Characterization of The Electrical and Optical Properties of Ultrabithorax Fusion Fibers for Biosensing

open access: yesAdvanced Materials Technologies, EarlyView.
In this work, Ultrabithorax (Ubx) protein fusions with myoglobin, EGFP and mCherry are investigated and proposed for biosensing applications. For the first time, FRET calculations based on fluorescent lifetime measurements are presented for Ubx‐based protein fusions.

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,

Comparative characterization of silver nanoparticles synthesized by spore extract of Bacillus subtilis and Geobacillus stearothermophilus [PDF]

open access: yesNanomedicine Journal, 2018
Objective(s): Silver nanostructures have gathered remarkable attention due to their applications in diversefields. Researchers have recently demonstrated that bacterial spores are capable of reducing silver ions toelemental silver leading to formation of

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 ...

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.

The Prevalence and Control of Bacillus and Related Spore-Forming Bacteria in the Dairy Industry [PDF]

open access: yes, 2015
peer-reviewedMilk produced in udder cells is sterile but due to its high nutrient content, it can be a good growth substrate for contaminating bacteria. The quality of milk is monitored via somatic cell counts and total bacterial counts, with prescribed ...

Homeostasis of Gut Microbiota Protects against Susceptibility to Fungal Pneumonia

open access: yesAdvanced Science, EarlyView.
Fungal pneumonia induces inflammation, shown by heightened IL‐6, IL‐1β, TNF‐α levels and a growth in Staphylococcus in the alveolar flora. The gut microbiota, acting through the gut‐lung axis via blood, impacts fungal pneumonia susceptibility by altering lung metabolism and inflammatory responses.

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.

Molecular Physiological Characterization of a High Heat Resistant Spore Forming Bacillus subtilis Food Isolate

open access: yesMicroorganisms, 2021
Bacterial endospores (spores) are among the most resistant living forms on earth. Spores of Bacillus subtilis A163 show extremely high resistance to wet heat compared to spores of laboratory strains. In this study, we found that spores of B.

Inhibition of RNase to Attenuate Fungal‐Manipulated Rhizosphere Microbiome and Diseases

open access: yesAdvanced Science, EarlyView.
Fusarium graminearum uses its virulence effector Fg12, a fungal RNase, to manipulate the host rhizosphere microbiome and promote infection. Guanosine monophosphate (GMP) blocks Fg12's RNase activity. This reveals a key pathogen‐microbiota interaction mechanism and proposes GMP as a targeted strategy to disarm this core fungal effector, offering a ...
