The cell cysteic acid content began to increase at the onset of sporulation and was maximal when synthesis of dipicolinic acid commenced; it then decreased as sporulation advanced. Cysteic acid was synthesized from cysteine and metabolized to sulpholactate in the mother-cell cytoplasm, and the sulpholactate was then incorporated into the forespore. This metabolic change is considered to be a general phenomenon in spore-formers that contain sulpholactate in their spores., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-124-2-415
