The blastospore production media consisted of the previously
described basal salts medium amended with cottonseed
flour at 25 g L−1 (Pharmamedia®, Traders Protein, Memphis,
TN, USA) as the nitrogen source using various concentrations
of glucose. The standard glucose concentration for the blastospore
production media was 100 g L−1 glucose unless otherwise
stated. All blastospore production media were inoculated
with blastospores from 3-day-old pre-cultures to deliver a final
blastospore concentration of 5×106 blastospores mL−1. The
initial pH of the media was 5.5 and was uncontrolled during
culture growth. Cultures were evaluated at 48 and 72 h for
biomass accumulation and blastospore formation. Flasks were
hand shaken, as needed, to reduce fungal growth on the flask
walls. Two shake flasks (replicates) per experimental treatment
were used for each experiment, and all experiments were
independently repeated three times (n=6).
