Summary: This study tested the use of a solution called effective microorganisms (EM) to remove cadmium from soil. The experimental results showed that EM had a cadmium removal efficiency of 90.5% after 7 days of electrokinetic (EK) treatment. EM's biosurfactant property allowed them to penetrate deeply into the soil and dissolve a high quantity of pollutants.

Summary: To protect human and environmental health, researchers are focusing on discovering and developing new molecules with high biocompatibility and biodegradability. Surfactants are particularly urgent in this matter, and biosurfactants derived from microorganisms are a promising alternative. Rhamnolipids, a well-known family of biosurfactants, have been extensively studied for their production and physicochemical characterization, although a clear structure-function relationship is still lacking. This review aims to provide a comprehensive discussion of the physicochemical properties of rhamnolipids under different solution conditions and their structure, while also addressing unresolved issues for their potential replacement of conventional surfactants.

Summary: A total of 71 bacteria were isolated from crude oil-contaminated soil samples. Thirteen isolates were selected for further molecular identification, and they were identified as belonging to Pseudomonas, Acinetobacter, Bacillus, and Priestia genera. Pseudomonas aeruginosa strain TBA-B58 showed the highest enzymatic activity for lipolytic and esterolytic activities, while the glycolipid-type biosurfactant from this strain achieved the highest reduction in surface tension. Acinetobacter baumanni strains TBA-B45 and TBA-B56 demonstrated notable emulsification activity against toluene and benzene. These biosurfactant-producing strains have potential applications in the bioremediation of crude oil hydrocarbons.

Summary: This work describes the design and synthesis of three new Troger's base appended bis-carbazole units via the oxidative coupling method aiming to achieve solid-state luminescent materials. The careful control of the electronic attributes of these molecules allowed the preparation of novel luminescent materials possessing high thermal stabilities and favorable bandgaps for electron mobility indicating their potential applications as sensory materials or in optoelectronic devices. Additionally, one of the materials demonstrated high biocompatibility against Escherichia coli and was found to effectively stain dead bacterial cells over live cells, providing a promising strategy for bacterial cell death assessment based on fluorescence upon the addition of antibacterial agents.

Summary: Phytopathogens have serious implications on food production, but biocontrol strategies involving the use of biomaterials offer opportunities for sustainable agriculture. This study investigated the potential of rhamnolipid-BS, fungal chitosan, and chitosan nanoparticles against phytopathogens. The results showed that these compounds exhibited antibacterial and antifungal activities, and their combination showed synergistic or additive effects. The study suggests that the combination of rhamnolipid-BS with fungal chitosan nanoparticles could be a promising eco-friendly and low cytotoxic formulation for future use.
