Bio-remediation, Take 2! (Herbicide Clean-up)

This thread subject was attempted before but I felt the incessant ego rearing it's ugly head had tarnished it thus I thought it'd be better to start anew and begin a fresh thread which you read now 
I just read this study from 2013 titled "Biodegradation of Glyphosate by fungal strains isolated from herbicides polluted-soils..." and wanted to discuss it with humans that may find it interesting.
Glyphosate, the organophosphorous compound in Monsanto's RoundUp, is used pretty liberally in our society today, including the land that I live on, thus why I began digging into scientific journal: To see how I could help restore my environment.
I found it interesting that the fungi used in the study were all of the Ascomycota phylum. This interest me because most of the time I hear about fungi in Bioremediation they are typically of the Basidiomycota....specifically Pleurotous. Again, I am completely amateur at this so cannot confidentally draw many conclusions as to why this is so.
Maybe Ascomycota are more successful at breaking toxins down because they don't put effort into fruiting? Or could simply be the interest or bias of those conducting the study.
Varieties of species belonging to the genus Asperillgus and Penicillium were found with most success and were spread with what sounds like what Stamet's describes as a Spore Slurry in GG&MM.
Another interesting note is they found the glyphosphate (to an extent) increased microbial activity! Don't let Monsanto get a hold of that information 
Anyone else nerd in' out on scientific journals on a Friday Night? Let's talk fung

They pick the species depending on how well it is cultivated locally. This is why oyster is normally used, it grows in a variety of climates and is already readily available. The species chosen is more about cost and availability rather than other traits.
I recently read the same article and found it interesting but organophosphates readily absorb into the water table, plants, animals, etc.. it would only help remove so much but nonetheless it is a partial relieve to the buildup of the salts.

The reason Glyphosate is used so much is that it breaks down quickly on its own without needing any fungi or bacteria to break it down.
It is also one of the least toxic herbicides ever deployed, so I am not sure why it needs to be remediated.

the half life in aerobic soil is very short (40-140 days), even shorter in anaerobic soil and water. it is broken down by hydrolysis and microbial degradation fairly easily.

So how long does it take 18 to 23 million pounds A YEAR SINCE THE 1970s to degrade?
Glyphosphate has created all kinds of resentment towards heterologous gene products and really crippled their application to crops thanks to new anti-GMO laws inspired by glyphosphate resistant products.

alot, but there are much worse pesticides out there, and hydrocarbons, etc, that don't have natural pathways to degradation or, if they do, take much much longer. anyway, i was just providing information, not saying it shouldn't be done. Also, pointed out that Alan was wrong, that bacteria and fungi do play a role in the breakdown of glyphosphate in the soil. maybe he meant additional microorganisms?

Just because it is the "least toxic" doesn't cease my motivation to get it out of my environment. Gotta start somewhere, right?

I appreciate your clarification and information. Thank you.
So in terms of cleaning up ones without natural pathways to degradation, we're are pretty SOL at this point?

No you filter them out with a container species or equipment and then degrade them at a hazardous waste processing plant synthetically. Only problem is, nobody cares enough and its expensive 
If we had more public support, stricter regulations on usage rates, and grant money there wouldnt be much of an issue with pollution
