The morphology of strain A4 in different ISP
media showed filamentous growth in ISP-5
and ISP-7 media, while pigmentation was
seen in ISP-6 medium. Microscopical
observation (x 10 and x 100 magnification)
after Gram-staining revealed that A4 is a
Gram-positive and rod-shaped microorganism.
Other morphological characteristics
such as colony features, type of areal
hyphae, growth of vegetative hyphae,
fragmentation pattern and spore formation
are detailed in Table 3. They indicate tha
