We administered Acetobacter malorum NCI1683 (S24), containing a high concentration of dihydroceramide (7.2 mg/g of dry cell weight), consecutively to aged rats (male Crlj:Wistar rats, 22 months old). The ingestion of Acetobacter malorum for 89 d significantly extended the memory retention in passive avoidance tests, increased the release of acetylcholine with depolarization of brain synaptosomes and decreased the causative agents of neurodegenerative diseases in the cerebral cortices.
