Microorganisms showed unique mechanisms to resist and detoxify harmful metals in response to pollution. This study shows the relationship between presence of heavy metals and plant growth regulator compounds. Additionally, the responses of Rhodotorula mucilaginosa YR29 isolated from the rhizosphere of Prosopis sp.

- Invasive infections from filamentous fungi, particularly Aspergillus terreus, have risen due to weakened immune responses, and this fungus shows resistance to common treatments like amphotericin B, leading to higher mortality rates.
- The study identifies a clinical strain of A. terreus and examines its ability to form biofilms using advanced microbiological techniques, revealing important stages of biofilm development through SEM-HR (Scanning Electron Microscopy in High Resolution).
- Additionally, the research characterizes the biofilm's structure and chemical composition, identifying key components like proteins, carbohydrates, nucleic acids, and notably, lipid components, marking the first report of lipid-type biofilms in this fungal species.
Background: Biofilms are a highly structured consortia of microorganisms that adhere to a substrate and are encased within an extracellular matrix (ECM) that is produced by the organisms themselves. Aspergillus fumigatus is a biotechnological fungus that has a medical and phytopathogenic significance, and its biofilm occurs in both natural and artificial environments; therefore, studies on the stages observed in biofilm formation are of great significance due to the limited knowledge that exists on this specific topic and because there are multiple applications that are being carried out.
Results: Growth curves were obtained from the soil and clinical isolates of the A.
Background: Microorganisms of different species interact in several ecological niches, even causing infection. During the infectious process, a biofilm of single or multispecies can develop. Aspergillus fumigatus and Staphyloccocus aureus are etiologic agents that can cause infectious keratitis.
