Antigen-displaying probiotic Bacillus subtilis spores induce subtle, strain-dependent immunomodulation in fish

Frontiers in Marine Science
Despite the availability of commercial vaccines against several pathogens, infectious diseases continue to cause substantial economic losses in aquaculture.

Detection of Bacterial Endospores in Soil by Terbium Fluorescence

International Journal of Microbiology, 2011
Spore formation is a survival mechanism of microorganisms when facing unfavorable environmental conditions resulting in “dormant” states. We investigated the occurrence of bacterial endospores in soils from various locations including grasslands (pasture,

Molecular Kinetics of Reviving Bacterial Spores [PDF]

Journal of Bacteriology, 2013
ABSTRACT Bacterial spores can remain dormant for years, yet they possess a remarkable potential to rapidly resume a vegetative life form. Here, we identified a distinct phase at the onset of spore outgrowth, designated the ripening period.

Beetroot-pigment-derived colorimetric sensor for detection of calcium dipicolinate in bacterial spores.

PLoS ONE, 2013
In this proof-of-concept study, we describe the use of the main red beet pigment betanin for the quantification of calcium dipicolinate in bacterial spores, including Bacillus anthracis.

RNA Dynamics in Aging Bacterial Spores [PDF]

Cell, 2012
Upon starvation, the bacterium Bacillus subtilis enters the process of sporulation, lasting several hours and culminating in formation of a spore, the most resilient cell type known. We show that a few days following sporulation, the RNA profile of spores is highly dynamic.

Pulsed Light Technology in Food Safety and Preservation: Principles, Applications, and Future Directions

Food Chemistry International, EarlyView.
Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.

Bioactive compounds in insects—Composition, extraction, functionality, food applications, and safety concerns

Food Biomacromolecules, EarlyView.
This review synthesizes 94 studies (2000–2025) exploring edible insects as sustainable sources of peptides, lipids, and chitin. Utilizing “green” extraction, these bioactives offer antioxidant and antimicrobial benefits for functional foods. However, addressing safety concerns like allergenicity and heavy metals through standardized frameworks remains ...

A new method of spore separation: preparation of antibiotic modified nanoparticles and its application in spore-vegetative cell mixed system

Food Science and Human Wellness
Bacterial spores commonly co-exist with vegetative cells, presenting challenges in spore separation and detection. The separation of spores is a crucial process for laboratory research and the detection of spore mechanisms.
