Tiivistelmä
Seven Stachybotrys chartarum isolates
were cultured on plain 2% malt extract agar (MEA, control), and MEA with 0.5%
(w/v) pure gypsum (CaSO4 2H2O; GMEA). From
isolates used, five originated from Finnish water-damaged buildings, one from
outdoor air and one from litter (CBS 492.96). All isolates grew densely and
sporulated well on both control and test media. The gypsum-amended medium,
GMEA, was found to enhance S.
chartarum growth considerably compared to MEA: the
difference in colony diameter was significant from the first measurement, 2
days after inoculation. The isolates originating from concrete substrates and
growing most slowly on MEA gained most from the gypsum amendment. The GMEA
medium introduced might be useful for detection of slow-growing S. chartarum, often overgrown by
other mold species on other nutrient media.
