Neosartorya clavata

Ciri dan struktur

Aspergillus clavatus undergoes rapid growth, resulting in the formation of a velvety and fairly dense felt that is observed to be bluish-grey green in colour. The emerging conidial heads are large and clavate when very young, quickly splitting into conspicuous and compact divergent columns. The conidia bearing conidiophores are generally coarse, smooth walled, uncoloured, hyaline and can grow to be very long. Elongated club-shaped vesicles clavate, and bear phialides (singular: phialide) over their entire-surface, contributing to its short and densely packed structure. The sterigmata are usually found to be uniseriate, numerous and crowded. Conidia formed in them are elliptical, smooth and comparatively thick-walled. A. clavatus usually express conidiophores 1.5–3.00 mm in length, which arises from specialized and widened hyphal cells that eventually become the branching foot cells. The conidia on A. clavatus has been measured up to 3.0 – 4.5 X 2.5 – 3.5 μm. Cleistothecia are produced in crosses after approximately 4–10 weeks of incubation on suitable growth media at 25 °C. Cleistothecia are yellowish-brown (fawn) to dark brown in colour and range in diameter from 315-700 μm in diameter and have a relatively hard outer wall (peridium). At maturity the cleistothecia contain asci that themselves contain ascospores, which are clear, lenticular (with ridges evident) and between 6.0-7.0 μm in diameter.

Habitat dan peran ekologis

Aspergillus clavatus is often described as a spoilage organism occurring on dung and in soil and can also grow in strong alkaline conditions. When it comes to geographical distribution, A. clavatus has been spotted in the tropical, subtropical and Mediterranean areas. It has been accounted in low frequencies in the soils of India. And is also found in Bangladesh, Sri Lanka, Hong Kong, Jamaica, Brazil, Argentina, South Africa, the Ivory Coast, Egypt, Libya, Turkey, Greece, Italy, the United States of America, Japan, the USSR and Czechoslovakia. It was tracked in rocks of a carst cave and stratigraphic core samples descending to 1200 m in Central Japan. However, it is usually and solely collected from cultivated soils, including the ones that bear cotton, potatoes, sugar canes, legumes, paddy and Artemisia herba-alba. It has also been garnered from soil under burnt steppe vegetation, desert soils, the rhizospheres of banana, ground-nuts and wheat. A. clavatus has also been detected in the ripe compost of municipal waste, and Nitrogen and NPK fertilizers are found to play an important role in its stimulation process. A. clavatus is also referred as a cosmopolitan fungus. Other than soil and dung, it can additionally be found in stored products with high levels of entrapped moisture.
