Development of Bacillus subtilis spores and cells for surface display of proteins
… bacterial and eukaryotic cells and bacterial spores. Among these bioparticles, the endospore from B. subtilis has advantages, including feasibility of production, safety feature, the robustness of the bacterial spore allowing storage in the desiccated form, a technological platform supported …

Investigating proteins that influence membrane-associated germination processes in Bacillus subtilis spores
… diseases such as anthrax and food poisoning. Spores however also contribute to various agricultural and industrial processes. Spores possess extreme resistance properties, notably to chemical, et and dry heat, desiccation, and UV damage. For pathogenic spore formers, this poses an issue as …

A Comparative Study of Synergistic Effects in Sequential Inactivation of Cryptosporidium Parvum Oocysts and Bacillus Subtilis Spores With Chemical Disinfectants
… compositions of C. parvum oocysts and Bacillus subtilis spores, this study put special emphasis on utilizing B. subtilis spores as a second, well-characterized microorganism, in order to develop explanations about the mechanism of inactivation of the C. parvum oocysts that were …

Use of Direct-Fed Microbes To Enhance Shrimp Resistance to a Vibrio Parahaemolyticus Strain Causing Early Mortality Syndrome
… hypothesis that probiotics (specific strains of Bacillus subtilis spores) are able to provide shrimp, Litopenaeus vannamei, protection to the EMS disease, a pathogen growth model, disease challenge model, and probiotic feed coating methodologies were developed and refined, allowing independent …

The Influence of Prebiotics, Probiotics, and Exposure to an Opportunistic Pathogen on the Intestinal Microbiome of White Shrimp (Litopenaeus vannamei)
… vannamei). A monoculture probiotic strain of Bacillus subtilis spores: O14VRQ, and a prebiotic product of cultured Saccharomyces cerevisiae cell walls: MOS, were administered to shrimp as feed additives for 14 days, before a pathogen challenge to VP-EMS. Based on previous efforts, animals in …

High hydrostatic pressure inactivation of Bacillus subtilis var. niger spores : the influence of the pressure build-up rate on the inactivation
… pressure-temperature inactivation kinetics of Bacillus subtilis var. niger spores was first studied under isobaric-isothermal conditions in the pressure range 50�400 MPa at temperatures between 25�70°C. Isobaric-isothermal inactivation of spores appears to follow a fairly linear trend and can …

DISINFECTION USING A NOVEL HETEROGENEOUS CATALYST
… with PCat showed sporicidal activity against Bacillus subtilis spores at 2hrs at room temperature, whereas without the catalyst sporicidal activity was absent. In the presence of H2O2, leachate from PCat was found to contain very low amounts of iron which exhibited potent antimicrobial …

Anharmonic Acoustic Technique for Detection of Surface-bound Particles
… technique (ADT). A feasibility study with Bacillus subtilis spores in phosphate buffer saline (PBS) is carried out successfully where the modeling and experimental results with SCPM are successfully reproduced. A detection limit of 430 spores is demonstrated, which corresponds to a mass …

Investigating the Roles of CwlD and GerS in <i>Clostridioides difficile</i> Spore Cortex Modification
… distinguished by its capacity to produce spores, essential for its survival and dissemination. The spore cortex, consisting of a modified peptidoglycan layer, is essential for dormancy and germination. This work examines the enzyme CwlD, which facilitates the transformation of …
