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.

At the nexus of three kingdoms: the genome of the mycorrhizal fungus Gigaspora margarita provides insights into plant, endobacterial and fungal interactions. [PDF]

open access: yes, 2020
As members of the plant microbiota, arbuscular mycorrhizal fungi (AMF, Glomeromycotina) symbiotically colonize plant roots. AMF also possess their own microbiota, hosting some uncultivable endobacteria.

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.

Enhanced self-healing capacity in cementitious materials by use of encapsulated carbonate precipitating bacteria : from proof-of-concept to reality [PDF]

open access: yes, 2013
In this study, two bacteria-based self-healing systems were developed for the proof-of-concept and approach to a realistic self-healing. A self-healing system with glass capillaries and silica sol gel carried bacterial cells was first built.

Inactivating and damaging properties of the disinfectant “MultiDez” when exposed to bacteria and spores

open access: yesHeliyon, 2023
Disinfectants play a crucial role in controlling the spread of infectious diseases caused by bacteria and spore-forming organisms. Bacteria and spores can persist on surfaces and in the environment for extended periods, posing a significant risk to ...
