Isolation and Characterization of Superdormant Spores of Bacillus Species
Sonali Ghosh,Peter Setlow +1 more
TL;DR: It is suggested that superdormant spores require an increased signal for triggering spore germination compared to most spores in populations, and a second important factor may be heat activation of spore populations, since yields of superdorman spores from non-heat-activated spores populations were higher than those from optimally activated spores.

The preparation, germination properties and stability of superdormant spores of Bacillus cereus.
Sonali Ghosh,Peter Setlow +1 more
TL;DR: The objective is to determine yields, germination and stability of superdormant Bacillus cereus spores and to establish a phytochemical profile that can be used as a guide for selecting new Bacillus species for cultivation.

Superdormant Spores of Bacillus Species Germinate Normally with High Pressure, Peptidoglycan Fragments, and Bryostatin
TL;DR: Superdormant spores of Bacillus cereus and Bacillus subtilis germinated just as well as dormant spores with pressures of 150 or 500 MPa and with or without heat activation.

Function of the SpoVAEa and SpoVAF Proteins of Bacillus subtilis Spores
Abigail Perez-Valdespino,Yunfeng Li,Barbara Setlow,Sonali Ghosh,David Pan,George Korza,Florence E. Feeherry,Christopher J. Doona,Yong-qing Li,Bing Hao,Peter Setlow +10 more
TL;DR: The Bacillus subtilis spoVAEa and spoVAF genes are expressed in developing spores as members of the spoVA operon, which encodes proteins essential for the uptake and release of dipicolinic acid during spore formation and germination.

Analysis of killing of growing cells and dormant and germinated spores of Bacillus species by black silicon nanopillars.
Sonali Ghosh,Shanyuan Niu,Maya Yankova,Matthew Mecklenburg,Stephen M. King,Jayakanth Ravichandran,Rajiv K. Kalia,Aiichiro Nakano,Priya Vashishta,Peter Setlow +9 more
TL;DR: The cidal activity of bSi on growing cells, dormant and germinated spores of B. subtilis, and dormant spores of several other Bacillus species is reexamined by incubation on bSi wafers with and without nanopillars to elucidating the limits of mechanical bactericidal approaches.
