Conidiation capacity and conidial quality are very important for the production and application of mycopesticides. Most filamentous ascomycetous fungi have two distinct patterns of conidiation. Conidiation through microcycle conidiation proceeds to more rapidly achieve a maximum of conidial yield than normal conidiation and hence is of greater merit ...

Canadian Journal of Microbiology, 1975
A cultivation system has been developed for Penicillium urticae (NRRL 2159A) which yields 'microcycle' conidiation in submerged culture. Spherical growth of spores was initiated by incubation at 37 °C in a growth-favoring medium. Transfer of these enlarged spores to a nitrogen-poor medium at 35 °C resulted in synchronous germination and limited ...

Abstract Conidiation of the entomopathogenic fungus Metarhizium acridum on agar media was investigated. M. acridum CQMa102 exhibits two different conidiation patterns on agar media: normal conidiation in which conidia are formed on extended hyphae and microcycle conidiation in which conidiation occurs directly after conidia germination.

Coniochaeta pulveracea is a dimorphic lignicolous fungus that has mostly been isolated from decaying wood. However, relatively little work was conducted on the conditions for the dimorphic switch or the biological interactions of the fungus in its yeast-like microcyclic growth phase.

Microcycle conidiation induced by partial nitrogen deprivation in Neurospora crassa
Canadian Journal of Microbiology, 1984Premature macroconidiation occurs at the tips of germ tubes elongated as presumptive conidiophores from macroconidia of Neurospora crassa incubated at 37 °C in nitrogen-limited shaken cultures. The use of different nitrogen sources indicated that this differentiation process could be induced by ammonium deprivation.

D-Glucose soluble starch, a novel medium for inducing microcyclic conidiation in Aspergillus
Mycological Research, 1992d -Glucose soluble starch (D-GSS) is a new growth medium for the induction of microcyclic conidiation in Aspergillus . Four different aspergilli, A. niveus, A. tamarii, A. terreus and Aspergillus sp. produced conidiophores, vesicles, sterigmata and conidia within 18–24 h of incubation with no intervening vegetative mycelium.

Changes in both respiratory pathways and mitochondrial structure of Neurospora crassa occurred under conditions of microcycle conidiation. Upon heat-treatment at 46 degrees C, conidia developed a highly cyanide-insensitive, hydroxamate-sensitive respiration associated with morphological alterations in mitochondrial membranes; such changes were time ...

The minimum nutrient requirements for growth of Idriella (= Microdochium ) bolleyi in shaken liquid culture were mineral salts, nitrate nitrogen, glucose and thiamine. Typical batch culture kinetics were displayed in this medium and were assessed by culture turbidity when sodium alginate was used to induce growth by dispersed mycelia. Conidia were

Microcycle conidiation and microniche colonization by aspergilli was observed in-situ on various indoor construction and finishing materials. Microcycle conidiation, direct conidiogenesis from a conidium or spore with minimal intervening hyphal development, for several decades has been considered a survival mechanism during stress for a variety of ...

Microcycle conidiation in pycnidial cirrhii of Phomopsis viticola Sacc. Induced by elemental sulfur
Canadian Journal of Microbiology, 1983On a synthetic medium containing elemental sulfur (SMGS), the growth of Phomopsis viticola Sacc. decreased considerably but pycnidia formation was highly stimulated. Secondary pycnidia, developed from spores in the cirrhii themselves, were observed. Formation of pycnidia directly from spores can be described as a microcycle stage.
