Preserving spore dormancy
… conditions by forming dormant, resistant endospores that later resume growth through germination. Because germination abolishes spore resistance, developing spores must avoid responding to germinants too early. This thesis examines how sporulating bacteria prevent premature germination during …

Characterization of Bacillus Spore Membrane Proteomes and Investigation of Their Roles in the Spore Germination Process
Components of the bacterial spore germination apparatus are crucial for survival and for initiation of infection by some pathogens. While some components of the germination apparatus are well conserved in spore-forming species, such as the spoVA operon, each species may possess a different and …

Morphogenesis of the Bacillus Anthracis Spore
… enzymes, and antimicrobials, the bacterial spore is one of the most-resistant forms of life on earth. Although most spores are harmless, several species' spores cause serious diseases such as tetanus, anthrax, gas gangrene, botulism, and diarrhea. Spore-forming bacteria differentiate into …

Spore-forming bacteria as pharmaceutical factories
Many Bacilli form dormant structures, spores, which routinely survive physical, chemical and biological challenge. How do spores encapsulate their contents, and could it be possible to mimic or adapt them to make better drug products? Key spore component 2,6-dipicolinic acid (DPA) is necessary for …

Understanding the Function of SpoIIIL during Spore Development
… of the SpoIIIA-SpoIIQ (A-Q) complex from the forespore compartment. Here, we report that SpoIIIL is required for spore shape, functions in the monitoring, regulation, and signalling of cortex assembly, ensures the timely activation of sigma G, is not surface exposed, and is unlikely a component of …

Microsporidia Spore Adherence and Host Cell Infection In Vitro
… essential for the development of new therapies. Spores adhere to host cell surfaces<em> in vitro. </em>Our laboratory has focused on determining specific host cell and microsporidia spore surface participants in spore adherence. Our previous studies have shown that host cell sulfated …

Differential Response of Various Spore Species to Sporicidal Disinfectants
… the fall of 2001, letters laced with anthrax spores were delivered to various news organizations in New York and Florida, as well as to two Senators in Washington, D.C. Over 22 anthrax infections and five deaths resulted from exposure to these spores, and decontamination of the affected …

Structural Analysis of Bacillus subtilis Spore Peptidoglycan During Sporulation
Bacterial spore peptidoglycan (PG) is very loosely cross-linked relative to vegetative PG. Theories suggest that loosely cross-linked spore PG may have a flexibility which contributes to the attainment of spore core dehydration. The structure of the PG found in fully dormant spores has previously …

Cultivation of Palmaria palmata: spore release, vegetative propagation and decontamination techniques.
… has been unsuccessful in the past due to poor spore survival, poor attachment to substrates, slow growth and degradation of biomass in tanks. This project aimed to find methods of growing P. palmata from spores and vegetatively for the development of a commercial crop. Initially, methods of …

Protein engineering of cota laccase by using bacillus subtilis spore display
Spore display offers advantages over more commonly utilized microbe cell-surface display systems. For instance, protein-folding problems associated with the expressed recombinant polypeptide crossing membranes are avoided. Hence, a different region of protein space can be explored that previously …

Molecular analysis of GerP and spore-associated proteins of Bacillus cereus
Spores of various strains of Bacillus cereus are the causative agents of emetic and diarrheal foodborne illnesses. Typically, spores will survive thermal treatments that destroy vegetative cells, and then go on to germinate to form the vegetative cells that are associated with toxin production. The …

Characterization of proteins involved in Bacillus subtilis spore formation and germination
… ultimately leading to the formation of an endospore. In some instances, the spore serves as the infectious agent of an associated disease; such is the case with the spore of Bacillus anthracis and the disease anthrax. Spores are resistant to a variety of unfavorable environmental conditions …
