Cladosporium sphaerospermum

Ciri dan struktur

The hyphae of Cladosporium sphaerospermum are thick walled, septate, and olivaceous-brown in colour. Colonies of the fungus are velvety in texture and flattened (i.e., rarely raised, fluffy, or radially furrowed). C. sphaerospermum conidiophores are branched, septate, and dark, up to 150–300 μm long and 3.5–4.0 μm wide. The structure of the conidiophores are tree-like, a prominent feature of the genus Cladosporium. Unlike other related species, the conidiophores of this species lack swollen nodes at the branching points. Conidia of this species are characteristically globose to ellipsoid with a diameter of 3.4–4.0 μm. The conidia are formed in branching chains in which the youngest conidium is situated at the top. Cladosporium sphaerospermum also produces ramoconidia 6–14 × 3.5–4.0 μm in length and this feature can be used as a method of distinguishing between similar species. Ramoconidia are conidia found at the branching points joining multiple spore chains and can be recognized by one end having a single attachment scar and the other end having two or more attachment scars. Cladosporium sphaerospermum is also a psychrophilic fungus, known to grow at temperatures as low as -5 C with an upper limit of 35 C and no growth at 37 C. The optimal temperature this fungus grows under is 25 C. This fungus is xerotolerant as it can thrive in environments with low water activity caused by high salinity (halotolerant) or other dissolved solutes. This fungus has been observed to grow in as low as 0.815 aw (water activity) in vitro.

Habitat dan peran ekologis

Cladosporium sphaerospermum is a cosmopolitan fungus that inhabits city buildings and the environment and because of its airborne nature it can move rapidly between locations, though the extent of this is lacking in research. It is found in hypersaline environments in Mediterranean and tropical climates, as well as soil and plant environments in temperate climates. The indoor presence of this fungus can signify there is a condensation problem within the building such as on bathroom walls and in kitchens. Cladosporium sphaerospermum has also been shown to inhabit paint films on walls and other surfaces as well as old paintings. This fungus is also able to grow on gypsum-based material with and without paint and wallpaper. Plant materials that are affected include citrus leaves and various other decaying plant leaves, on the stems of herbaceous and woody plants, on fruits and vegetables. The fungus has also been reported from wheat-based bakery items.
