everyone I've seen that has tried it says that it makes mycelium grow faster. i reckon it's a readily available form of carbon but that's just a guess.

I am using it to try to increase spore germination in Ganoderma. One of the studies I read used activated carbon in conjunction with Rhodotorula yeast to germinate mycorrhizal spores. The study suggested that autoclaving the agar produces inhibitory substances and the addition of activated carbon helps to clear these up.

The good news is though that if your culture produces those little black liquid balls... you now have tons of spores to make more cultures with and see if you can't find one that does a better job at eating the plastic than the parent culture.
Aren't the black dots pools of conidiospores? Since conidiospores are asexual they'd be genetically identical to the parent, right? Or is there genetic variation in conidiospores?
In case there is, i've tried germinating some in 10% and 5% PUR. They are germinating fine in the 5% but having a much harder time in the 10%. I figure the ones that do survive might have better PUR resistance/degredation abilities.
I've also made some plates of agar mixed with PUR though somewhere in the process there was contamination of Black Mold. This turned out to be kind of lucky since black mold was used as a positive control in the article since it also has plastic eating capabilities. http://www.jairjp.com/NOVEMBER%202012/08%20RAAMAN.pdf
There were no zones of clearance on the contaminated plates so I assume that this method doesn't work. I think for a zone of clearance to happen the media needs to be liquid. I've started some plates with liquid MEA and PUR. I've done one plate with a agar wedge and another with the condiospores. After 3 days a zone of of clearance seems to be forming around the wedge and all across the condiospore inoculated plate!

Not sure, you are probably right, they seem to be a form of conidia which are asexual. It seems these spores observed will make essentially a clone, if I understand conidia correctly.
The genetics of Pestalotiopsis is odd.

Sexual and asexual forms
One fifth of all known anamorphic fungi lack known sexual states (Shearer et al. 2007), and out of 2,873 anamorphic genera names, 699 genera and 94 anamorph-like genera are linked to a sexual state (Hyde et al. 2011). The links between sexual and asexual stage are mostly from indirect evidence, with some links known through experimental or molecular data (Kendrick 1979; Reynolds 1993; Shenoy et al. 2007; Hyde et al. 2011). Pestalotiopsis is a species-rich anamorphic genus with species mostly lacking sexual morphogenesis, unlike the coelomycetous genera Colletotrichum and Phyllosticta (Armstrong-Cho and Banniza 2006; Wulandari et al. 2009) and Penicillium (Cannon and Kirk 2000). The sexual states or teleo morphs of Pestalotiopsis species have been identified as Pestalosphaeria (Barr 1975) and Neobroomella (Kirk et al. 2008). The asexual Pestalotiopsis state and ascomycetous sexual state have rarely been recorded in the same host plant (Barr 1975; Nag Raj 1985; Hyde 1996). However, it is not always clear that the two stages found are definitely the same biological species and therefore molecular evidence is needed to link them. In the laboratory species of Pestalotiopsis rarely develop sexual forms (Metz et al. 2000). Zhu et al. (1991) induced Pestalosphaeria accidenta P.L. Zhu, Q.X. Ge & T. Xu and P. jinggangensis P.L. Zhu, Q.X. Ge & T. Xu to form on potato dextrose agar (PDA). However, this took 5 to 6 months of incubation. Metz et al. (2000) obtained the sexual state of P. microspora, an endophytic isolate that produced taxol. The asexual stage formed after 3–6 weeks on water agar with dried yew needles when incubated at 16–20 C with 12 h of light per day and was identified as Pestalosphaeria hansenii Shoemaker & J.A. Simpson. The twelve sexual states known for species of Pestalotiopsis are listed in Table 1.

no, it is not. I am selling them for $20 and I am not profiting off of it. Also that price was not set by me

Yes I think I read somewhere in this huge thread, about the co-op. That's a good deal, but $80?

Hello,
I am interested in P. microspora if someone is asking for a reasonable price.
Thank you.

I would love to help you out. I had a trade with SineWaveHighway, but he's totally disappeared, with my petri dishes, and I got nothing. Don't think he's been on since middle of November 2015. Stay away from that one if he offers.

Ganzig said: That is a good idea Alan. I was thinking about mixing plastics straight into an agar solution as well as feeding plastics to it.
I question the use of agar as a medium for plastic eating microbes. There are such things as agar degrading microbes otherwise the oceans would be full of agar from seaweed by now. Instead, the oceans are filling with plastics which tells us that plastics are far more difficult to degrade. A mixture of agar and plastics would likely select for agar degrading organisms and leave the plastics untouched.
An ideal selective medium would consist of a solution of mineral salts with with a nitrogen source and plastics added as a sole source of carbon. Bits of degraded plastic could be added to this medium in the hope of enriching for something that can grow on plastic. The medium would likely need to be incubated in the dark to prevent the growth of algae.
I suspect anything that can grow on plastic would be a complex group of organisms rather than a single fungus.

Agar can grow many fungi, including plastic eating ones. Good idea about making agar with plastic as the sole nutrient source. Then you could throw all sorts of crap on it and see what grows.
My Pestalotiopsis microspora cultures are doing well, lots of conidiaspores, but it doesn't eat the petri dish. But I guess it is not supposed to, as the dishes are not polyurethane.
Has anyone had any success getting the P. microspora that we have to eat any kind of plastic? Or any failures?

Agar is a carbon source for many organisms and microbes will consume the most readily available carbon source first and then move on to the more difficult. If you mix plastic and agar, the agar will be the first consumed and you will be selecting for organisms that break down agar but not necessarily plastic so agar plus plastic is a poor screening tek.
Nutrient agar is good for maintaining stock cultures but it is not good if you are screening for plastic digesters. Some of the teks described earlier used agar plus polyurethane and they looked for zones of clearing as evidence of plastic digestion and this is a good secondary test once you have found an organism to work with but it would not be good as a selective medium because it has two carbon sources- agar and plastic and agar is certain to be the most digestible.

So a good selective medium would be just plastic?

Liquid with a water based polyurethane mixed in perhaps? Sterilizing is difficult though as the polyurethane likes to separate when heated.
I haven't had any success yet, though I haven't tried more than a few plates so far.

Perhaps it is possible to sterilize at room temperature using some kind of radiation? UV? Xrays? Gamma rays?
I imagine a new container of polyurethane would be completely sterile anyway.
Why sterilize at all? If anything at all grows, that's a win.
Maybe it is better to throw as much dirty crap in there as you can - the dust from an air filter for instance, to try to give thousands of different organisms a chance to eat the plastic.

good point.
Easier to work with non sterile materials anyway, maybe I will mix up some liquid culture mix when I get home and throw some Pestalotiopsis in.
