Penicillium sp. under bright field microscopy (10 × 100 magnification) with lactophenol cotton blue stain The thallus ( mycelium ) consists of highly branched networks of multinucleated , usually colourless hyphae , with each pair of cells separated by a septum .
Under the microscope, the mold phase will look like a typical Penicillium, with hyaline, septate and branched hyphae; the conidiophores are located both laterally and terminally. Each conidiophore gives rise to three to five phialides, where chains of lemon-shaped conidia are formed. On the 37 °C plate, the colonies grow as yeasts.
Conidia on conidiophores Chain of conidia of Alternaria Conidiomata of Cypress canker (probably Seiridium cardinale) erupting on a Thuja twig. A conidium (/ k ə ˈ n ɪ d i ə m, k oʊ-/ kə-NID-ee-əm, koh-; pl.: conidia), sometimes termed an asexual chlamydospore or chlamydoconidium (pl.: chlamydoconidia), [1] is an asexual, [2] non-motile spore of a fungus.
(12) Golgi apparatus Hyphae growing on tomato sauce (the pale oblong objects to the side are rice grains) Aspergillus niger Conidia on conidiophores. A hypha (from Ancient Greek ὑφή (huphḗ) 'web'; pl.: hyphae) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. [1]
Penicillium digitatum (/ ˌ p ɛ n ɪ ˈ s ɪ l i əm ˌ d ɪ dʒ ɪ ˈ t eɪ t əm /) is a mesophilic fungus found in the soil of citrus-producing areas. [ 1 ] [ 2 ] [ 3 ] It is a major source of post-harvest decay in fruits and is responsible for the widespread post-harvest disease in Citrus fruit known as green rot or green mould.
Penicillium chrysogenum (formerly known as Penicillium notatum) is a species of fungus in the genus Penicillium. It is common in temperate and subtropical regions and can be found on salted food products, [ 1 ] but it is mostly found in indoor environments, especially in damp or water-damaged buildings. [ 2 ]
The mold Penicillium is used to produce the antibiotic penicillin. Almost half of all members of the phylum Ascomycota form symbiotic associations with algae to form lichens. Others, such as morels (a highly prized edible fungi), form important mycorrhizal relationships with plants, thereby providing enhanced water and nutrient uptake and, in ...
Arthrobotrys oligospora was discovered in Europe in 1850 by Georg Fresenius. [1] [2] A. oligospora is the model organism for interactions between fungi and nematodes. [2]It is the most common nematode-capturing fungus, [3] [4] [5] and most widespread nematode-trapping fungus in nature.
