    Fission yeast is a single-celled fungus that divides across the middle rather than producing the unequal buds familiar in brewer's yeast. It is an important model for chromosome biology and the control of the eukaryotic cell cycle.

    Structure and identification

    Cells are elongated, often with rounded ends. A dividing cell forms a transverse partition near its middle.

    Scientific source 1 ↗ · Scientific source 2 ↗

    Habitat and range

    The species has been recovered from fermentation-associated materials and is maintained on defined laboratory substrates.

    Scientific source 1 ↗ · Scientific source 2 ↗

    Nutrition and metabolism

    Organic nutrients, including sugars, support growth. Carbon source and nutrient availability influence physiology.

    Biological activity

    Cells extend at their tips and coordinate growth with nuclear division and septum formation.

    Reproduction and life cycle

    Vegetative cells reproduce by fission. Mating and meiosis under suitable conditions lead to spore formation.

    Geographic distribution

    Research and fermentation records occur in different regions, but these should not be treated as a complete map of natural populations.

    Ecological role

    The fungus forms part of microbial communities associated with organic substrates and fermentation.
