Webfungi were validated using known antifungal-producing fungi. Detection of antifungal activity was often medium dependent. The effects of medium arrays and numbers of strains on detection of antifungal signals were modelled by interpolation of rarefaction curves derived from matrices of positive and nega-tive extracts. WebFigure 1. Typical absorbance curve of bacterial growth. Media conducive to growth, when inoculated with a low concentration of bacteria, will demonstrate an increase in measured absorbance with time as a result of an increase in the number and size of the bacteria. When nutrients become exhausted, growth slows and eventually stops.
