Recently, one of the Journal of Bacteriology Classic Spotlight series highlighted the numerous studies on bacterial spores that have been published in the journal throughout the years. Bacterial endospores, the resilient and relatively quiescent bacterial structures first identified in the 1800s, have had their genetic regulation, immunological properties, and biochemical makeup investigated for decades. The structures are incredibly resistant and produced by select members of the Gram-positive Firmicutes phylum. Despite many rigorous studies investigating these biological structures, new research published in Applied and Environmental Microbiology shows that there’s always something new to learn in microbiology, including aspects that appear as straightforward as morphology.
