Aureobasidium pullulans is a spoilage organism,
especially a deteriogenic agent of painted surfaces. It is a
commonly encountered species in wet buildings.
Aureobasidium pullulans is both a soil and leaf
(phylloplane) fungus. In indoor environments, it is very
common on wet wood and window frames, in floor, carpet, and
mattress dust, damp walls, and in humidifier water. It is
occasionally found on a wide range of stored foodstuffs and
cereals (such as wheat, barley and oats). Sometimes it occurs
on meat in cold stores as it can grow at very low
temperatures.
Aureobasidium pullulans is associated with
occupational disease in wood processing. It has also been
isolated from human skin and nails.
Strains of Aureobasidium pullulans are used in various
standard tests for resistance to microbial
degradation.
