Surface charge and hydrodynamic coefficient measurements of {\it Bacillus subtilis} spore by Optical Tweezers [PDF]

Colloids and Surfaces B: Biointerfaces Volume 116, 1 April 2014, Pages 568-575, 2014
In this work we report on the simultaneous measurement of the hydrodynamic coefficient and the electric charge of single {\it Bacillus subtilis} spores. The latter has great importance in protein binding to spores and in the adhesion of spores onto surfaces. The charge and the hydrodynamic coefficient were measured by an accurate procedure based on the

Separation of bacterial spores from flowing water in macro-scale cavities by ultrasonic standing waves [PDF]

, 2010
The separation of micron-sized bacterial spores (Bacillus cereus) from a steady flow of water through the use of ultrasonic standing waves is demonstrated. An ultrasonic resonator with cross-section of 0.0254 m x 0.0254 m has been designed with a flow inlet and outlet for a water stream that ensures laminar flow conditions into and out of the resonator

Effects of Aqua-Glycerol Uptake Facilitator Protein GlpF on Spore Germination of Bacillus subtilis [PDF]

Foods
Killing spores is an important challenge for the development of the food industry. After germination, the resistance of spores disappears and they are more easily killed, which is currently the main strategy for their destruction. Therefore, study of the

Probiotic spore-based antigen delivery: a novel oral vaccine strategy against Vibrio infections in aquaculture [PDF]

Microbial Cell Factories
Background Vibriosis is a deadly illness caused by various species of the Vibrio genus. Due to its high incidence in aquaculture plants, vibriosis is responsible for significant economic losses.

FAST CARS: Engineering a Laser Spectroscopic Technique for Rapid Identification of Bacterial Spores [PDF]

arXiv, 2002
Airborne contaminants, e.g., bacterial spores, are usually analyzed by time consuming microscopic, chemical and biological assays. Current research into real time laser spectroscopic detectors of such contaminants is based on e.g. resonant Raman spectroscopy. The present approach derives from recent experiments in which atoms and molecules are prepared

Emerging Applications of Bacterial Spores in Nanobiotechnology [PDF]

Journal of Nanobiotechnology, 2003
Bacterial spores are robust and dormant life forms with formidable resistance properties, in part, attributable to the multiple layers of protein that encase the spore in a protective and flexible shield.

Oral vaccination of fish against vibriosis using spore-display technology

Frontiers in Immunology, 2022
Oral vaccines are highly demanded by the aquaculture sector, to allow mass delivery of antigens without using the expensive and labor-intensive injectable vaccines. These later require individual handling of fish, provoking stress-related mortalities.One

Research Progress on Formation, Germination and Control Methods of Bacterial Spores

Shipin gongye ke-ji, 2023
Bacterial spores are extremely resistant to various processing techniques attributable to its special structure and physiological processes, and often lead to the spoilage of thermally sterilized food. Therefore, it is of great significance to inactivate
