Bacillus cereus spores release alanine that synergizes with inosine to promote germination. [PDF]

PLoS ONE, 2009
BACKGROUND:The first step of the bacterial lifecycle is the germination of bacterial spores into their vegetative form, which requires the presence of specific nutrients.

Resilient living materials built by printing bacterial spores

bioRxiv, 2019
Materials can be made multifunctional by embedding them with living cells that perform sensing, synthesis, energy production, and physical movement. A challenge is that the conditions needed for living cells are not conducive to materials processing and ...

Bacterial Spores as Vaccine Vehicles [PDF]

Infection and Immunity, 2003
ABSTRACT For the first time, bacterial spores have been evaluated as vaccine vehicles. Bacillus subtilis spores displaying the tetanus toxin fragment C (TTFC) antigen were used for oral and intranasal immunization and were shown to generate mucosal and systemic responses in a murine model.

Arbuscular mycorrhizal fungal spores host bacteria that affect nutrient biodynamics and biocontrol of soil-borne plant pathogens

Biology Open, 2011
Summary The aim of this research was to isolate and characterize bacteria from spores of arbuscular mycorrhizal fungi (AMF). We designated these bacteria ‘probable endobacteria’ (PE). Three bacterial strains were isolated from approximately 500 spores of

Perturbing Tandem Energy Transfer in Luminescent Heterobinuclear Lanthanide Coordination Polymer Nanoparticles Enables Real-Time Monitoring of Release of the Anthrax Biomarker from Bacterial Spores.

Analytical Chemistry, 2018
Lanthanide-based luminescent sensors have been widely used for the detection of the anthrax biomarker dipicolinic acid (DPA). However, mainly based on DPA sensitization to the lanthanide core, most of them failed to realize robust detection of DPA in ...

Research Progress of Cold Plasma-induced Inactivation of Bacterial Spores

Shipin gongye ke-ji
Spores are the main dormant forms of some bacteria under harsh environment conditions, which are widely distributed in nature. Bacterial spores have a rigid structure, which helps resist to environmental stresses such as heat and ultraviolet radiation ...

Eriochrome Black T-Eu3+ Complex as a Ratiometric Colorimetric and Fluorescent Probe for the Detection of Dipicolinic Acid, a Biomarker of Bacterial Spores.

Analytical Chemistry, 2018
A novel ratiometric colorimetric and fluorescent dual probe based on Eriochrome Black T (EBT)-Eu3+ complex was designed to detect dipicolinic acid (DPA), a major constituent of bacterial spores, with high sensitivity and selectivity.

Quantitative and Sensitive RNA Based Detection of Bacillus Spores

Frontiers in Microbiology, 2014
The fast and reliable detection of bacterial spores is of great importance and still remains a challenge. Here we describe a direct RNA based diagnostic method for the specific detection of viable bacterial spores which does not depends on an enzymatic ...

Self-repairing of shrinkage crack in mortar containing microencapsulated bacterial spores

Journal of Materials Research and Technology, 2023
The purpose of this research work was to evaluate the efficacy of microbially induced calcite precipitation (MICP) method in shrinkage crack repairing. Portland cement was combined with sand, bacterial spores, water, and nutrients to prepare self-healing

Effect of two nanoparticles and bacteria spores on some biological aspects of waxworm Galleria mellonella (Lepidoptera;Pyralidae)

NTU Journal of Pure Sciences, 2022
The aim of this study is to control the major Waxworm Galleria mellonella, pests that, cause damage to honeybee colonies due to feeding their larvae on wax combs using safe alternatives such as nanomaterials and biological control using spores of ...
