At least 24 randomly chosen squares with about 100 cells were counted. Suspensions were diluted to an appropriate spore density of about 10 8 spores mL −1. For volume determination, the shape of the endospores was approximated as a cylinder with ... The spore suspension is generated by treating fecal matt

The formation of bacterial spores (sporulation) is a common and well-characterized survival strategy in many microbial species (1, 2).Spores are partially dehydrated cells enclosed by a protective coat that can survive environmental extremes and remain dormant for years ().They need to be robust to environmental fluctuations to avoid …For the Equation (1) counts, the category “≥3 spores” was the sum of particles meeting the criteria for three- and four-spore clusters.
