Combination of supercritical CO2 and high-power ultrasound for the inactivation of fungal and bacterial spores in lipid emulsions [PDF]
Ultrasonics Sonochemistry, 2021 For the first time, this study addresses the intensification of supercritical carbon dioxide (SC-CO2) treatments using high-power ultrasound (HPU) for the inactivation of fungal (Aspergillus niger) and bacterial (Clostridium butyricum) spores in oil-in ...

Cell-specific cargo delivery using synthetic bacterial spores [PDF]
Cell Reports, 2023 Summary: Delivery of cancer therapeutics to non-specific sites decreases treatment efficacy while increasing toxicity. In ovarian cancer, overexpression of the cell surface marker HER2, which several therapeutics target, relates to poor prognosis.

Evaluation of Microencapsulation Techniques for MICP Bacterial Spores Applied in Self-Healing Concrete [PDF]
Scientific Reports, 2019 Concrete cracks must be repaired promptly in order to prevent structural damage and to prolong the structural life of the building (or other such construction). Biological self-healing concrete is a recent alternative technology involving the biochemical

Thioflavin-T does not report on electrochemical potential and memory of dormant or germinating bacterial spores [PDF]
mBio, 2023 Bacterial spores are metabolically dormant, resistant to microbicides, and vectors of food spoilage and diseases, while germinated spores are easy to kill. Consequently, understanding germination mechanisms may facilitate the development of “germinate-to-

A Cell‐Penetrating Peptide‐Derived Fluorescent Probe for Selective Isolation of Bacterial Spores [PDF]
Microbial BiotechnologyIn this study, we identify a peptide discovered through fluorescence‐based screening of a cell‐penetrating peptide (CPP) library that preferentially associates with bacterial spores and evaluate its utility as a fluorescence‐guided tool for spore ...

Understanding the Effects of High Pressure on Bacterial Spores Using Synchrotron Infrared Spectroscopy [PDF]
Frontiers in Microbiology, 2020 Bacterial spores are extremely resistant life-forms that play an important role in food spoilage and foodborne disease. The return of spores to a vegetative cell state is a three-step process, these being activation, germination, and emergence.
