Aureobasidium pullulans

Aureobasidium pullulans requires high levels of available water to grow; it is commonly found growing indoors on surfaces that are continually damp, especially in bathrooms and kitchens, on shower curtains, tile grout, window sills and frames, and also in liquid waste materials such as found in condensation pans or humidifier reservoirs. Interestingly, A. pullulans does not appear to require high levels of nutrients commonly needed by other environmental microbes. This species is also extremely sensitive to heat, and can be found in high humidity areas (e.g. window frames and bathrooms). This fungus is implicated rarely in human infections of the eyes and skin, and A. pullulans infections can be found in blood.
