Immobilization of bacterial spores using eggshells nanoparticles and their effective role in concrete bio-healing process: novel approach [PDF]

BMC Biotechnology
Background Microbially induced calcium carbonate precipitation (MICP) has gained increasing attention as a sustainable bioengineering strategy for improving the strength and bio-healing capacity of concrete. Through biologically mediated CaCO₃ formation,

Toxicity study of SARS-CoV-2 Spike protein expressed on Bacillus subtilis spores [PDF]

BMC Microbiology
Background The SARS-CoV-2 spike protein is the primary antigen used in most COVID-19 vaccines. To improve protection, especially at mucosal surfaces, a robust and safe delivery system capable of inducing both systemic and mucosal immunity is needed ...

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

Comparison of Synergistic Effect of Nisin and Monolaurin on the Inactivation of Three Heat Resistant Spores Studied by Design of Experiments in Milk

Journal of Food Quality, 2021
Spore forming bacteria are special problems for the dairy industry. Heat treatments are insufficient to kill the spores. This is a continuously increasing problem for the industry, but we should be able to control it. In this context, we investigated the
