Microcycle conidiation by regenerating protoplasts of Aspergillus awamori

Experimental Mycology, 1982
Abstract Enzymatically prepared protoplasts of Aspergillus awamori regenerate cell walls and become resistant to osmotic shock within 4 hours after their removal from the digestion mixture. By 6 hours, germ tubes have been formed by many of the reverting protoplasts.

Microcycle conidiation in Penicillium urticae: an ultrastructural investigation of conidiogenesis

Canadian Journal of Microbiology, 1975
A cultivation system has been developed for Penicillium urticae 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 results in synchronous germination and limited outgrowth followed ...

Effect of metabolic inhibitors on microcycle conidiation of Aspergillus niger

Transactions of the British Mycological Society, 1979
The effects of several metabolic inhibitors on normal spore germination and microcycle conidiation in Aspergillus niger van Teigh. were examined. Normal spore germination showed the greatest susceptibility to inhibition, followed by conidiation, while giant cell formation (vegetative growth) was the least susceptible.

Microcycle conidiation in the entomopathogenic fungus Beauveria bassiana bals. (vuill.)

Process Biochemistry, 1999
Abstract The present work documents the experimental conditions under which the three types of two local strains of Beauveria bassiana conidia enter into a microcycle conidiation process (conidiation without vegetative phase). Different levels of different C (glucose and starch) and N sources (KNO3, NH4Cl, glutamate and peptone) were added to a basal

Spore Germination and Microcycle Conidiation of Two Penicillia in Soil

Mycologia, 1984
Laboratory-produced spores of two penicillia isolated from soil were placed onto PVC membrane filters, inserted into microholders and buried in the A horizon of an oak-birch forest. After various intervals of time incubation filters were retrieved, stained, and mounted on glass slides for examination.

Dimorphism and microcycle conidiation of Pseudocercospora pseudostigmina‐platani conidia from American sycamore

Forest Pathology, 2022
Abstract In this study, the micromorphology and surface details of Pseudocercospora pseudostigmina‐platani conidia were investigated on American sycamore ( Platanus occidentalis ) leaves. Sooty films were collected from diseased leaves

Effect of medium composition on microcycle conidiation in Aspergillus niger

Transactions of the British Mycological Society, 1986
The effect of the physical and chemical environment on microcycle conidiation in A. niger has been studied in a 5 1 fermenter. It appears that temperature is the critical factor for giant-cell formation and germ-tube suppression, the addition of CO2 having little effect.

DNA, RNA and protein biosynthesis during microcycle conidiation in Aspergillus niger

Transactions of the British Mycological Society, 1978
The levels of DNA, RNA and protein were determined at different stages throughout microcycle conidiation in Aspergillus niger van Tiegh. The period of maximum accumulation of these cellular components occurred during spore growth rather than the period of conidiophore outgrowth.

Mmc, a gene involved in microcycle conidiation of the entomopathogenic fungus Metarhizium anisopliae

Journal of Invertebrate Pathology, 2010
Microcycle conidiation is a survival mechanism for some fungi encountering unfavorable conditions, in which asexual spores germinate secondary spores directly without formation of mycelium. Here, we isolated a microcycle conidiation associated gene, Mmc, from Metarhizium anisopliae and obtained its full length of cDNA and DNA sequence.

Production of conidia of Penicillium camemberti in liquid medium through microcycles of conidiation

Biotechnology Letters, 2014
Microcycle conidiation is a survival mechanism of fungi encountering unfavorable conditions. In this phenomenon, asexual spores germinate secondary spores directly without formation of mycelium. As Penicillium camemberti conidia have the ability to produce conidiophores after germination in liquid culture induced by a thermal stress (18 and 30 °C), our
