Fungi mycelial

Fig. 9.2 Changes in the luminescence intensity, the contents of luciferin and SOD, and medium pH during the mycelial growth of five kinds of bioluminescent fungi Panellus stipticus, Armillaria mellea, Mycena citricolor, Pleurotus japonicus, and Omphelotus olearius. The ordinate readings of the curves marked 1/3 should be multiplied by 3. For the SOD activity, see Table 9.2, footnote e. From Shimomura, 1992, with permission from Oxford University Press.

Like fungi, however, actinomycetes display extensive mycelial branching, and both types of microorganisms form aerial mycelia and conidia. Moreover, growth of actinomycetes in liquid culture tends to produce fungus-like clumps or pellets rather than the turbidity produced by bacteria. Finally, growth rates in fungi and actinomycetes are not exponential as they are in bacteria rather, they are cubic [35,42]. 

Mechanism of Action An antifungal that distorts hyphae and stunts mycelial growth in susceptible fungi. Therapeutic Effect Results in fungal cell death. 

Mycelial growth is more sensitive to cymoxanil than early growth phases, including the release of zoospores from sporangia and their germination. Cymoxanil inhibits nucleic acid and protein synthesis in some fungi but may have to be activated to induce a fungicidal response. 

Many other fungi contain alkali-soluble, (1— 3)-linked a-D-gluco-pyranans these are summarized in Table I. In Histoplasma capsula-tum, the cell wall contains a glucan, whereas the mycelial form con-...
