A new edible biofilm developed by Brazilian researchers extends the shelf life of strawberries by up to 11% while preserving their freshness, taste, and aroma. The film, made from pomegranate peel extract and natural polymers, acts as a barrier to microorganisms, moisture loss, and gas exchange.
Scientists at University of California - Riverside discovered a chemical produced by plants that prevents bacterial biofilm formation. This breakthrough offers potential advances in healthcare and industrial settings, where biofilms cause significant problems.
Researchers discovered that PYY prevents the fungus Candida albicans from turning into its more dangerous form while allowing commensal yeast forms to flourish. This peptide functions as an antimicrobial agent, playing a vital role in maintaining fungal commensalism in the gut.
Scientists have identified a promising biological solution to control dollar spot, a devastating disease on golf courses and other turfgrass areas. The beneficial microbe UD1022, patented by the University of Delaware, shows potential in preventing the fungus' growth and may even trigger systemic resistance.
A WVU researcher is working to understand the unknowns about microorganisms growing inside pipes that bring drinking water to homes and businesses. Biofilms can be detrimental to drinking water quality, but the researcher aims to develop strategies for maintaining water quality throughout complex infrastructures.
Researchers demonstrate a model for developing probiotic therapies to modulate the microbiome by targeting intestinal biofilms and identifying beneficial microbial strains. The study showed positive effects in reducing GI symptoms and improving overall well-being in healthy individuals.
A study by University of Wisconsin-Madison researchers identified key proteins in fungal biofilms that control resistance to antifungal drugs and dispersal throughout the body. These proteins provide potential drug targets to impair a pathogen's antimicrobial defenses, including the fungus Candida albicans.
GlycoNet researchers have identified a key enzyme, Agd3, critical for biofilm formation in Aspergillus fumigatus. Without this enzyme, the biofilm does not form, and the fungus is weakened. The team has also discovered a new family of carbohydrate-processing enzymes that has not been previously characterized.
When non-motile E. coli and motile A. baylyi are mixed, stunning floral patterns emerge due to differences in growth rate, motility, and friction against the agar surface. This phenomenon has important implications for understanding growing biofilms.
A recent grant from the National Institutes of Health will support a study investigating the interaction between gut bacteria and fungi in Crohn's disease. The research aims to identify genetic mechanisms underlying these interactions and develop novel antifungal and probiotic strategies to decrease symptoms.
Researchers at Case Western Reserve University have identified a novel probiotic mix that can weaken and break apart stubborn microbial biofilm communities in the gut, which are often resistant to antibiotics. The study suggests this probiotic could help patients with gastrointestinal diseases avoid harmful biofilms that worsen symptoms.
Researchers identified alexidine dihydrochloride as a pan-antifungal compound with low mammalian cell toxicity and efficacy against biofilms. The compound potentiates fluconazole's effectiveness and eradicates biofilms in mice central venous catheters.
Researchers discovered that bacteria and fungus working together make biofilm on teeth more pathogenic and difficult to remove. A combination of fluconazole and povidone iodide effectively treats the biofilm by disrupting the protective matrix produced by bacteria.
Scientists at McGill University Health Centre develop novel enzyme technology that prevents and breaks down biofilms, exposing microbes to antibiotics and host defenses. This approach has huge potential to combat biofilm-associated infections responsible for thousands of deaths across North America.
Researchers found that mixed bacterial-fungal biofilms in chronic wounds are associated with poor outcomes and longer healing times. The study identifies the most abundant fungi species, including Cladosporium herbarum and Candida albicans, which can hinder healing.
A new study found that no disinfectant completely removes bacterial biofilms from dental water lines, posing a significant infection risk. Researchers recommend preventing the formation of biofilms as key to keeping lines clean, and suggest using good quality water, prevention disinfectants, and avoiding stagnation.
Campylobacter infection affects millions more than Salmonella, with antibiotic resistance a growing concern. Researchers seek to understand biofilm formation and regulate CsrA's role in making the sugar coating that enables bacterial survival.
A new study found that pharmaceuticals, including antihistamines, alter biofilm communities in streams, leading to reduced photosynthesis and microbial respiration. The most striking effect was observed with diphenhydramine, which caused a 99% decrease in photosynthesis and changed bacterial species present in the biofilms.
A $1.7 million grant will fund research on biofilm formation in dental stomatitis, a fungal infection affecting 50-75% of denture wearers. The study aims to determine the role of biofilms in disease development and develop novel immunotherapies targeting biofilm growth.
A study by Penn State researchers found Fusarium fungus in nearly 70% of sink drains, posing a significant health risk. The fungus can cause opportunistic and fatal infections, particularly among individuals with compromised immune systems.
A UI biologist found that Candida albicans can form two types of biofilms: a traditional pathogenic one and a second sexual one. The discovery reveals that 90% of cells colonizing humans make resistant, non-sexually competent biofilms. A minority of cells form highly permeable and penetrable biofilms that support mating
Researchers have discovered that Candida albicans produces two distinct types of biofilms: a traditional pathogenic one and a second sexual type. The majority of cells forming these biofilms are sexually incompetent, but a minority are sexually competent and form highly permeable biofilms.
Researchers found that biofilms composed of resistant microbial cells are the cause of corneal infections fueled by soft contact lens use. They recommend improved testing with modern fungal strains and adherence to lens care best practices.
Researchers discovered that GroEL1 oversees production of fatty acids necessary for biofilm growth, which are absent in bacteria lacking the chaperone protein. Understanding this mechanism could lead to new ways to develop effective drugs to fight TB and other mycobacterial infections.
Researchers at Whitehead Institute found key gene FLO11 required for fungal biofilm formation, which can cause serious infections in hip replacements. The discovery offers hope for preventing such infections in the future by understanding how fungi stick to plastic surfaces.
Researchers at Georgia State University found over 15 types of fungi growing in car AC foam and glue, causing bad smells and allergic reactions. Sulphur-containing compounds are also responsible for the odors.
