| dc.description.abstract | The specific activity of four isolates of C. subvermispora media was found to be
quite variable. Growth on PDA was the fastest compared to other common nutrient
media. Cardinal temperatures for growth were optimum at 30°C, minimum at 15°C and
maximum at 35°C. Macroscopic characteristics of mycelial mats, in relation to aerial
hyphae production, were also found to differ among different media. Induction of
fruiting was successful with two of the isolates when grown in petri dishes containing 1%
malt extract agar. Basidiocarp production on Pinus banksiana boards was found to be
very effective. Spore germination at 72% was highest with CZ-3 as was spore
production. Single spore isolations and interfertility tests illustrated that C.
subvermispora showed a tetrapolar incompatibility system and not a bipolar system as
previously thought. The production of extracellular polyphenol oxidase in agar based
media was found to be dependant on the type of media used. | |
