Interaction between polyethylene terephthalate (PET) microplastic and microalgae (Scenedesmus spp.): Effect on the growth, chlorophyll content, and hetero-aggregation

open access: yesEnvironmental Advances, 2023
Microplastics have become a global environmental concern due to their ubiquitous presence and persistence in the environment and have been identified as a major pollutant in aquatic environments.

Living Electronics: Microbial Metabolism as Batteries, Resistors, and Capacitors

open access: yesAdvanced Electronic Materials, EarlyView.
Three microorganisms are assigned the three elementary roles of a circuit on one sheet of paper. Dormant Bacillus subtilis spores germinate to switch the power source on; a photosynthetic Synechocystis biofilm sets resistance by the color and intensity of light; and a respiring Shewanella oneidensis biofilm stores charge. Together they form a printable

Enzyme Immobilization on Polysaccharides for Biofilm Degradation in Tissue Constructs

open access: yesJournal of Pure and Applied Microbiology
The surfaces of medical devices can quietly become breeding grounds for resilient bacterial colonies, which pose a significant risk to patients. These microorganisms form complex communities embedded within a self-produced extracellular matrix known as ...

Biofilms: Microbial Life on Surfaces

open access: yesEmerging Infectious Diseases, 2002
Microorganisms attach to surfaces and develop biofilms. Biofilm-associated cells can be differentiated from their suspended counterparts by generation of an extracellular polymeric substance (EPS) matrix, reduced growth rates, and the up- and down ...

Production of extracellular polymeric substances (EPS) by benthic diatoms: effect of irradiance and temperature [PDF]

open access: yesMarine Ecology Progress Series, 2002
An axenic culture of Cylindrotheca closterium and a natural community of benthic diatoms were used to study the effect of temperature and irradiance on the production of extracellular polymeric substances (EPS). In the culture, results depended on the growth stage of the algae and on whether absolute values or biomass-related values were considered ...

The Collective Power of Bacteria as a Blueprint for Emergent Intelligence

open access: yesAdvanced Intelligent Systems, EarlyView.
Small cells, powerful collectives. Bacteria demonstrate how sophisticated behaviors can emerge from many simple individuals working together. We explore the remarkable world of bacterial communities and the mechanisms that underpin their complex emergent behaviors, enabling impressive adaptability, robustness, and responsiveness to changing ...

Anti-Biofilm Strategies: A Focused Review on Innovative Approaches

open access: yesMicroorganisms
Biofilm (BF) can give rise to systemic infections, prolonged hospitalization times, and, in the worst case, death. This review aims to provide an overview of recent strategies for the prevention and destruction of pathogenic BFs.

Extracellular Vesicles‐Based Biological Macromolecule Delivery Systems: Biogenesis, Characterization, and Emerging Clinical Applications

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are nanoscale membrane‐bound structures that play a pivotal role in intercellular communication by transporting bioactive molecules, including proteins, lipids, nucleic acids, and organelles, between cells. Originating from the endosomal pathway, EVs reflect the physiological and pathological status of their parent

Identification of Putative Cellulose Synthase Gene xcsA2 Required for c‐di‐GMP‐Induced Biofilm Formation and Cell Aggregation in Synechococcus elongatus PCC 7942

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Synechococcus elongatus PCC 7942 is a widely used model cyanobacterium for diverse research fields and for bioproduction applications owing to its ease of cultivation, genetic modification, and ability to fix CO2. We found that a laboratory strain of S. elongatus PCC 7942 expressing the ydeH gene from E.
