In B. subtilis, the sporulation programme is initiated in response to various extracellular and intracellular signals. The signals are sensed by a phosphorelay system comprising five sensory histidine ...

Historically, bacteria were classified by their ability to retain the Gram stain 1. Following the development of electron microscopy, the actual structure of the bacterial cell envelope became ...

Scientists have long searched for the answer to the question of how bacteria decide to cease normal function and form a spore, which in essence means death for the microbe. Bioengineering researchers ...

Bacteria can generally be divided into two classes: those with just one membrane and those with two. Now researchers have used a powerful imaging technique to find what they believe may be the missing ...

Variations in sporulation patterns were characterized in a single-spore isolate of Pachnocybe ferruginea grown in aerated and non-aerated broth, on agar plates and in aerated water. Conidial ...

“When nutrients are lacking, yeast must stop expending the energy it takes to divide. To survive, they either enter a non-dividing, quiescent state, or they differentiate into spores,” stated Dr.

La sporulation désigne le mécanisme de formation et de libération des spores. Un moyen de reproduction Celle-ci intervient pour un grand nombre d'espèces végétales, bactériennes et de champignons, ...

The discovery sheds light on how certain bacteria -- including strains that cause food poisoning and anthrax -- form spores for survival. Scientists have discovered a protein that enables bacteria to ...

Because natural resources are always limited, the right strategy decides about success in life. This also applies to spore-forming bacteria. Bacillus subtilis can survive unfavourable living ...

Food poisoning is a common, yet unpleasant, illness caused by eating contaminated items. It is sometimes caused by Clostridium perfringens, a pathogen widely found in soil and the intestinal tracts of ...
