Impact of Fire and Heat Stress on Soil Microorganisms: A Review of Community Changes, Molecular Responses and Plant‐Beneficial Roles

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This work reviewed the direct and indirect effects of fires on microbial communities and the resilience strategies microbes use to withstand high temperatures . ABSTRACT Fire, whether occurring on the surface or underground, significantly influences soil microbial dynamics by reshaping community composition, functional diversity and overall soil and ...

A Genomic Signature and the Identification of New Sporulation Genes [PDF]

open access: yes, 2013
Bacterial endospores are the most resistant cell type known to humans, as they are able to withstand extremes of temperature, pressure, chemical injury, and time.

Differential Analysis of IAA Anabolism Pathway Based on Bacillus cereus, Bacillus subtilis and Bacillus safensis Genome

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Three Bacillus species isolated from Platycladus orientalis rhizosphere in Taihang Mountains: Bacillus cereus has 3 IAA synthesis pathways (TAM, IAM, IPyA); Bacillus subtilis has IAM/IPyA; and Bacillus safensis only has IPyA (via whole‐genome sequencing).

Specificity of the AMP-6000 Method for Enumerating Clostridium Endospores in Milk

open access: yesFoods
Enumeration of endospores of butyric acid-forming clostridia in cheese milk is an essential part of milk quality monitoring for cheese producers to avoid late blowing, severe spoilage caused by clostridia during ripening.

Transcriptional analysis of temporal gene expression in germinating Clostridium difficile 630 endospores. [PDF]

open access: yes, 2013
Clostridium difficile is the leading cause of hospital acquired diarrhoea in industrialised countries. Under conditions that are not favourable for growth, the pathogen produces metabolically dormant endospores via asymmetric cell division.

Mechanism and Molecular Design Principles of Cationic Surfactants: From Charge‐Driven Membrane Interactions to Next‐Generation Quaternary Ammonium Compounds

open access: yesChemMedChem, Volume 21, Issue 5, 13 March 2026.
Within this review we provide an overview of the social relevance of quaternary ammonium surfactants, different classes of these agents, their interaction mechanism with cellular membranes, structure activity relation, bacterial resistance toward these systems and new approaches to guarantee their long‐term efficiency.

Hyperspectral Reflectance for Rapid Viability Assessment of Bacillus Endospores [PDF]

open access: yes, 2009
A study was conducted to optically determine the viability of the Gram +, endospore-forming bacterial genera Bacillus using a hyperspectral reflectance spectrometer. Endospores are a dormant, differentiated cellular capsule form taken by select bacteria
