Brewing microbiology – bacteria of the genus Clostridium

Kvasný průmysl, 2018
In most cases, the Clostridium species rank among the sporogenic obligate anaerobes, which are sensitive to bitter hop substances and acidic pH. Thus they rank among the less dangerous contaminants in brewing operations.

Protocol for quantifying the germination properties of individual bacterial endospores using PySpore

STAR Protocols, 2023
Summary: PySpore is a Python program that tracks the germination of individual bacterial endospores. Here, we present a protocol for segmenting spores and quantifying the germination properties of individual bacterial endospores using PySpore.

Multiple roads lead to Rome: unique morphology and chemistry of endospores, exospores, myxospores, cysts and akinetes in bacteria. [PDF]

, 2023
The production of specialized resting cells is a remarkable survival strategy developed by many organisms to withstand unfavourable environmental factors such as nutrient depletion or other changes in abiotic and/or biotic conditions. Five bacterial taxa

Pressure Inactivation of Bacillus Endospores [PDF]

Applied and Environmental Microbiology, 2004
ABSTRACT The inactivation of bacterial endospores by hydrostatic pressure requires the combined application of heat and pressure. We have determined the resistance of spores of 14 food isolates and 5 laboratory strains of Bacillus subtilis , B. amyloliquefaciens , and B.

Surface Layers of Clostridium difficile Endospores [PDF]

Journal of Bacteriology, 2011
ABSTRACT Clostridium difficile is an important human pathogen and one where the primary cause of disease is due to the transmission of spores. We have investigated the proteins found in the outer coat layers of C. difficile spores of pathogenic strain 630 (CD630). Five coat proteins, CotA, CotB,

Multi-Functional Silver Nanoparticles for High-Throughput Endospore Sensing

Biosensors, 2022
In spore-forming bacteria such as Bacillus and Clostridium, the vegetative cells form highly durable hard shells called endospores inside the bacteria to survive as the growth environment deteriorates.

Effects of nisin and reutericyclin on resistance of endospores of Clostridium spp. to heat and high pressure

, 2013
The effects of high pressure, temperature, and antimicrobial compounds on endospores of Clostridium spp. were examined. Minimal inhibitory concentrations (MIC) of nisin and reutericyclin were determined for vegetative cells and endospores of Clostridium ...

Copper-tripeptide complexes for rapid inactivation of Bacillus subtilis endospores

Biotechnology Notes
Bacterial endospores can be pathogenic to human beings. However, they are robust and thus difficult to kill due to their rigid structure. Conventional methods such as autoclaving for inactivating endospores are energy-intensive and time-consuming.
