Chaetomium globosum

Ciri dan struktur

Chaetomium globosum is a well-known mesophilic member of the mold family Chaetomiaceae. It is a saprophytic fungus that primarily resides on plants, soil, straw, and dung. Endophytic C. globosum assists in cellulose decomposition of plant cells. They are found in habitats ranging from forest plants to mountain soils across various biomes. C. globosum colonies can also be found indoors and on wooden products. Like most Chaetomium species, C. globosum decomposes plant cells using hyphal cellulase activity. Even though they are known to cause soft rot rather than brown rot, C. globosum plant decomposition leaves behind lignin residues. They can decay a variety of wood types such as aspen and pine and even change the colour of paper and books. The cellulase activity of C. globosum functions best at temperatures ranging from 25-32 degrees Celsius and is stimulated by nitrogen and biotin. Cellulase is inhibited by ethyl malonate. Like many fungal species, C. globosum obtains their energy from carbon sources such as glucose, mannitol and fructose. Fructose is usually digested outside the hyphae using fructokinase activity, whereas glucose enters the cell undigested for cellular metabolism. Even though glucose is the most preferred carbon source, C. globosum mycelium growth occurs at a higher rate when treated with acetate rather than glucose. Carbohydrates can also be stored within the fungus as glycogen and trehalose energy reserves. Homothallic C.globosum sexual sporulation produces flat lemon-shaped ascospores within clavate ascomata. The appearance of C.globosum fruiting bodies are similar to the pycnidia of the genus Pyrenochaeta.

Reproduksi

Homothallic C.globosum sexual sporulation produces flat lemon-shaped ascospores within clavate ascomata. The appearance of C.globosum fruiting bodies are similar to the pycnidia of the genus Pyrenochaeta. The ascomata optimally fructify at temperatures ranging from 18-20 degrees Celsius and develop asci with 8 ascospores each. Additional conditions such as neutral pH, mild levels of carbon dioxide, the presence of calcium ions, and soluble sugar media also assist in the development of fruiting bodies. The soluble sugar media consists of glucose, maltose, sucrose, and cellulose. Sporulation preferably occurs in the dark and at high temperatures around 26 degrees Celsius. The presence of cellulose is also crucial for sporulation.
