Lessons Learned from M. albus and its relatives

1. Each has 95% -99% 18S rDNA partial sequence similarity to the original isolate of M. albus -620.

2. They make different VOC’s and in differing amounts.

3. They are found as endophytes in the wet tropical regions of the world from Thailand, to Indonesia, Australia, Venezuela, and Peru. They are confined to +/-16 degrees from the equator.

4, Each has some type of bioactivity.

5. Some are being developed for commercial purposes.

6. Many other surprises remain in the jungle.
