-adhesion activity against biofilms formed by Escherichia coli, Enterococcus faecalis, and Candida albicans was substantial. When siliconized latex catheter surfaces were preconditioned with 2 mg/mL of the glycolipid, biofilm formation was reduced by up to 97% for E. coli and C. albicans and 57% for E. faecalis. These results are particularly significant when compared to the efficacy of conventional surfactants like SDS, especially for E. coli and C. albicans. This study highlights glycolipids' potential as a biotechnological tool in reducing biofilm-associated infections on medical devices, demonstrating their promising applicability in healthcare settings.

Abstract
Rhamnolipid biosurfactant produced by Pseudomonas aeruginosa, possesses non-toxicity, environmental compatibility, a wide range of pH (4-8), temperature (4-100 °C), and salinity (1-10%) stability. The application of RLs is worldwide accepted in the pharmaceutical, medicinal, and food industries. It has been used for cytotoxicity efficacy analysis with a limited number of cancerous cell lines. To widen the scope of rhamnolipid application as an anticancer agent, we have studied Di-RLs homolog, 'Rha-Rha-C10-C10' produced by Pseudomonas aeruginosa RA5 against human cancerous cell lines including breast cancer (MCF-7), leukemia (K-562), cervical cancer (HeLa), Lung cancer (HOP-62), and colon cancer (HT-29) in a dose-dependent way. It was purified with silica gel chromatography followed by TLC and mass spectroscopy prior to cytotoxicity analysis. With a tensiometer, critical micelle concentration of Di-RLs was estimated to be 33.92 ± 2 mN/m at 0.2%. Cytotoxicity analysis of Di-RLs on K-562 cell line demonstrated inhibition with GI50 and TGI at < 10 µg/mL and 66.6 µg/mL, after 48 h of application. The morphology of human cancerous cell lines was observed under a laser confocal microscope with the SRB staining method. Further research is recommended to comprehend the Di-RLs as a potential anti-cancer agent.

Abstract
Sophorolipids are highly active green surfactants (glycolipid biosurfactants) getting tremendous appreciation worldwide due to their low toxicity, biodegradability, broad spectrum of applications, and significant biotechnological potential. Sophorolipids are mainly produced by an oleaginous budding yeast Starmerella bombicola using low-cost substrates. Therefore, the recent state-of-art literature information about S. bombicola yeast is hereby provided, especially the underlying production pathways, biosynthetic gene cluster, and regulatory enzymes. Moreover, the S. bombicola offers flexibility for regulating the structural diversity of sophorolipids, either genetically or by varying fermentative conditions. The emergence of advanced technologies like 'Omics and CRISPR/Cas have certainly boosted rational engineering research for designing high-performing platform strains. Therefore, currently available genetic engineering tools in S. bombicola were reviewed, thereby opening up exciting new possibilities for improving the overall bioproduction titers, structural variability, and stability of sophorolipids. Finally, some technical perspectives to address the current challenges were discussed.

Abstract
Glycolipid biosurfactants are natural amphiphiles and have gained particular interest recently in their biodegradability, diversity, and bioactivity. Microbial infection has caused severe morbidity and mortality and threatened public health security worldwide. Glycolipids have played an important role in combating many diseases as therapeutic agents depending on the self-assembly property, the anticancer and anti-inflammatory properties, and the antimicrobial properties, including antibacterial, antifungal, and antiviral effects. Besides, their role has been highlighted as scavengers in impeding the biofilm formation and rupturing mature biofilm, indicating their utility as suitable anti-adhesive coating agents for medical insertional materials leading to a reduction in vast hospital infections. Notably, glycolipids have been widely applied to the synthesis of novel antimicrobial materials due to their excellent amphipathicity, such as nanoparticles and liposomes. Accordingly, this review will provide various antimicrobial applications of glycolipids as functional ingredients in medical therapy.
