Growth and sporulation of entrapped Bacillus subtilis cells.
Growing Bacillus subtilis cells were immobilized in k-carrageenan gel beads. Growth and sporulation of entrapped cells were studied by two different methods: cell enumeration and transmission electron microscopy. Immobilized growing cells had a shorter generation time than free cells did, whereas sporulation timing was unchanged. When steady state was reached, cell density was very high in gel beads.
