Light-independent conidiation in Trichoderma spp.: a novel approach to microcycle conidiation

World Journal of Microbiology & Biotechnology, 1993
Microcycle conidiation in Trichoderma hamatum and T. harzianum has been achieved in complete darkness for the first time. The time required for mass conidiation without intervening vegetative growth was decreased to 24 h instead of 6 to 7 days. The conidia produced by microcycle conidiation were viable and had pigmentation and antagonistic behaviour ...

Arginine metabolism governs microcycle conidiation by changing nitric oxide content in Metarhizium acridum

Applied Microbiology and Biotechnology, 2023
Microcycle conidiation commonly exists in filamentous fungi and has great potential for mass production of mycoinsecticides. L-Arginine metabolism is essential for conidiation and conditional growth and virulence, but its role in microcycle conidiation has not been explored.

Microcycle conidiation in Hirsutella thompsonii

Canadian Journal of Microbiology, 1988
A fermenter method for producing conidiospores of the acarine pathogen, Hirsutella thompsonii, was developed using a strain able to produce microcycle conidiation in submerged culture. The morphological changes occurring during microcycle formation were followed under electron microscopy.

Differential deoxyribonucleic acid synthesis during microcycle conidiation in Neurospora crassa

Archives of Microbiology, 1978
In conidia of Neurospora crassa germinating at 25 degrees C, DNA synthesis measured by incorporation of tritiated adenosine reaches a maximum soon after the outgrowth of the germ tube (6--7 h after inoculation). In conidia heat-treated at 46 degrees C (for 15 h), a maximum of incorporation of the DNA precursor occurs already 1 h after inoculation, then

Microcycle conidiation inPenicillium italicum

Experimental Mycology, 1983
Abstract Penicillium italicum readily conidiates in submerged (shaken) culture in a common carbohydrate-mineral salts medium. At 25°C formation of penicilli is completed within 40 h after inoculation of the nutrient medium with conidia. In medium of proper composition all conidia undergo a true microcycle conidiation, i.e., conidiogenesis ...

Microcycle conidiation in Penicillium urticae: an ultrastructural investigation of conidial germination and outgrowth

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 conidia was initiated by incubation at 37 °C in a growth-favoring medium. Transfer of these enlarged conidia to a nitrogen-poor medium at 35 °C resulted in synchronous germination and limited ...
