Both the people in the US said they never got any plastic bits in the mail. People are still really interested; would it be possible to send out one or two more?

Hace unos meses envie por correo muestras de PVC degrdadado a dos colegas en EEUU para que hicieran los aislamiento del hongo, no he recibido informacion sobre esto. No se si esta especie produce taxol, no tengo el equipo para dteerminar esto.

We found too a Cladosporium associated with the pvc degradation, possible Cladosporium resinae (Lindau) De Vries, that is reported eating petroleum derivates.

Pestalotiopsis genera have a acervuli,(Melanconiales) sometimes of 2 – 3 mm. wide, and its possible see without microscope.

I would ask that we know the northern limit of it’s range and for some photos of the fruit body. How many of this genera or other fungi do the same? Is this the only one in the world that does this or is this just the first of a massive section that does the same?

It is an asco that makes

perithecia when proper fruiting conditions occur, I wonder how large those can become?

What a cool fungus! it eats plastic and produces taxol, what else could you ask for?

Thank you Eduardo!

Great post. I am very interested to see what else can come out of this. Does Pestalotiopsis microspora have a fruit body that is large enough to see with the naked eye?

Yes, but better I can send you a sample of bio-degradated pvc bags, and you can isolated all microorganisms associated.

Very cool!!!

Is there any chance you could capture this culture on agar?

The Pestalotiopsis microspora was found using a plastic as sustrate. In Panama plant nurseries we have the problem with a rapid dregadation of PVC plastics bags use for seedlings, and we think is due to action of several fungi and bacteria, but we dont not research in this theme yet.
