• nanocrystals [178] and Ag NPs [179], respectively, as shown in Figure 5A. Recently, it was found that the spores of bacteria such as Bacillus anthracis on the nanoscale can cause food contamination and contagious diseases [180]. Similarly, a list of autotrophic plants and heterotrophic microbes that help in

• routes, respectively. Their structure, morphology, size and compositions were characterized by SEM, EDX and XRD. The NPs demonstrated strong bactericidal potential against Bacillus anthracis cells and endospores. PS2 killed 92.17% of 4.5 × 104 CFU/mL B. anthracis cells within 1 h at a dose of 1 mg/mL

Its very high lethality (LD50 is 2,500 to

• monomers (not heptamers) will be formed at higher temperatures in the absence of a membrane. Principally, the same behavior, albeit at lower temperatures (T > 40 °C), can be anticipated for the protective antigen part of the anthrax toxin from Bacillus subtilis/Bacillus anthracis, which forms heptameric
