Application
Bacterial spore germinant research
Bacterial spores are more resistant to antibiotics and nutritional deficiencies than their vegetative cells and sometimes cause serious problems from the viewpoint of hygiene in clinical treatment and food processing.1) Spore persistence also plays a major role in the recurrence of infections after antibiotic treatment. Molecules that stimulate germination are termed “germinants”1) and the efficacy of germinant administration combined with antibiotics have been evaluated (for example, reports by N. Budi et al.2,3)). L-Lactic acid has been reported to stimulate germination in Clostridia.4-7)
