Bacterial Spores in Food: Survival, Emergence, and Outgrowth [PDF]

Annual Review of Food Science and Technology, 2016
Spore-forming bacteria are ubiquitous in nature. The resistance properties of bacterial spores lie at the heart of their widespread occurrence in food ingredients and foods. The efficacy of inactivation by food-processing conditions is largely determined by the characteristics of the different types of spores, whereas food composition and storage ...

Blocking Honeybee Preference for Neonicotinoids by Interfering With Dopamine Signaling

Advanced Science, EarlyView.
Honeybees (Apis mellifera) paradoxically prefer nectar containing the harmful neonicotinoid thiamethoxam. This preference is associated with transient brain dopamine elevation during proboscis extension reflex (PER) responses and active feeding, and is reduced by the dopamine receptor antagonist fluphenazine.

Intercropping with potato-onion alters arbuscular mycorrhizal fungi spore-associated bacterial communities of tomato rhizosphere

Frontiers in Microbiology
Intercropping systems optimize soil ecological functions, modulate microbial diversity, and enhance crop productivity. Arbuscular mycorrhizal fungi (AMF) are key soil symbionts that facilitate nutrient acquisition and enhance stress resilience in host ...

Geobacillus and Bacillus Spore Inactivation by Low Energy Electron Beam Technology: Resistance and Influencing Factors

Frontiers in Microbiology, 2018
Low energy electron beam (LEEB) treatment is an emerging non-thermal technology that performs surface decontamination with a minimal influence on food quality. Bacterial spore resistance toward LEEB treatment and its influencing factors were investigated

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.

Bacterial Geosmin Biosynthesis is Compartmentalized Inside a Two‐Component Protein Shell

Advanced Science, EarlyView.
This study reports the discovery that geosmin biosynthesis is compartmentalized inside a two‐component protein shell in many bacteria. Sequestration of geosmin synthase inside a Family 2B encapsulin nanocompartment improves geosmin yield and increases enzyme stability as compared to the free enzyme.

Spore associated bacterial communities display patterns related to the arbuscular mycorrhizal host genotype in Mediterranean sand dunes

Environmental Microbiome
Background Arbuscular mycorrhizal fungi (AMF) are beneficial microorganisms establishing symbioses with the roots of most plants, supporting their nutrition and health, mainly in nutrient-poor and harsh environments.

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.

Bacillus Licheniformis‐Induced Cognitive Decline in Mice Linking Gut Microbiota Dysbiosis, Metabolic Perturbations, and Hippocampal Neuroinflammation

Advanced Science, EarlyView.
Chronic oral administration of specific probiotic strains triggers gut microbiota dysbiosis and systemic metabolic perturbations in mice. Multi‐omics profiling reveals subsequent hippocampal glial remodeling and neuroinflammation, which are linked to cognitive impairment.

Antagonistic activity of bacterial spore former probiotics in respect to mycobacteria species and susceptibility changing to antibiotics

RUDN Journal of Medicine, 2010
Studies on antagonistic activity of three bacterial spore former probiotics in respect to mycobacteria species were conducted. The influence of spore probiotics on a susceptibility to antibiotics were examinated.
