Determination of the ice-nucleating ability of Fusarium caucascium microconidia
Abstract
Recent studies have indicated that biological particles may be an important class of ice nuclei on regional scales. Quantitative measurements on the immersion ice-activity of spores of the common genus Fusarium have been performed. Droplets containing an average of approximately five Fusarium caucasicum microconidia were found to have a median freezing temperature of -33.6°C. The activity spectrum revealed that 0.1% and 1% of spores are active at -29.1°C and -30.7°C, respectively.
