  • Title: Tolypocladium cylindrosporum (Deuteromycotina: Moniliales), a fungal pathogen of the mosquito Aedes australis. II. Methods of spore propagation and storage.
    Author: Gardner JM, Pillai JS.
    Journal: Mycopathologia; 1987 Feb; 97(2):77-82. PubMed ID: 3574433.
    Abstract:
    A laboratory fermenter was used to produce up to 12 l of infective Tolypocladium cylindrosporum blastoconidia in Sabouraud dextrose broth. Two media derived from coconuts were also demonstrated as suitable alternative systems for the production of viable blastoconidia. T. cylindrosporum conidia when dried at 37 degrees C and stored at 4 degrees C retained their viability for 10 months, but, when stored at 25 degrees C, the conidia lost viability after 2 months and blastoconidia did not survive the drying process. Distilled water suspensions were a simple, economic technique for the long-term storage of spores at both 4 and 25 degrees C. The adsorption of conidia onto silica gel crystals was a very suitable technique for the storage of stock culture material at 4 degrees C. The virulence, production and storage capabilities of both spore types were examined.
