Spore Coat Architecture of Clostridium novyi NT Spores [PDF]

Journal of Bacteriology, 2007
ABSTRACT Spores of the anaerobic bacterium Clostridium novyi NT are able to germinate in and destroy hypoxic regions of tumors in experimental animals. Future progress in this area will benefit from a better understanding of the germination and outgrowth processes that are essential for the tumorilytic ...

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

Advanced Science, EarlyView.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Characterization of Putative Sporulation and Germination Genes in Clostridium perfringens Food-Poisoning Strain SM101

Microorganisms, 2022
Bacterial sporulation and spore germination are two intriguing processes that involve the expression of many genes coherently. Phylogenetic analyses revealed gene conservation among spore-forming Firmicutes, especially in Bacilli and Clostridia.

Extraction of Spore-lytic Enzyme from Clostridium perfringens Spores [PDF]

Microbiology, 1981
Various chemical reagents known to extract spore coat protein were used to extract spore-lytic enzyme (SLE) from intact and germinated spores of Clostridium perfringens. Of the reagents tested, 7.2 M-urea plus 10% (v/v) mercaptoethanol, pH 2.85, solubilized the most SLE activity per mg spores.

Characterization of Clostridium difficile Spores Lacking Either SpoVAC or Dipicolinic Acid Synthetase

Journal of Bacteriology, 2016
The spore-forming obligate anaerobe Clostridium difficile is a leading cause of antibiotic-associated diarrhea around the world. In order for C. difficile to cause infection, its metabolically dormant spores must germinate in the gastrointestinal tract ...

Plant Robotics for Sustainable and Environmentally Friendly Robots: Insights from Actuation Characteristics

Advanced Science, EarlyView.
Plants are promising materials for building sustainable and eco‐friendly robots due to their inherent multifunctionality, with actuation playing a crucial role. This article focuses on the physical movements of plants and, from the perspective of actuation characteristics, explores representative plant species and their behaviors, the current state of ...
