Plant physiologist Sylvia Hua (right) and technician Siov Sarreal display petri dishes showing the effectiveness of a biocontrol yeast against Aspergillus flavus. On the left, a mutant A. flavus turns the agar orange, signifying aflatoxin production. On the right, when the same A. flavus was inoculated between two streaks of yeast, growth was inhibited and no aflatoxin was produced.
