Ciri dan struktur

Pseudallescheria boydii is a saprotrophic fungus with broad hyphae growing up to 2–5 μm in width. Colonies change in colour from white to pale brown and develop a cottony texture with maturity. After a 2–3 week incubation period, cleistothecia may form containing asci filled with eight fusiform, one-celled ascospores measuring 12–18 × 9–13 μm in diameter. This fungus grows on most standard media, maturing in 7 days. Its primary nutrients are the sugars xylose, arabinose, glucose, sucrose, ribitol, xylitol and L-arabinitol. It cannot assimilate maltose or lactose; however, it is able to assimilate urea, asparagine, potassium nitrate and ammonium nitrate. The optimal temperature for growth is 25 C and the fungus is generally considered to be mesophilic, although it can grow at higher temperatures (up to 37 C) as well. Asexual reproduction manifests in one of two forms: the Scedosporium type (the most common type) and the Graphium type. Scedosporium apiospermum forms greyish-white colonies with a grey-black reverse. The conidia are single-celled, pale brown and oval in form. Their size ranges from 4–9 x 6–10 μm and their development is annellidic. Detection and diagnosis of S. apiospermum is possible through isolation of the fungus in culture or through cytology and histopathology in the tissues of diseased individuals. In mycetoma-type infections, a confluence of symptoms is necessary for diagnosis, including tumefaction, draining sinuses and extrusion of grains. Furthermore, P. boydii grains and hyphae should be cultured and observed microscopically after staining with H&E, periodic acid–Schiff stain, Tissue Gram or Grocott's methenamine silver stain.

02 / Kehidupan

Habitat dan peran ekologis

An ability untuk mentolerir aerasi minimal dan tekanan osmotik tinggi memungkinkan P. boydii untuk tumbuh di tanah, air dan pupuk tercemar dan stagnasi. Although this fungus is commonly found in temperate climates, it is thermotolerant and can survive in tropical climates and in environments with low oxygen pressure. Growth of P. boydii dapat dilihat di lingkungan di mana senyawa yang mengandung nitrogen umum, biasanya karena polusi manusia. Kemampuan untuk menggunakan gas alam dan senyawa organik volatile lainnya menunjukkan kemampuan untuk bioremediasi.

Ekologi sumber

An ability to tolerate minimal aeration and high osmotic pressure enables P. boydii to grow on soil, polluted and stagnant water and manure. Although this fungus is commonly found in temperate climates, it is thermotolerant and can survive in tropical climates and in environments with low oxygen pressure. Growth of P. boydii can be seen in environments where nitrogen-containing compounds are common, usually due to human pollution. Its ability to use natural gas and other volatile organic compounds suggests a capacity for bioremediation.
