Observations of an extreme form of late eccentric lytic fission in Schizosaccharomyces pombe

Late eccentric lytic fission was initially observed in Schizosaccharomyces pombe in 1967 (Johnson, B.F. (1967) J. Bacteriol. 94, 192–195). We report here an extreme form of this morphology and have studied the incidence of severity with respect to glucose concentration of the growth media. Alterations to the composition of the growth medium were made to allow cells to reach a density of 1 × 108 cells ml−1 before lysis occurred.
