    Structure and identification

    Cells are rod-shaped. Microscopic appearance alone cannot distinguish this species securely from related lactic acid bacteria.

    Scientific source 1 ↗ · Scientific source 2 ↗ · Scientific source 3 ↗

    Habitat and range

    The species has been studied in fermented foods and host-associated settings. Survival and growth differ among strains and substrates.

    Nutrition and metabolism

    Carbohydrate metabolism produces lactic acid. A strain's ability to use particular sugars requires its own evidence.

    Biological activity

    Growth and stress responses change with the chemical environment. Studies of GG in yogurt concern that strain and tested conditions.

    Reproduction and life cycle

    Cells reproduce through division. The name GG denotes an inherited strain identity, not a reproductive stage.

    Geographic distribution

    Food and research cultures are distributed widely. The origin and identity of an isolate should accompany an occurrence record.

    Ecological role

    Fermentation and host-associated microbial communities provide contrasting settings for interactions with other organisms.

    Distinctive adaptations

    Differences in adhesion, metabolism and stress tolerance can distinguish strains within the same species.
