Detection of Bacterial Endospores in Soil by Terbium Fluorescence

open access: yesInternational 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]

open access: yesJournal 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.

Fungal Antimicrobial Resistance: Mechanisms, Drivers, and Global Clinical Burden

open access: yesChemFoodChem, EarlyView.
ABSTRACT Fungal antimicrobial resistance (AMR) is a growing concern for world health caused by an increase in multidrug‐resistant infections, an increase in environmental reservoirs, and the ineffectiveness of current antifungal treatments. Fungal infections continue to be largely excluded from AMR initiatives while causing over 1.6 million deaths ...

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

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

Bacillus sphaericus mosquito pathogens in the aquatic environment

open access: yesMemorias do Instituto Oswaldo Cruz, 1995
The fate of Bacillus sphaericus spores in the aquatic environment was investigated by suspending spores in dialysis bags in fresh and seawater. Spore viability was lost more rapidly in seawater. Neither B. sphaericus nor B. thuringiensis israelensis (B.t.

RNA Dynamics in Aging Bacterial Spores [PDF]

open access: yesCell, 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.

Living Microbial Drugs

open access: yesChemistry – A European Journal, EarlyView.
The introduction outlines the review scope. Microbial cell factories as living drugs cover host–gut microbiota, bacteria, yeast, and other microbial systems, with comparative host advantages. Engineering strategies include synthetic circuits, quorum sensing, and memory.

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

open access: yesDroplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Distribution of bacterial spores in supermarkets

open access: yesHygiene and sanitation, 2019
This work presents results of the study on the environment prevalence of spores of aerobic bacteria, which are of potential danger to human health. The investigation of swabs from handles of supermarket trolleys revealed on their surface the presence of a large number of spores of unrelated pathogenic bacteria carrying as antibiotic resistance genes ...

Waste to Hydrogen: Transforming Food Waste Into Biohythane (Bio‐H2 + Bio‐CH4) in a Two‐Stage Reactor With the Aid of a Metal‐Ion Catalyst

open access: yesEnergy Science &Engineering, EarlyView.
This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity
