Bacillus anthracis and Bacillus subtilis spore surface properties and transport

Impeding <i>Bacillus</i> spore germination <i>in vitro</i> and in milk by soy glycinin during long cold storage

“…The anti-hemolytic action of glycinin or BS against the spores of the hemolytic strain (B. licheniformis) may have occurred through their adhesion on the negatively-charged spore out-surfaces (Chen et al, 2010) impeding their germination and, thus, their hemolytic activity. Both glycinin and BS have positive charges based on their relatively higher iso-electric points (ca.…”

“…Additionally, B. licheniformis has also been associated with septicemia, peritonitis, ophthalmitis, and dairy product poisoning in humans (Frank, 1997;Turnbull and Kramer, 1995). Being protected by their sophisticated cortex structure, the decontamination of Bacillus spores remains a significant challenge (Chen et al, 2010;Driks, 1999). Nevertheless, the strong negative charges on the surface of Bacillus spp.…”

Neutralization of Bacterial Aerosols by Aerodynamic Shocks in a Novel Impactor System: An Integrated Computational and Experimental Study

“…The two spores have similar surface tension values [8]. Both computational and experimental methods are used to study the effect of aerodynamic shocks on B. atropheus spores and to obtain the fraction of cells that remain alive after the effect of impactor operation (/;).…”

“…Oh is the Ohnesorge number, which is the ratio between the viscous forces and the surface tension force. Table 5.3 are derived from the turgor pressure [61] and contact angle [8].…”

“…A high Mach number drag law is used to calculate the drag coefficient {Co) [9]. The size of Bacillus spores is in the range of 0.5 -1.2 /xra [10,8]. The bacterium is simulated as a 0.5 p,m sphere with a density p p of lg/mL which is representative of values reported in literature [33,59].…”
